1 M ay 2 00 9 Electrodynamics with Lorentz - violating operators of arbitrary dimension
The behavior of photons in the presence of Lorentz and CPT violation is studied. Allowing for operators of arbitrary mass dimension, we classify all gauge-invariant Lorentzand CPT-violating terms in the quadratic Lagrange density associated with the effective photon propagator. The covariant dispersion relation is obtained, and conditions for birefringence are discussed. We provide a complete c...

متن کاملLorentz Violation , Electrodynamics , and the Cosmic Microwave
The properties of light have proved to be a valuable testing ground for special relativity for more than a century. Contemporary experiments are motivated in part by a possible breakdown of special relativity with origins in Planck-scale physics [1, 2, 3]. These experiments include modern versions of the classic Michelson-Morley and Kennedy-Thorndike experiments that use highly stable resonant ...
متن کاملMass and Spin Renormalization in Lorentz Electrodynamics
Lorentz’ objection to the Uhlenbeck-Goudsmit proposal of a spin magnetic moment of the electron, namely that the electron’s equatorial rotation speed would exceed the speed of light by a factor ≈ 10, mutated into an objection against Lorentz electrodynamics (LED) itself when the spin magnetic moment became established. However, Lorentz’ renormalization calculation, based on the early 20th centu...
متن کاملCosmological constraints on Lorentz violation in electrodynamics.
Infrared, optical, and ultraviolet spectropolarimetry of cosmological sources is used to constrain the pure electromagnetic sector of a general Lorentz-violating standard-model extension. The coefficients for Lorentz violation are bounded to less than 3 x 10(-32).
