Vortex and translational currents due to broken time-space symmetries
S. Denisov, Y. Zolotaryuk, S. Flach +1
We consider the classical dynamics of a particle in a -dimensional space-periodic potential under the influence of time-periodic external fields with zero mean. We perform a…
Resonant fluxon transmission through impurities
Yaroslav Zolotaryuk
Fluxon transmission through several impurities of different strength and type (i.e., microshorts and microresistors), placed in a long Josephson junction is investigated. Threshold…
Discrete soliton ratchets driven by biharmonic fields
Yaroslav Zolotaryuk, Mario Salerno
Directed motion of topological solitons (kinks or antikinks) in the damped and AC-driven discrete sine-Gordon system is investigated. We show that if the driving field breaks certa…
Resonant enhancement of the jump rate in a double-well potential
Y. Zolotaryuk, V. N. Ermakov, P. L. Christiansen
We study the overdamped dynamics of a Brownian particle in the double-well potential under the influence of an external periodic (AC) force with zero mean. We obtain a dependence o…
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…
Simple Mechanical Equivalents of Stepping Rotary Dynamics in F-ATPase
A. V. Zolotaryuk, V. N. Ermakov, P. L. Christiansen +2
Two simple (rotator and one-particle) mechanistic models are suggested to describe simultaneously at a minimal level of sophistication two basic functions of F-ATPase: a motor…
