TL;DR: In this article, the authors advocate an effective field theory approach to anomalous couplings, which is the natural way to extend the standard model such that the gauge symmetries are respected.

TL;DR: In this paper, it was shown that the dynamical localization transition in both classical and quantum periodically driven ergodic systems in the thermodynamic limit can occur both at classical (Fermi-Ulam model) and at quantum levels (kicked rotor).

TL;DR: In this paper, an extension of relativistic single-particle distribution function for weakly interacting particles at local thermodynamical equilibrium including spin degrees of freedom, for massive spin 1/2 particles is presented.

TL;DR: In this paper, a general framework for the realization of a family of Abelian lattice gauge theories in optical lattices is discussed, and the model has two phases, with the confined entangled one characterized by strings wrapping around the whole lattice.

TL;DR: In this paper, a general procedure to calibrate the detection of a nano/micro-mechanical resonator's displacement as it undergoes thermal Brownian motion is described, followed by a detailed derivation of the corresponding power spectral density (PSD) function, which is identical in all situations aside from a system-dependent effective mass value.

TL;DR: In this article, the theory of 2S−2P Lamb shift and 2S hyperfine splitting in muonic hydrogen combining the published contributions and theoretical approaches has been reviewed, and the prediction of these quantities is necessary for the determination of both proton charge and Zemach radii from the two 2S-2P transition frequencies measured in Muonic hydrogen.

TL;DR: In this article, the lepton asymmetry generated by the out-of-equilibrium decays of heavy Majorana neutrinos with a quasi-degenerate mass spectrum is resonantly enhanced.

TL;DR: In this article, two types of Born-Infeld-like nonlinear electromagnetic fields are considered and the asymptotic behavior of these solutions is the same as that of a Reissner-Nordstrom black hole.

TL;DR: In this paper, the π N scattering amplitude in covariant baryon chiral perturbation theory up to O( p 3 ) was analyzed under the extended-on-mass-shell renormalization scheme and including the Δ ( 1232 ) explicitly in the δ -counting.

TL;DR: Aharonov and Casher as discussed by the authors studied the influence of the Aharonov-Casher effect on the Dirac oscillator in three different scenarios of general relativity: Minkowski spacetime, the cosmic string spacetime and the cosmic dislocation spacetime.

TL;DR: In this article, the parity and time-reversal-violating operators involving quark and gluon fields that have effective dimension six were classified and the form of the effective interactions depends on the chiral properties of these operators.

TL;DR: In this article, the vacuum polarization tensor of a photon propagating in a static and homogeneous magnetic field was computed using Schwinger's proper-time method, and obtained a series representation as a result of double integrals analytically performed with respect to proper time variables, expressed in terms of an infinite sum of known functions which is plausibly interpreted as summation over all the Landau levels of fermions.

TL;DR: In this article, high-order rational solutions for the Hirota equation are constructed based on the parameterized Darboux transformation and several types of this kind of solutions are classified by their structures.

TL;DR: In this article, the functional renormalization group flow of quantum gravity on the Einstein-Cartan theory space is analyzed for the pertinent effective average action for any truncation of this theory space.

TL;DR: In this article, it was shown that in disordered superconducting films that are on the brink of superconductor-insulator transition, the Coulomb forces between the charges acquire two-dimensional character, i.e. the corresponding interaction energy depends logarithmically upon charge separation, bringing the same vortex-charge-BKT transition duality, and realization of superinsulation in the disordered films as the low-temperature charge BKT state.

TL;DR: In this article, an exact solution for the interplay between Bose-Einstein condensation and the Dicke-Hepp-Lieb self-organization transition of an ideal Bose gas trapped inside a single-mode optical cavity and subject to a transverse laser drive is provided.

TL;DR: In this article, the generalizations of Coulomb's law and Debye's screening for power-law non-local media with spatial dispersion have been characterized and the suggested fractional differential models for these plasma-like media are discussed.

TL;DR: In this article, the authors studied the dependence of the number of Gribov copies on the different gauge orbits and established that n is orbit dependent for the minimal lattice Landau gauge.

TL;DR: In this paper, it was shown that invisible localized defects that cannot be detected by an outside observer, can be realized in a crystal with an engineered imaginary potential at the defect site by means of supersymmetric (Darboux) transformations of an ordinary crystal using band-edge wavefunctions.

TL;DR: In this article, the authors applied the Wentzel-Kramers-Brillouin (WKB) approximation to find the reflection and transmission coefficients of two-dimensional massless Dirac fermions.

TL;DR: In this article, the authors derive the Feynman integrand at n loops for a non-abelian gauge theory quantized in a covariant gauge from scalar integrands for connected 3-regular graphs, obtained from the two Symanzik polynomials.

TL;DR: In this article, a quasi-exactly solvable Rabi model is investigated within the framework of the Bargmann Hilbert space of analytic functions, and the eigenvalue equation and eigenfunctions are determined in terms of three systems of monic orthogonal polynomials.

TL;DR: In this article, the relativistic Landau-He-McKellar-Wilkens quantization and bound states solutions for a Dirac neutral particle under the influence of a Coulomb-like potential induced by the Lorentz symmetry breaking effects are discussed.

TL;DR: In this paper, the authors investigated the properties of non-autonomous rogue waves in a Bose-Einstein condensate with a time-dependent harmonic trap with a complex potential.

TL;DR: In this article, the first and second-order supersymmetric quantum mechanics were applied to obtain new exactly solvable real potentials departing from the inverted oscillator potential, and it was shown that these transformations turn out to be the so-called complex ones.

TL;DR: In this paper, it is shown analytically that the real and positive distribution has support in a strip in the complexified configuration space only, in which case correct results are expected.

TL;DR: In this article, a Schrodinger-like equation for the longitudinal wave function of a meson in the valence q q sector, based on the ’t-Hooft model for large- N two-dimensional QCD, was constructed and used to obtain a model for mesons with massive quarks.

TL;DR: In this article, the bound state and scattering problems for a spin- 1/2 particle undergone to an Aharonov-Bohm potential in a conical space in the nonrelativistic limit are considered.

TL;DR: In this paper, the Dirac equation is solved with the mixed scalar-vector-pseudoscalar Cornell potential under spin and pseudospin symmetry limits, and the corresponding eigenfunctions are given in the form of the biconfluent Heun polynomials.
