Probing Synthetic Caroli-de Gennes-Matricon States Through Critical Current in Full-Shell Nanowire Josephson Junctions
Carlos Payá, Ãngel Ibabe, Mario Gómez +6
Full-shell hybrid nanowires consisting of a semiconductor core fully enveloped by a superconducting shell have emerged as a platform to study Caroli-de Gennes-Matricon (CdGM) analo…
Valley Valves at Domain Walls in Symmetry-Broken Rhombohedral Graphene
Vo Tien Phong, Francisco Lobo, Elsa Prada +3
Rhombohedral multilayer graphene polarized by a moderate perpendicular displacement field hosts a time-reversal-symmetry-breaking valley-and-spin-polarized metallic phase that may…
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…
Solitonic Andreev spin qubits from Andreev states in Corbino Josephson junctions
Pablo San-Jose, Elsa Prada
We study a novel type of solitonic Andreev bound state (ABS) in a Corbino-geometry Josephson junction created on a 2DEG. The Josephson junction is subjected to a weak magnetic flux…
Fluxoid solitons in superconducting tapered tubes and bottlenecks
Tim Kokkeler, Mateo Uldemolins, Francisco Lobo +3
A thin-walled tubular superconductor develops a quantized fluxoid in the presence of an axial magnetic field. The fluxoid corresponds to the number of phase windings of the superco…
