Coupling Right- and Left-Handed Photons Differently to Charged Matter
Brett Altschul
We consider a modification of electrodynamics in which right- and left-circularly polarized photons are coupled to charged sources differently. Even though photon helicity is a Lor…
Lorentz and CPT Violation in Scalar-Mediated Potentials
Brett Altschul
In Lorentz- and CPT-violating effective field theories involving scalar and spinor fields, there exist forms of Lorentz violation that modify only the scalar-spinor Yukawa interact…
Quantum Effects of a Spacetime Varying alpha on the Propagation of Electrically Charged Fermions
Alejandro Ferrero, Brett Altschul
A spacetime-varying fine structure constant alpha(x^mu) could generate quantum corrections in some of the coefficients of the Lorentz-violating standard model extension (SME) assoc…
Lorentz Violation and the Higgs Mechanism
Brett Altschul
We consider scalar quantum electrodynamics in the Higgs phase and in the presence of Lorentz violation. Spontaneous breaking of the gauge symmetry gives rise to Lorentz-violating g…
