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…
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…
Nonlocal conductance spectroscopy of Andreev bound states in gate-defined InAs/Al nanowires
Andreas Pöschl, Alisa Danilenko, Deividas Sabonis +5
The charge character of Andreev bound states (ABSs) in a three-terminal semiconductor-superconductor hybrid nanowire was measured using local and nonlocal tunneling spectroscopy. T…
Measurements of cyclotron resonance of the interfacial states in strong spin-orbit coupled 2D electron gases proximitized with aluminum
Prashant Chauhan, Candice Thomas, Tyler Lindemann +4
Two-dimensional electron gasses (2DEG) in InAs quantum wells proximitized by aluminum are promising platforms for topological qubits based on Majorana zero modes. However, there ar…
Nonlocal signatures of hybridization between quantum dot and Andreev bound states
Andreas Pöschl, Alisa Danilenko, Deividas Sabonis +5
We investigate local and nonlocal signatures of hybridization between a quantum dot state and an extended Andreev bound state (ABS) in a gate-defined InAs nanowire with multiple si…
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…
