SFI is related to the important methods of Integrations By Parts and of Differential Equations. It is shown that sometimes there exist a locus in parameter space where the set of SFI differential equations degenerates into an algebraic equation, thereby enabling a solution in terms of integrals associated with degenerations of the diagram. This is demonstrated by the two-loop vacuum diagram, where the algebraic locus can be interpreted as a threshold phenomenon and is given by the zeros of the Baikov polynomial. In addition, the symmetry group is interpreted geometrically as linear transformations of loop currents which preserve the subspace of squared currents within the space of quadratics in loop currents. \\ ( https://arxiv.org/abs/1604.07827 , 327kb) ------------------------------------------------------------------------------ \\ arXiv:1604.07830 Date: Tue, 26 Apr 2016 20:00:09 GMT (1434kb) Title: Finite size effect on dynamical entanglement entropy: CFT and holography Authors: Gautam Mandal, Ritam Sinha, and Tomonori Ugajin Categories: hep-th Comments: 44 pages, many figures Report-no: TIFR/TH/16-16 \\ Time-dependent entanglement entropy (EE) is computed for a single interval in two-dimensional conformal theories from a quenched initial state in the presence of spatial boundaries. The EE is found to be periodic in time with periodicity equal to the system size $L$. For large enough $L$, the EE shows a rise to a thermal value (characterized by a temperature $1/\beta$ determined by the initial state), followed by periodic returns to the original value. This works irrespective of whether the conformal field theory (CFT) is rational or irrational. For conformal field theories with a holographic dual, the large $c$ limit plays an essential role in ensuring that the EE computed from the CFT is universal (independent of the details of the CFT and of boundary conditions) and is exactly matched by the holographic EE. The dual geometry is computed and it interpolates between a BTZ black hole at large $L$ and global AdS at large $\beta$. \\ ( https://arxiv.org/abs/1604.07830 , 1434kb) ------------------------------------------------------------------------------ \\ arXiv:1604.07837 Date: Mon, 25 Apr 2016 08:01:01 GMT (13kb) Title: Conserved Charges of Minimal Massive Gravity Coupled to Scalar Field Authors: M. R. Setare and H. Adami Categories: hep-th Comments: 22 pages, no figure \\ Recently, the theory of Topologically massive gravity non-minimally coupled to a scalar field has been proposed which comes from Lorentz-Chern-Simons theory \cite{1}. That theory is a torsion free one. We extend that theory by adding an extra term which makes torsion to be non-zero. The extended theory can be regarded as an extension of Minimal massive gravity such that it is non-minimally coupled to a scalar field. We obtain equations of motion of extended theory such that they are expressed in terms of usual torsion free spin-connection. We show that BTZ spacetime is a solution of this theory when scalar field is constant. We define quasi-local conserved charge by the concept of generalized off-shell ADT current which both are conserved for any asymptotically Killing vector field as well as a Killing vector field which is admitted by spacetime everywhere. Also we find general formula for entropy of stationary black hole solution in the context of considered theory. We apply the obtained formulas on BTZ black hole solution, to calculate energy, angular momentum and entropy of this soultion. We obtain the central extension term, the central charges and the eigenvalues of the Virasoro algebra generators for the BTZ black hole solution. We calculate energy and angular momentum of BTZ black hole using the eigenvalues of the Virasoro algebra generators. Also we calculate the entropy of BTZ black hole by using the Cardy formula. We find that obtained results using two different ways are exactly matched as we expected. \\ ( https://arxiv.org/abs/1604.07837 , 13kb) ------------------------------------------------------------------------------ \\ arXiv:1604.07841 Date: Tue, 26 Apr 2016 20:08:55 GMT (162kb,D) Title: Loop Corrections to Standard Model Fields in Inflation Authors: Xingang Chen, Yi Wang, Zhong-Zhi Xianyu Categories: hep-th astro-ph.CO hep-ph Comments: 32 pages, 8 figures \\ We calculate 1-loop corrections to the Schwinger-Keldysh propagators of Standard-Model-like fields of spin-0, 1/2, and 1, with all renormalizable interactions during inflation.

