Quantum critical collapse of a pinned vortex glass
David Perconte, Thibault Charpentier, Nikolaos Koutsopoulos +8
The interplay between disorder and vortex--vortex interactions in strongly disordered superconductors in a magnetic field can stabilize a vortex-glass state, characterized by stron…
Chiral-helical junctions in screened graphene
Bilal Kousar, Selma Franca, David Perconte +14
Reproducibility and quantization in quantum spin Hall platforms is a persisting challenge, limiting their use in hybrid realizations of topological superconductivity. We report rob…
Superconductivity in Substitutional Ga-Hyperdoped Ge Epitaxial Thin Films
Julian A. Steele, Patrick J. Strohbeen, Carla Verdi +12
Doping-induced superconductivity in group IV elements may enable quantum functionalities in material systems accessible with well-established semiconductor technologies. Non-equili…
The feedback driven atomic scale Josephson microscope
Samuel D. Escribano, VÃctor Barrena, David Perconte +10
The ultimate spatial limit to establish a Josephson coupling between two superconducting electrodes is an atomic-scale junction. The Josephson effect in such ultrasmall junctions h…
