Fractional Josephson effect is a unique character of Majorana Fermions in topological superconductor system. This effect is very difficult to detect experimentally because of the disturbance of quasiparticle poisoning and unwanted couplings in the superconductor. Here, we propose a scheme to probe fractional DC Josephson effect of semiconductor nanowire-based topological Josephson junction through 4{\pi} phase slip. By exploiting a topological RF SQUID system we find that the dominant… Expand

Revisiting 2π phase slip suppression in topological Josephson junctions
Current state of the art devices for detecting and manipulating Majorana fermions commonly consist of networks of Majorana wires and tunnel junctions. We study a key ingredient of these networks - aExpand

This work uses microwave spectra to distinguish Majorana bound states (MBSs) from topological trivial Andreev bound states and finds that the two kinds of bound states have distinct responses to variations in the related parameters. Expand