Thompson Categories: hep-th Comments: 56 pages, 19 figures \\ We study the $SU(2)$ Principal Chiral Model (PCM) in the presence of an integrable $\eta$-deformation. We put the theory on $\mathbb{R}\times S^1$ with twisted boundary conditions and then reduce the circle to obtain an effective quantum mechanics associated with the Whittaker-Hill equation. Using resurgent analysis we study the large order behaviour of perturbation theory and recover the fracton events responsible for IR renormalons. The fractons are modified from the standard PCM due to the presence of this $\eta$-deformation but they are still the constituents of uniton-like solutions in the deformed quantum field theory. We also find novel $SL(2,\mathbb{C})$ saddles, thus strengthening the conjecture that the semi-classical expansion of the path integral gives rise to a resurgent transseries once written as a sum over Lefschetz thimbles living in a complexification of the field space. We conclude by connecting our quantum mechanics to a massive deformation of the $\mathcal{N}=2~$ $4$-d gauge theory with gauge group $SU(2)$ and $N_f=2$. \\ ( https://arxiv.org/abs/1604.07851 , 3257kb) ------------------------------------------------------------------------------ \\ arXiv:1604.07860 Date: Tue, 26 Apr 2016 21:19:25 GMT (15kb) Title: The Tensor Track, IV Authors: Vincent Rivasseau Categories: hep-th math-ph math.MP Comments: Proceedings of the Corfu Summer Institute 2015 "School and Workshops on Elementary Particle Physics and Gravity", 1-27 September 2015, Corfu, Greece, 13 pages \\ This note is a sequel to the previous series "Tensor Track I-III".

We continue to study the purely bosonic $D=4$ effective action, and elucidate how the addition of scalar potential term still allows Killing spinor equations in the absence of gauge fields. In particular, the potential turns out to be a single diagonal component of the coset representative. Furthermore, we perform a general analysis of the integrability conditions of Killing spinor equations and establish that the effective action can be in fact generalized to arbitrary sizes and signatures, e.g. with target $SL(n,\mathbb{R})/SO(p,n-p)$ and the scalar potential expressible by a single diagonal component of the coset representative. We also comment on a similar construction and its generalizations of effective $D=5$ purely bosonic non-linear sigma model action related to AdS$_6$ in M-theory. \\ ( https://arxiv.org/abs/1604.07987 , 22kb) ------------------------------------------------------------------------------ \\ arXiv:1604.08027 Date: Wed, 27 Apr 2016 11:58:08 GMT (2832kb,AD) Title: Massless scalar Feynman diagrams: five loops and beyond Authors: David J. Broadhurst Categories: hep-th math.NT Comments: report of The Open University, Milton Keynes, England (UK), 1985, copy provided by John Gracey, http://cds.cern.ch/record/164890, LaTeX reproduction by Erik Panzer Report-no: OUT-4102-18 \\ Several powerful techniques for evaluating massless scalar Feynman diagrams are developed, viz: the solution of recurrence relations to evaluate diagrams with arbitrary numbers of loops in $n=4-2\omega$ dimensions; the discovery and use of symmetry properties to restrict and compute Taylor series in $\omega$; the reduction of triple sums over Chebyshev polynomials to products of Riemann zeta functions; the exploitation of conformal invariance to avoid four-dimensional Racah coefficients. As an example of the power of these techniques we evaluate all of the 216 diagrams, with 5 loops or less, which give finite contributions of order $1/k^2$ or $1/k^4$ to a propagator of momentum $k$ in massless four-dimensional scalar field theories. Remarkably, only 5 basic numbers are encountered: $\zeta(3)$, $\zeta(5)$, $\zeta(7)$, $\zeta(9)$ and the value of the most symmetrical diagram, which is calculated to 14 significant figures. It is conceivable that these are the only irrationals appearing in 6-loop beta functions. En route to these results we uncover and only partially explain many remarkable relations between diagrams. \\ ( https://arxiv.org/abs/1604.08027 , 2832kb) ------------------------------------------------------------------------------ \\ arXiv:1604.08032 Date: Wed, 27 Apr 2016 12:08:11 GMT (414kb,D) Title: Scale Factor Duality for Conformal Cyclic Cosmologies Authors: U. Camara dS, A.L. Alves Lima and G.M. Sotkov Categories: hep-th gr-qc Comments: 37 pages, 6 figures \\ The scale factor duality is a symmetry of dilaton gravity which is known to lead to pre-big-bang cosmologies. A conformal time version of the scale factor duality (SFD) was recently implemented as a UV/IR symmetry between decelerated and accelerated phases of the post-big-bang evolution within Einstein gravity coupled to a scalar field. The problem investigated in the present paper concerns the employment of the conformal time SFD methods to the construction of pre-big-bang and cyclic extensions of these models. We demonstrate that each big-bang model gives rise to two qualitatively different pre-big-bang evolutions: a contraction/expansion SFD model and Penrose's Conformal Cyclic Cosmology (CCC). A few examples of SFD symmetric cyclic universes involving certain gauged K\"ahler sigma models minimally coupled to Einstein gravity are studied. We also describe the specific SFD features of the thermodynamics and the conditions for validity of the generalized second law in the case of Gauss-Bonnet (GB) extension of these selected CCC models. \\ ( https://arxiv.org/abs/1604.08032 , 414kb) ------------------------------------------------------------------------------ \\ arXiv:1604.08042 Date: Wed, 27 Apr 2016 12:35:46 GMT (14kb) Title: Three-Dimensional Extended Bargmann Supergravity Authors: Eric A.

