Abstract: Shapiro steps are quantized plateaus in the velocity-force or velocity-torque curve of a driven system, when its speed remains constant despite an increase in the driving force. For microscopic particles driven across a sinusoidal potential,… read more here.

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.
