Radiative corrections arising from Lorentz violation in the fermion sector induce a nonzero amplitude for vacuum photon splitting. At one loop, the on-shell amplitude acquires both CPT-even and CPT-odd contributions forbidden in conventional electrodynamics.

  1. Revisiting Cherenkov radiation in anisotropic chiral matter: exact calculation reveals threshold-free emission

    hep-ph 2026-06 unverdicted novelty 7.0 of 10

    Exact solution of modified Maxwell equations in a position-dependent axion model reveals threshold-free Cherenkov emission for slow charges within specific frequencies, unlike standard materials.

  2. Cherenkov radiation in isotropic chiral matter: the space-frequency domain

    hep-ph 2025-07 conditional novelty 7.0 of 10

    A charge moving through chiral matter radiates Cherenkov light in two independent polarization modes, one of which can radiate at sub-luminal speeds.

  3. Scattering Amplitudes and Resonant Processes in QED with Chiral Chemical Potential and Chiral Magnetic Conductivity

    hep-ph 2026-06 unverdicted novelty 5.0 of 10

    QED scattering amplitudes in a chiral medium with constant μ5 and b0 exhibit resonant behavior in multiple processes, with computed rates for 1→2 processes determining widths of fermion and photon states.
