We investigate a ballistic InSb nanoflag-based Josephson junction with Nb superconducting contacts. The high transparency of the superconductor-semiconductor interfaces enables …
In superconducting systems in which inversion and time-reversal symmetry are simultaneously broken the critical current for positive and negative current bias can be …
When a Josephson junction is exposed to microwave radiation, it undergoes the inverse AC Josephson effect─ the phase of the junction locks to the drive frequency. As a result, the I–V …

In this paper, in an in situ prepared three-terminal Josephson junction based on the topological insulator Bi 4 Te 3 and the superconductor Nb the transport properties are …
In the presence of a 4π-periodic contribution to the current phase relation, for example in topological Josephson junctions, odd Shapiro steps are expected to be missing. While …
We study numerically the fractional Shapiro step response in low-frequency driven Josephson junctions which have a nonsinusoidal current-phase relation. We perform this …
