摘要
We consider microwave spectroscopy of Josephson junctions composed of hybridized Majorana states in topological one-dimensional superconductors. We point out how spectroscopic features of the junction appear in the current phase relation under microwave irradiation. Moreover, we discuss a way to directly probe the nonequilibrium state associated with the 4 pi-periodic Josephson effect. In particular, we show how the microwave driving can be used to switch from a 4 pi to a 2 pi Shapiro step in the current voltage relation.
