DOI: 10.1007/s10948-016-3642-8
Abstract: The coherent nonlinear dynamics of Abrikosov vortices in asymmetric pinning nanolandscapes is studied by theoretical modeling and combined microwave and dc electrical resistance measurements. The problem is considered on the basis of a single-vortex Langevin… read more here.

DOI: 10.1021/acsnano.2c10880
Abstract: In the presence of a 4π-periodic contribution to the current phase relation, for example in topological Josephson junctions, odd Shapiro steps are expected to be missing. While missing odd Shapiro steps have been observed in… read more here.

DOI: 10.1103/physrevb.104.054521
Abstract: It is widely believed that superconducting junctions involving topological insulators and hosting Majorana-like bound states may exhibit unusual ”fractional” (4π-periodic) ac Josephson effect. Accordingly, ”fractional” Shapiro steps on the current-voltage characteristics of such junctions are… read more here.

DOI: 10.1103/physrevb.98.014525
Abstract: Bloch oscillations in a single Josephson junction in the phase-slip regime relate current to frequency. They can be measured by applying a periodic drive to a DC-biased, small Josephson junction. Phase-locking between the periodic drive… read more here.
