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…
Anisotropic vortex squeezing in synthetic Rashba superconductors: a manifestation of Lifshitz invariants
Lorenz Fuchs, Denis Kochan, Christian Baumgartner +7
Most of 2D superconductors are of type II, i.e., they are penetrated by quantized vortices when exposed to out-of-plane magnetic fields. In presence of a supercurrent, a Lorentz-li…
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…
Supercurrent diode effect and magnetochiral anisotropy in few-layer NbSe
Lorenz Bauriedl, Christian Bäuml, Lorenz Fuchs +9
Nonreciprocal transport refers to charge transfer processes that are sensitive to the bias polarity. Until recently, nonreciprocal transport was studied only in dissipative systems…
A Josephson junction supercurrent diode
Christian Baumgartner, Lorenz Fuchs, Andreas Costa +10
Transport is called nonreciprocal when not only the sign, but also the absolute value of the current, depends on the polarity of the applied voltage. It requires simultaneously bro…
Josephson inductance as a probe for highly ballistic semiconductor-superconductor weak links
Christian Baumgartner, Lorenz Fuchs, Linus Frész +6
We present simultaneous measurements of Josephson inductance and DC transport characteristics of ballistic Josephson junctions based upon an epitaxial Al-InAs heterostructure. The…