We show that this three-dimensional `Extended Bargmann Gravity', after coupling to matter, leads to equations of motion allowing a wider class of background geometries than the ones that one encounters in Newtonian gravity. We give the supersymmetric generalization of these results and point out an important application in the context of calculating partition functions of non-relativistic field theories using localization techniques. \\ ( https://arxiv.org/abs/1604.08042 , 14kb) ------------------------------------------------------------------------------ \\ arXiv:1604.08054 Date: Wed, 27 Apr 2016 13:08:08 GMT (19kb) Title: Non-Relativistic Chern-Simons Theories and Three-Dimensional Horava-Lifshitz Gravity Authors: Jelle Hartong, Yang Lei, Niels A. Obers Categories: hep-th gr-qc Comments: 9 pages Report-no: DCPT-16/13 \\ We show that certain three-dimensional Horava-Lifshitz gravity theories can be written as Chern-Simons gauge theories on various non-relativistic algebras. The algebras are specific extensions of the Bargmann, Newton-Hooke and Schroedinger algebra each of which has the Galilean algebra as a subalgebra. To show this we employ the fact that Horava-Lifshitz gravity corresponds to dynamical Newton-Cartan geometry. In particular, the extended Bargmann (Newton-Hooke) Chern-Simons theory corresponds to projectable Horava-Lifshitz gravity with a local U(1) gauge symmetry without (with) a cosmological constant. Moreover we identify an extended Schroedinger algebra containing 3 extra generators that are central with respect to the subalgebra of Galilean boosts, momenta and rotations, for which the Chern-Simons theory gives rise to a novel version of non-projectable conformal Horava-Lifshitz gravity that we refer to as Schroedinger gravity. This theory has a z=2 Lifshitz geometry as a vacuum solution and thus provides a new framework to study Lifshitz holography. \\ ( https://arxiv.org/abs/1604.08054 , 19kb) ------------------------------------------------------------------------------ \\ arXiv:1604.08064 Date: Wed, 27 Apr 2016 13:36:53 GMT (638kb) Title: Using Cardy-Jacobsen and Yaffe-Svetitsky Conjectures to Solve the Cosmological Domain Wall and Dark Matter Overproduction problems Authors: Hadi Gholian Aval Categories: hep-th \\ In this paper I will combine and use two Cardy-Jacobsen and Yaffe-Svetitsky conjectures [1, 2] to present a mechanism for a late-time inflation during the electroweak symmetry breaking due to discrete Z_3 symmetry at O(10^2 ) GeV and a psudo-inflation at O(10^2 ) MeV scale in order to solve the cosmological domain wall problem and thermal and non-thermal relics overproduction in the early universe. We will see that Cardy-Jacobsen conjecture and Zeldovic statement for cosmological domain wall problem are incompatible. Also, in the psudo-inflation mechanism presented here there would be a latent heat release and entropy injection without an exponential expansion and reheating period. \\ ( https://arxiv.org/abs/1604.08064 , 638kb) ------------------------------------------------------------------------------ \\ arXiv:1604.08203 Date: Wed, 27 Apr 2016 19:59:26 GMT (24kb) Title: Black hole thermodynamics, conformal couplings, and R^2 terms Authors: Mariano Chernicoff, Mario Galante, Gaston Giribet, Andres Goya, Matias Leoni, Julio Oliva and Guillem Perez-Nadal Categories: hep-th gr-qc Comments: 24 pages, no figures \\ Lovelock theory provides a tractable model of higher-curvature gravity in which several questions can be studied analytically. This is the reason why, in the last years, this theory has become the favorite arena to study the effects of higher-curvature terms in the context of AdS/CFT correspondence. Lovelock theory also admits extensions that permit to accommodate matter coupled to gravity in a non-minimal way. In this setup, problems such as the backreaction of matter on the black hole geometry can also be solved exactly. In this paper, we study the thermodynamics of black holes in theories of gravity of this type, which include both higher-curvature terms, U(1) gauge fields, and conformal couplings with matter fields in D dimensions. These charged black hole solutions exhibit a backreacting scalar field configuration that is regular everywhere outside and on the horizon, and may exist both in asymptotically flat and asymptotically Anti-de Sitter (AdS) spaces. We work out explicitly the boundary action for this theory, which renders the variational problem well-posed and suffices to regularize the Euclidean action in AdS. We also discuss several interrelated properties of the theory, such as its duality symmetry under field redefinition and how it acts on black holes and gravitational wave solutions. \\ ( https://arxiv.org/abs/1604.08203 , 24kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1604.05544 (*cross-listing*) Date: Tue, 19 Apr 2016 12:49:55 GMT (61kb,D) Title: Jarzynski's theorem for lattice gauge theory Authors: Michele Caselle, Gianluca Costagliola, Alessandro Nada, Marco Panero, Arianna Toniato Categories: hep-lat cond-mat.stat-mech hep-th Comments: 1+29 pages, 2 pdf figures Report-no: CP3-Origins-2016-020 DNRF90, DIAS-2016-20 \\ Jarzynski's theorem is a well-known equality in statistical mechanics, which relates fluctuations in the work performed during a non-equilibrium transformation of a system, to the free-energy difference between two equilibrium states.

