We calculate the induced Lorentz- and CPT-violating Chern-Simons term arising from the Lorentz- and CPT-violating sector of quantum electrodynamics with a $b_\mu\bar{\psi}\gamma^\mu\gamma_5\psi$ term. The result to all orders in $b$ coincides with the previous linear-in-$b$ calulation by Chung and Oh [hep-th/9812132] as well as Jackiw and Kosteleck\'{y} [Phys. Rev. Lett. {\bf 82}, 3572 (1999)], since all higher order terms vanish.

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

    hep-th 2026-06 unverdicted novelty 4.0

    One-loop calculation in LV scalar QED with nonminimal coupling shows photon two-point function remains transverse due to diagram cancellations, preserving gauge invariance.
