Ratchet-like dynamics of fluxons in annular Josephson junctions driven by bi-harmonic microwave fields
A. V. Ustinov, C. Coqui, A. Kemp +2
Experimental observation of the unidirectional motion of a topological soliton driven by a bi-harmonic ac force of zero mean is reported. The observation is made by measuring the c…

High resolution measurements of the switching current in a Josephson tunnel junction: Thermal activation and macroscopic quantum tunneling
A. Wallraff, A. Lukashenko, C. Coqui +2
We have developed a scheme for a high resolution measurement of the switching current distribution of a current biased Josephson tunnel junction using a timing technique. The measu…
