Finite Length Effects and Coulomb Interaction in Ge Quantum Well-Based Josephson Junctions Probed with Microwave Spectroscopy
S. C. ten Kate, D. C. Ohnmacht, M. Coraiola +10
Proximitized Ge quantum wells have emerged as a novel platform for studying Andreev bound states (ABSs), due to their expected strong spin-orbit interaction and high mobility. Here…

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…

Development of a Nb-based semiconductor-superconductor hybrid platform
Sjoerd Telkamp, Tommaso Antonelli, Clemens Todt +12
Semiconductor-superconductor hybrid materials are used as a platform to realise Andreev bound states, which hold great promise for quantum applications. These states require transp…