Supplemental Mathematica notebook available at http://centra.tecnico.ulisboa.pt/network/grit/files/ \\ In viable models of minicharged dark matter, astrophysical black holes might be charged under a hidden $U(1)$ symmetry and are formally described by the same Kerr-Newman solution of Einstein-Maxwell theory. These objects are unique probes of minicharged dark matter and dark photons. We show that the recent gravitational-wave detection of a binary black-hole coalescence by aLIGO provides various observational bounds on the black hole's charge, regardless of its nature. The pre-merger inspiral phase can be used to constrain the dipolar emission of (ordinary and dark) photons, whereas the detection of the quasinormal modes set an upper limit on the final black hole's charge. By using a toy model of a point charge plunging into a Reissner-Nordstrom black hole, we also show that in dynamical processes the (hidden) electromagnetic quasinormal modes of the final object are excited to considerable amplitude in the gravitational-wave spectrum only when the black hole is nearly extremal. The coalescence produces a burst of low-frequency dark photons which might provide a possible electromagnetic counterpart to black-hole mergers in these scenarios. \\ ( https://arxiv.org/abs/1604.07845 , 732kb) ------------------------------------------------------------------------------ \\ arXiv:1604.07854 (*cross-listing*) Date: Tue, 26 Apr 2016 20:56:36 GMT (6kb) Title: Generalized Dirac duality and CP violation in a two photon theory Authors: P.

Echevarria, Ignazio Scimemi, Alexey Vladimirov Categories: hep-ph hep-th Comments: 40 pages, 2 figures \\ The transverse momentum dependent parton distribution/fragmentation functions (TMDs) are essential in the factorization of a number of processes like Drell-Yan scattering, vector boson production, semi-inclusive deep inelastic scattering, etc. We provide a comprehensive study of unpolarized TMDs at next-to-next-to-leading order, which includes an explicit calculation of these TMDs and an extraction of their matching coefficients onto their integrated analogues, for all flavor combinations. The obtained matching coefficients are important for any kind of phenomenology involving TMDs. In the present study each individual TMD is calculated without any reference to a specific process. We recover the known results for parton distribution functions and provide new results for the fragmentation functions. The results for the gluon transverse momentum dependent fragmentation functions are presented for the first time at one and two loops. We also discuss the structure of singularities of TMD operators and TMD matrix elements, crossing relations between TMD parton distribution functions and TMD fragmentation functions, and renormalization group equations. In addition, we consider the behavior of the matching coefficients at threshold and make a conjecture on their structure to all orders in perturbation theory. \\ ( https://arxiv.org/abs/1604.07869 , 244kb) ------------------------------------------------------------------------------ \\ arXiv:1604.07899 (*cross-listing*) Date: Wed, 27 Apr 2016 01:17:44 GMT (98kb,D) Title: Gravitational Waves in Bouncing Cosmologies from Gauge Field Production Authors: Ido Ben-Dayan Categories: astro-ph.CO gr-qc hep-ph hep-th Comments: 35 pages, 5 figures. Comments are welcome \\ We calculate the gravitational waves (GW) spectrum produced in various Early Universe scenarios from gauge field sources, thus generalizing earlier inflationary calculations to bouncing cosmologies. We consider generic couplings between the gauge fields and the scalar field dominating the energy density of the Universe. We analyze the requirements needed to avoid a backreaction that will spoil the background evolution. When the scalar is coupled only to $F \tilde F$ term, the sourced GW spectrum is exponentially enhanced and parametrically the square of the vacuum fluctuations spectrum, ${\cal P}^s_T\sim ({\cal P}^v_T)^2$, giving an even bluer spectrum than the standard vacuum one. When the scalar field is also coupled to $F^2$ term, the amplitude is still exponentially enhanced, but the spectrum can be arbitrarily close to scale invariant (still slightly blue), $n_T\gtrsim 0$, that is distinguishable form the slightly red inflationary one. Hence, we have a proof of concept of observable GW on CMB scales in a bouncing cosmology. \\ ( https://arxiv.org/abs/1604.07899 , 98kb) ------------------------------------------------------------------------------ \\ arXiv:1604.07932 (*cross-listing*) Date: Wed, 27 Apr 2016 04:26:50 GMT (12kb) Title: Regularization of Kepler Problem in $\kappa$-spacetime Authors: Partha Guha, E.

