Fast Josephson vortex ratchet made of intrinsic Josephson junctions inBi2Sr2CaCu2O8

Electrothermal behavior and terahertz emission properties of a planar array of two Bi2Sr2CaCu2O8+δintrinsic Josephson junction stacks

“…The setup for LTSLM is described in [56]. In brief, the beam of a laser diode is focused and scanned across the sample surface.…”

ModelI–Vcurves and figures of merit of underdamped deterministic Josephson ratchets

“…Such deterministic ratchets find many applications as rectifiers, sorters, etc.. Deterministic and stochastic ratchets have been in the focus of attention during the last two decades in various implementations. In particular, Josephson systems based on the motion of Josephson vortices [6][7][8][9][10][11][12][13][14][15] or the Josephson phase [16][17][18][19][20][21] have been suggested and tested experimentally.…”

TunableφJosephson junction ratchet

“…Apart from answering some fundamental questions, they can be immediately employed for the extraction of work out of nonequilibrium thermal fluctuations, for rectification of deterministic signals, or for particle separation [1][2][3][4]. Apart from the ratchets existing in nature [5], there are plenty of artificial ratchet implementations, in particular, based on nanostructured superconductors: Josephson vortex ratchets [6][7][8][9][10][11][12][13][14][15][16], SQUID ratchets [17][18][19][20][21][22][23] and Abrikosov vortex ratchets [24,25].…”
