Probing emergent axion electrodynamics with waveguide apparatus

Abstract

We demonstrate that a conventional hollow conductor waveguide filled with a material exhibiting the coexistence of chiral magnetic and anomalous quantum Hall effects supports the propagation of transverse electromagnetic modes. This simple setup provides a direct and optically feasible method to probe the simultaneous presence of these phenomena, potentially enabling the detection of an emergent axion-like field within condensed matter systems.

Minor improvements for clarity
