Brownian ratchets: How stronger thermal noise can reduce diffusion
Jakub Spiechowicz, Marcin Kostur, Jerzy Łuczka
We study diffusion properties of an inertial Brownian motor moving on a ratchet substrate, i.e. a periodic structure with broken reflection symmetry. The motor is driven by an unbi…
Comment on 'Absolute negative mobility in a one-dimensional overdamped system'
J. Spiechowicz, M. Kostur, J. Łuczka
Recently Ru-Yin Chen et al. (Phys. Lett. A 379 (2015) 2169-2173) presented results on the absolute negative mobility (ANM) in a one-dimensional overdamped system and claimed that a…
Transport Characteristics of Molecular Motors
Lukasz Machura, Marcin Kostur, Jerzy Luczka
Properties of transport of molecular motors are investigated. A simplified model based on the concept of Brownian ratchets is applied. We analyze a stochastic equation of motion by…
Two coupled Josephson junctions: dc voltage controlled by biharmonic current
L. Machura, J. Spiechowicz, M. Kostur +1
We study transport properties of two Josephson junctions coupled by an external shunt resistance. One of the junction (say, the first) is driven by an unbiased ac current consistin…
Inertial Brownian motors driven by biharmonic signals
Lukasz Machura, Marcin Kostur, Jerzy Luczka
We study transport properties of an inertial Brownian particle moving in viscous symmetric periodic structures and driven by an oscillating signal of two harmonic components. We an…
Arrival time distribution for a driven system containing quenched dichotomous disorder
S. I. Denisov, M. Kostur, E. S. Denisova +1
We study the arrival time distribution of overdamped particles driven by a constant force in a piecewise linear random potential which generates the dichotomous random force. Our a…
