Vacuum Cherenkov radiation in spacelike Maxwell-Chern-Simons theory
C. Kaufhold, F. R. Klinkhamer
A detailed analysis of vacuum Cherenkov radiation in spacelike Maxwell-Chern-Simons (MCS) theory is presented. A semiclassical treatment reproduces the leading terms of the tree-le…

Vacuum Cherenkov radiation and photon triple-splitting in a Lorentz-noninvariant extension of quantum electrodynamics
C. Kaufhold, F. R. Klinkhamer
We consider a CPT-noninvariant scalar model and a modified version of quantum electrodynamics with an additional photonic Chern-Simons-like term in the action. In both cases, the L…
