Doubled Shapiro steps in a dynamic axion insulator Josephson junction
Abstract Dynamic axion insulators feature a time-dependent axion field that can be induced by antiferromagnetic resonance. Here, we show that a Josephson junction incorporating this dynamic axion insulator between two superconductors exhibits striking doubled Shapiro steps wherein all odd steps are...
