From Shapiro steps to photon-assisted tunneling in microwave-driven atomic-scale Josephson junctions with a single (magnetic) adatom
Martina Trahms, Bharti Mahendru, Clemens B. Winkelmann +1
Ultra-small Josephson junctions are strongly influenced by noise and damping due to energy dissipation into the environment, which are expected to suppress phase coherence. Here, w…

Superconductivity of alpha-gallium probed on the atomic scale by normal and Josephson tunneling
C. Fohn, D. Wander, D. Nikolic +6
We investigate superconducting gallium in its phase using scanning tunneling microscopy and spectroscopy at temperatures down to about 100 mK. High-resolution tunneling spectro…
