Vacuum Cherenkov radiation
arXiv:hep-ph/0406128 · doi:10.1103/PhysRevLett.93.110402
Abstract
Within the classical Maxwell-Chern-Simons limit of the Standard-Model Extension (SME), the emission of light by uniformly moving charges is studied confirming the possibility of a Cherenkov-type effect. In this context, the exact radiation rate for charged magnetic point dipoles is determined and found in agreement with a phase-space estimate under certain assumptions.
