Non-Minimal Coupling to a Lorentz-Violating Background and Quantum-Mechanical Implications
نویسندگان
چکیده
The non-minimal coupling of fermions to a background responsible for the breaking of Lorentz symmetry is introduced in Dirac’s equation; the non-relativistic regime is contemplated, and the Pauli’s equation is used to to show how an Aharonov-Casher phase appears as a natural consequence of the Lorentz-violating term. Different ways of realizing the Lorentz breaking are presented and, in each case, we show how to relate the Aharonov-Casher phase to the particular components of the background vector or tensor. pacs 03.65.-w, 11.30.Cp, 11.30.Er

UHECR bounds on Lorentz violation in the photon sector
The aim of this brief review is to present a case study of how bounds on Lorentz-violating parameters can be obtained from astrophysics data. For this purpose, a particularly simple Lorentz-violating modification of the Maxwell theory of photons is considered, which maintains gauge invariance, CPT, and renormalization. With a minimal coupling of the photon to a standard spin– 1 2 Dirac particle...
متن کاملGravitational Lorentz Violation and Superluminality via AdS/CFT Duality
A weak quantum mechanical coupling is constructed permitting superluminal communication within a preferred region of a gravitating AdS5 spacetime. This is achieved by adding a spatially non-local perturbation of a special kind to the Hamiltonian of a four-dimensional conformal field theory with a weakly-coupled AdS5 dual, such as maximally supersymmetric Yang-Mills theory. In particular, two is...
متن کاملHydrogen and Antihydrogen Spectroscopy for Studies of CPT and Lorentz Symmetry
A theoretical study of possible signals for CPT and Lorentz violation arising in hydrogen and antihydrogen spectroscopy is described. The analysis uses a CPTand Lorentz-violating extension of quantum electrodynamics, obtained from a general Lorentz-violating extension of the minimal standard model with both CPT-even and CPT-odd terms. Certain 1S-2S transitions and hyperfine Zeeman lines exhibit...
متن کاملLate-time acceleration and Phantom Divide Line Crossing with Non-minimal Coupling and Lorentz Invariance Violation
We consider two alternative dark energy models: a Lorentz invariance preserving model with a nonminimally coupled scalar field and a Lorentz invariance violating model with a minimally coupled scalar field. We study accelerated expansion and dynamics of equation of state parameter in these scenarios. While a minimally coupled scalar field has not the capability to be a successful dark energy ca...
متن کاملParticle interference as a test of Lorentz - violating electrodynamics
In Lorentz-violating electrodynamics a steady current (and similarly a static charge) generates both static magnetic and electric fields. These induced fields, acting on interfering particles, change the interference pattern. We find that particle interference experiments are sensitive to small Lorentz violating effects, and thus they can be used to improve current bounds on some Lorentz-violat...
