Perfect Nonreciprocal Axion-polaritons
Under appropriate static electric (E₀ ‖ ŷ) and magnetic (B₀ ‖ ẑ) fields applied simultaneously to a dynamical axion insulator, axion-polaritons — hybrid axion-photon collective modes — acquire a nonreciprocal dispersion ω(k) ≠ ω(−k). This arises because the axion-photon coupling is direction-dependent: photons propagating in opposite directions hybridize with the axion with different strengths (g₊ ≠ g₋). Neither field alone is sufficient; the simultaneous breaking of inversion symmetry (by E₀) and time-reversal symmetry (by B₀) produces the term 2𝓔𝓑kω in the quartic dispersion (Eq. 4) that…
