Divergent beams of nonlocally entangled electrons emitted from hybrid normal-superconducting structures
Elsa Prada, Fernando Sols
We propose the use of normal and Andreev resonances in normal-superconducting structures to generate divergent beams of nonlocally entangled electrons. Resonant levels are tuned to…
Clauser-Horne inequality and decoherence in mesoscopic conductors
Elsa Prada, Fabio Taddei, Rosario Fazio
We analyze the effect of decoherence on the violation of the Clauser-Horne (CH) inequality for the full electron counting statistics in a mesoscopic multiterminal conductor. Our se…
AC Josephson effect in finite-length nanowire junctions with Majorana modes
Pablo San-Jose, Elsa Prada, Ramon Aguado
It has been predicted that superconducting junctions made with topological nanowires hosting Majorana bound states (MBS) exhibit an anomalous 4Ï-periodic Josephson effect. Finding…
Quantum pumping in graphene
Elsa Prada, Pablo San-Jose, Henning Schomerus
We show that graphene-based quantum pumps can tap into evanescent modes, which penetrate deeply into the device as a consequence of Klein tunneling. The evanescent modes dominate p…
Zero-energy pinning from interactions in Majorana nanowires
Fernando DomÃnguez, Jorge Cayao, Pablo San-Jose +3
Majorana zero modes at the boundaries of topological superconductors are charge-neutral, an equal superposition of electrons and holes. This ideal situation is, however, hard to ac…
InP/GaSb core-shell nanowires: a novel hole-based platform with strong spin-orbit coupling for full-shell hybrid devices
Andrea Vezzosi, Carlos Payá, PaweŠWójcik +4
Full-shell hybrid nanowires (NWs), structures comprising a superconductor shell that encapsulates a semiconductor (SM) core, have attracted considerable attention in the search for…
