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…
Local and Non-local Microwave Impedance of a Three-Terminal Hybrid Device
B. Harlech-Jones, S. J. Waddy, J. D. S. Witt +8
We report microwave impedance measurements of a superconductor-semiconductor hybrid nanowire device with three terminals (3T). Our technique makes use of transmission line resonato…
InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Gate-Tunable Transmon Using Selective-Area-Grown Superconductor-Semiconductor Hybrid Structures on Silicon
A. Hertel, M. Eichinger, L. O. Andersen +12
We present a gate-voltage tunable transmon qubit (gatemon) based on planar InAs nanowires that are selectively grown on a high resistivity silicon substrate using III-V buffer laye…
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…
