Limits on the Carroll-Field-Jackiw electrodynamics from geomagnetic data

G. F. de Carvalho, M. Fillion, P. C. Malta +1

Lorentz-symmetry violation may be described via the CPT-odd, dimension-3, Carroll-Field-Jackiw term, which couples the electromagnetic fields to a constant 4-vector $k_{\mathrm{AF}}$ se…