Their salient feature is that the isometry group includes the conformal subgroup SO(2,1). In this work, we turn the logic around and use the conformal invariants for constructing Ricci-flat metrics in d=4 and d=5 where the vacuum Einstein equations reduce to a coupled set of ordinary differential equations. In four dimensions the analysis can be carried out in full generality and the resulting metric describes the d=4 near horizon Kerr-NUT black hole. In five dimensions we choose a specific ansatz whose structure is similar to the d=5 near horizon Myers-Perry black hole. A Ricci-flat metric involving five arbitrary parameters is constructed. A particular member of this family, which is characterized by three parameters, seems to be a natural candidate to describe the d=5 near horizon Myers-Perry black hole with a NUT charge. \\ ( https://arxiv.org/abs/1604.08056 , 10kb) ------------------------------------------------------------------------------ \\ arXiv:1604.08067 (*cross-listing*) Date: Wed, 27 Apr 2016 13:42:37 GMT (20kb) Title: Emergent Gravity from an Augmented Variational Principle Authors: Matteo Tuveri, Lorenzo Fatibene and Marco Ferraris Categories: gr-qc hep-th \\ A direct and non-trivial link between Padmanabhan's entropy used in emergent gravity and standard GR action is established.

The $N-1$ domain walls behave as insulators separating $N$ superconductors. We construct the effective Lagrangian on the domain walls, which reduces to a coupled sine-Gordon model for well-separated walls and contains more interactions for walls at short distance. We then construct sine-Gordon solitons emerging in the effective theory that we identify Josephson vortices carrying singly quantized magnetic fluxes. When two neighboring superconductors tend to have the same phase, the ground state does not change with the positions of domain walls. On the other hand, when two neighboring superconductors tend to have the $\pi$ phase differences, the ground state has a phase transition depending on the positions of domain walls; when the two walls are close to each other, frustration occurs because of the coupling between the two superconductors besides the thin superconductor. Focusing on the case of three superconductors separated by two insulators, we find for the former case that the interaction between two Josephson vortices on different insulators changes its nature, i.e., attractive or repulsive, depending on the positions of domain walls. In the latter case, there emerges fractional Josephson vortices when two degenerate ground states appear due to spontaneous charge-symmetry breaking, and the number of the Josephson vortices varies with the position of domain walls. Our predictions should be verified in multi-layered Josephson junctions. \\ ( https://arxiv.org/abs/1604.08103 , 5586kb) ------------------------------------------------------------------------------ \\ arXiv:1604.08174 (*cross-listing*) Date: Tue, 26 Apr 2016 19:57:18 GMT (64kb) Title: Quark-hadron phase structure and QCD equations of state in vanishing and finite magnetic field Authors: Abdel Nasser Tawfik, Abdel Magied Diab (Egyptian Ctr. Theor. Phys., Cairo, WLCAPP, Cairo) and M. T. Hussein (Cairo U.) Categories: hep-lat hep-ph hep-th Comments: 18 pages, 7 figures, submitted to EPJA Report-no: ECTP-2014-09, WLCAPP-2014-09 \\ In characterizing the quark-hadron phase structure, determining various thermodynamic quantities and investigating their temperature dependencies on vanishing and finite magnetic field, SU(3) Polyakov linear-sigma model (PLSM) is utilized. The dependence of the chiral order-parameter on vanishing and finite magnetic field is calculated in mean-field approximation. In a wide range of temperatures and magnetic field strengths, the thermodynamic observables including trace anomaly, speed of sound squared, entropy density, specific heat and magnetization are presented. An excellent agreement is found when these are confronted to recent lattice QCD calculations. The temperature dependence of these quantities confirms our previous result that the transition temperature is reduced with magnetic