Abstract

We observe microwave one-way transparency via ultrastrongly-coupled magnetochiral polaritons (MChPs) in a metamolecule with simultaneous breaking of time-reversal and space-inversion symmetries at room temperature. The experimental results are reproduced well via numerical simulations. Effective polarizability tensor analyses of the simulation results verify that the one-way transparency is traced back to massive synthetic motion of MChPs. This study paves a way to hybrid quantum systems and synthetic gauge fields using metamaterials.
