Exploring the energy spectrum of a four-terminal Josephson junction: Towards topological Andreev band structures
Tommaso Antonelli, Marco Coraiola, David Christian Ohnmacht +10
Hybrid multiterminal Josephson junctions (JJs) are expected to harbor a novel class of Andreev bound states (ABSs), including topologically nontrivial states in four-terminal devic…

Direct microwave spectroscopy of Andreev bound states in planar Ge Josephson junctions
M. Hinderling, S. C. ten Kate, M. Coraiola +7
We demonstrate microwave measurements of the Andreev bound state (ABS) spectrum in planar Josephson junctions (JJs) defined in Ge high mobility two-dimensional hole gases contacted…

Flux-Tunable Josephson Diode Effect in a Hybrid Four-Terminal Josephson Junction
M. Coraiola, A. E. Svetogorov, D. Z. Haxell +10
We investigate the direction-dependent switching current in a flux-tunable four-terminal Josephson junction defined in an InAs/Al two-dimensional heterostructure. The device exhibi…
