Gapless superconductivity from extremely dilute magnetic disorder in 2H-NbSe2-xSx
Jose Antonio Moreno, Mercè Roig, VÃctor Barrena +14
Most superconducting materials exhibit a vanishing density of states at the Fermi level and Anderson's theorem posits that the superconducting gap is robust against nonmagnetic dis…

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…
