Covariant Quantization of CPT-violating Photons
D. Colladay, P. McDonald, J. P. Noordmans +1
We perform the covariant canonical quantization of the CPT- and Lorentz-symmetry-violating photon sector of the minimal Standard-Model Extension, which contains a general (timelike…
CPT-Violating, Massive Photons and Cherenkov Radiation
Don Colladay
CPT-Violating photons are well-known to have problems with energy positivity in certain cases and therefore have not been convincingly quantized to date. We find that by adding a s…
Torsional Rigidity, Isospectrality and Quantum Graphs
Don Colladay, Leon Kaganovskiy, Patrick McDonald
We study torsional rigidity for graph and quantum graph analogs of well-known pairs of isospectral non-isometric planar domains. We prove that such isospectral pairs are distinguis…
Cherenkov Radiation with Massive, CPT-violating Photons
Don Colladay, Patrick McDonald, Robertus Potting
The source of CPT-violation in the photon sector of the Standard Model Extension arises from a Chern-Simons-like contribution that involves a coupling to a fixed background vector…
