Particle interference as a test of Lorentz-violating electrodynamics

Abstract

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-violating parameters.
