Link between supercurrent diode and anomalous Josephson effect revealed by gate-controlled interferometry

Simon Reinhardt, Tim Ascherl, Andreas Costa +9

In Josephson diodes the asymmetry between positive and negative current branch of the current-phase relation leads to a polarity-dependent critical current and Josephson inductance…

Sharpness of the Berezinskii-Kosterlitz-Thouless transition in ultrathin NbN films

Alexander Weitzel, Lea Pfaffinger, Ilaria Maccari +8

We present a comprehensive investigation of the Berezinskii-Kosterlitz-Thouless (BKT) transition in ultrathin strongly disordered NbN films. Measurements of resistance, current-vol…

Sign reversal of the AC and DC supercurrent diode effect and 0--like transitions in ballistic Josephson junctions

Andreas Costa, Christian Baumgartner, Simon Reinhardt +9

The recent discovery of intrinsic supercurrent diode effect, and its prompt observation in a rich variety of systems, has shown that nonreciprocal supercurrents naturally emerge wh…

Supercurrent interference in HgTe Josephson junctions

Wolfgang Himmler, Ralf Fischer, Michael Barth +8

Wires made of topological insulators (TI) are a promising platform for searching for Majorana bound states. These states can be probed by analyzing the fractional ac Josephson effe…

Non-reciprocity of Vortex-limited Critical Current in Conventional Superconducting Micro-bridges

Dhavala Suri, Akashdeep Kamra, Thomas N. G. Meier +4

Non-reciprocity in the critical current has been observed in a variety of superconducting systems and has been called the superconducting diode effect. The origin underlying the ef…

Effect of Rashba and Dresselhaus spin-orbit coupling on supercurrent rectification and magnetochiral anisotropy of ballistic Josephson junctions

Christian Baumgartner, Lorenz Fuchs, Andreas Costa +11

Simultaneous breaking of inversion- and time-reversal symmetry in Josephson junction leads to a possible violation of the equality for the current-phase relation. Thi…
