Quantum crossover in moderately damped epitaxial NbN/MgO/NbN junctions with low critical current density
Luigi Longobardi, Davide Massarotti, Giacomo Rotoli +6
High quality epitaxial NbN/MgO/NbN Josephson junctions have been realized with MgO barriers up to a thickness of d=1 nm. The junction properties coherently scale with the size of b…

Thermal hopping and retrapping of a Brownian particle in the tilted periodic potential of a NbN/MgO/NbN Josephson junction
Luigi Longobardi, Davide Massarotti, Giacomo Rotoli +6
We report on the occurrence of multiple hopping and retrapping of a Brownian particle in a tilted washboard potential. The escape dynamic has been studied experimentally by measuri…
