dc.description.abstract
Quasiparticle poisoning and diabatic transitions may significantly narrow the
window for the experimental observation of the 4π-periodic dc Josephson effect
predicted for topological Josephson junctions. Here, we show that switching-
current measurements provide accessible and robust signatures for topological
superconductivity which persist in the presence of quasiparticle poisoning
processes. Such measurements provide access to the phase-dependent subgap
spectrum and Josephson currents of the topological junction when incorporating
it into an asymmetric SQUID together with a conventional Josephson junction
with large critical current. We also argue that pump-probe experiments with
multiple current pulses can be used to measure the quasiparticle poisoning
rates of the topological junction. The proposed signatures are particularly
robust, even in the presence of Zeeman fields and spin-orbit coupling, when
focusing on short Josephson junctions. Finally, we also consider microwave
excitations of short topological Josephson junctions which may complement
switching-current measurements.
