Origin of the superconductor-insulator transition in disordered two-dimensional films
Alexander Weitzel, Lea Pfaffinger, Animesh Panda +8
Theory predicts the superconductor-to-insulator transition (SIT) to emerge from the competition between Anderson localization, which tends to localize single-particle wavefunctions…
Emergence of Bogoliubov Fermi Surfaces in hybrid Al/InAs heterostructures
S. Feyrer, V. Dimic, I. Lobato +15
We investigate the microwave electrodynamics of a proximitized two-dimensional electron gas in hybrid superconductor/semiconductor heterostructures. Using lumped-element resonators…
Magneto-Chiral Anisotropy in Josephson Diode Effect of All-Metallic Lateral Junctions with Interfacial Rashba Spin-Orbit Coupling
Maximilian Mangold, Lorenz Bauriedl, Johanna Berger +7
We explore the role of interfacial Rashba spin-orbit coupling (SOC) for the Josephson diode effect in all-metal diffusive Josephson junctions. Devices with Fe/Pt and Cu/Pt weak lin…
Giant anomalous Josephson effect as a probe of spin texture in topological insulators
Niklas Hüttner, Andreas Costa, Leandro Tosi +9
Surface states of topological insulators feature chiral spin-momentum locking. When such states are used as weak link between two superconductors, their spin texture gives rise to…
Antichiral edge states and Bogoliubov Fermi surfaces in a two-dimensional proximity-induced superconductor
Gabriel F. RodrÃguez Ruiz, Juan Herrera Mateos, Leandro Tosi +3
We show that a magnetic field parallel to the plane of a two-dimensional electron gas with Rashba spin orbit coupling in proximity to a superconductor leads to a topological phase…
Spontaneous supercurrents and vortex depinning in two-dimensional arrays of -junctions
Simon Reinhardt, Alexander-Georg Penner, Johanna Berger +9
Two-dimensional arrays of ballistic Josephson junctions are important as model systems for synthetic quantum materials. Here, we investigate arrays of multiterminal junctions which…
