In a nonperturbative formulation, radiative corrections arising from Lorentz and CPT violation in the fermion sector induce a definite and nonzero Chern-Simons addition to the electromagnetic action. If instead a perturbative formulation is used, an infinite class of theories characterized by the value of the Chern-Simons coefficient emerges at the quantum level.

  1. Crystallography, Lorentz violation, and the Standard-Model Extension

    cond-mat.mes-hall 2026-04 unverdicted novelty 6.0

    Crystal point groups parametrize SME Lorentz-violating coefficients in electromagnetic media, turning birefringent and multiferroic crystals into analogs for high-energy symmetry violations.

  2. Perturbative Analysis of CPT-Odd Lorentz-Violating Scalar QCD

    hep-th 2026-05 unverdicted novelty 5.0

    CPT-odd Lorentz-violating scalar QCD is multiplicatively renormalizable at one loop, with all divergences absorbed into existing counterterms and explicit beta functions obtained.
