Nonreciprocal Equilibrium Josephson Effect of Arbitrary Periodicity from Poor Man's Majorana Zero Modes
Panagiotis Kotetes, Mercè Roig, Brian M. Andersen
We show that the Josephson diode effect becomes possible when two coupled antiferromagnetic dimers of point-like magnetic adatoms are deposited on top of a Rashba superconductor. T…

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…
