Analog event horizons from magnetoelectric materials
arXiv:2205.05149
Abstract
Analog models of gravity provide a laboratory setting to investigate curved space phenomena. In this context, linear magnetoelectric materials offer interesting possibilities for modeling such analog geometries. Here, general conditions under which a light ray enters a one-way (trapped) region, bounded by an analog event horizon, are identified. The results, thereby, establish linear magnetoelectric materials as a new platform for analog black hole physics.
