Mitigating disorder-induced zero-energy states in weakly-coupled semiconductor-superconductor hybrid systems
Oladunjoye A. Awoga, Martin Leijnse, Annica M. Black-Schaffer +1
Disorder has appeared as one of the main mechanisms to induce topologically trivial zero-energy states in superconductor-semiconductor systems, thereby challenging the detection of…
Zero-frequency supercurrent susceptibility signatures of trivial and topological zero-energy states in nanowire junctions
Lucas Baldo, Luis G. G. V. Dias Da Silva, Annica M. Black-Schaffer +1
We propose a method to distinguish between trivial and topological, Majorana, zero-energy states in both short and long superconductor-normal-superconductor junctions based on Rash…
Bulk Bogoliubov Fermi arcs in non-Hermitian superconducting systems
Jorge Cayao, Annica M. Black-Schaffer
We consider a non-Hermitian superconducting system by coupling a conventional superconductor to a ferromagnet lead and demonstrate the emergence of exceptional points when an exter…
Topological superconductivity enhanced by exceptional points
R. Arouca, Jorge Cayao, Annica M. Black-Schaffer
Majorana zero modes (MZMs) emerge as edge states in topological superconductors and are promising for topological quantum computation, but their detection has so far been elusive.…
Phase-tunable electron transport assisted by odd-frequency Cooper pairs in topological Josephson junctions
Jorge Cayao, Paramita Dutta, Pablo Burset +1
We consider a finite-size topological Josephson junction formed at the edge of a two-dimensional topological insulator in proximity to conventional superconductors and study the im…
