Absence of Quasi-Majorana False Positives in Full-Shell Hybrid Nanowires
Carlos Payá, César Robles, Pablo San-Jose +1
Tunneling spectroscopy cannot be used as an unambiguous detection tool for Majorana zero modes (MZMs) in conventional partial-shell nanowires. The presence of smooth confinement at…
Non-Hermitian skin effect and electronic nonlocal transport
Carlos Payá, Oliver Solow, Elsa Prada +2
Open quantum systems governed by non-Hermitian effective Hamiltonians exhibit unique phenomena, such as the non-Hermitian skin effect, where eigenstates localize at system boundari…
Fluxoid valve effect in full-shell nanowire Josephson junctions
Carlos Payá, F. J. Matute-Cañadas, A. Levy Yeyati +3
We introduce a new type of supercurrent valve based on full-shell nanowires. These hybrid wires consist of a semiconductor core fully wrapped in a thin superconductor shell and sub…
Josephson effect and critical currents in trivial and topological full-shell hybrid nanowires
Carlos Payá, Ramón Aguado, Pablo San-Jose +1
We perform microscopic numerical simulations of the Josephson effect through short junctions between two full-shell hybrid nanowires, comprised of a semiconductor core fully wrappe…
