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…

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…

Exponential suppression of the topological gap in self-consistent intrinsic Majorana nanowires
Francisco Lobo, Elsa Prada, Pablo San-Jose
Predictions of topological p-wave superconductivity and Majorana zero modes (MZMs) in hybrid superconductor-semiconductor nanowires have been difficult to realize experimentally. C…
