Emergent axion response in multilayered metamaterials
arXiv:2302.05111 · doi:10.1103/PhysRevB.108.115101
Abstract
We consider the design of metamaterials whose behavior embodies the equations of axion electrodynamics. We derive an effective medium description of an assembly of magneto-optical layers with out-of-plane magnetization analytically and show how to achieve effective axion response with tunable parameters. We display some key predictions and validate them numerically.