field. Furthermore, the temperature dependence of magnetization verifies the conclusion that the QCD matter has paramagnetic properties near and far above the critical temperature. The excellent agreement with recent lattice calculations means that PLSM possesses the correct degrees of freedom in both hadronic and partonic phases and describes well dynamics deriving confined hadrons to deconfined quark-gluon plasma. The magnetic field seems to enhance the occurrence of chiral phase-transition due to its contributions to the Landau quantizations and contribute to the suppression in the chiral condensates relevant to the restoration of the chiral symmetry-breaking. The inverse magnetic catalysis leads to a decrease in the chiral critical temperature with increasing magnetic field. We remark that PLSM has a temperature-limited applicability depending on the temperature-applicability of its chiral and deconfinement order-parameters. Only within this limit the conclusions about equation of state, chiral phase-structure and magnetic properties, etc. can be relatively certain. \\ ( https://arxiv.org/abs/1604.08174 , 64kb) ------------------------------------------------------------------------------ \\ arXiv:1604.08193 (*cross-listing*) Date: Wed, 13 Apr 2016 20:00:30 GMT (10kb) Title: Discrete Symmetry Transformation of Baryon- and Lepton-Nonconserving Processes Authors: Ehsan Jafari Categories: hep-ph hep-th Comments: 6 pages \\ In this paper we consider discrete symmetry (C, P, T and CP) transformations of baryon- and lepton-nonconserving processes. According to our calculation it is not possible to definite exact discrete symmetry transformation for any operator which breaks $B-L$ and changes the number of fundamental fermions between initial and final states. In order to count the net change of fundamental fermions between initial and final states, $F$ number has been introduced. On the other hand from theoretical point of view we are not able to label operators which break $B-L$ and violate F number as $-even$ or $-odd$ under the effect of discrete symmetries. \\ ( https://arxiv.org/abs/1604.08193 , 10kb) ------------------------------------------------------------------------------ \\ arXiv:1604.08199 (*cross-listing*) Date: Wed, 27 Apr 2016 19:49:09 GMT (12kb) Title: Kinematical uniqueness of homogeneous isotropic LQC Authors: Jonathan Engle and Maximilian Hanusch Categories: gr-qc hep-th math-ph math.MP Comments: 7 pages \\ In a paper by Ashtekar and Campiglia, invariance under volume preserving residual diffeomorphisms has been used to single out the standard representation of the reduced holonomy-flux algebra in homogeneous loop quantum cosmology (LQC). In this paper, we use invariance under all residual diffeomorphisms to single out the standard kinematical Hilbert space of homogeneous isotropic LQC for both the standard configuration space $\mathbb{R}_{\mathrm{Bohr}}$, as well as for the Fleischhack one $\mathbb{R} \sqcup \mathbb{R}_{\mathrm{Bohr}}$. We first determine the scale invariant Radon measures on these spaces, and then show that the Haar measure on $\mathbb{R}_{\mathrm{Bohr}}$ is the only such measure for which the momentum operator is hermitian w.r.t. the corresponding inner product. In particular, the measure is forced to be identically zero on $\mathbb{R}$ in the Fleischhack case, so that for both approaches, the standard kinematical LQC-Hilbert space is singled out. \\ ( https://arxiv.org/abs/1604.08199 , 12kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1412.3872 replaced with revised version Wed, 27 Apr 2016 08:21:02 GMT (1153kb,D) Title: The Superconformal Index of the (2,0) Theory with Defects Authors: Mathew Bullimore and Hee-Cheol Kim Categories: hep-th Comments: 47 pages, 5 figures, Version 2: minor corrections, references updated, JHEP version DOI: 10.1007/JHEP05(2015)048 \\ ( https://arxiv.org/abs/1412.3872 , 1153kb) ------------------------------------------------------------------------------ \\ arXiv:1504.04037 (*cross-listing*) replaced with revised version Tue, 26 Apr 2016 22:00:35 GMT (60kb) Title: Can Dark Matter be a Scalar Field?
