Subdiffusion via dynamical localization induced by thermal equilibrium fluctuations
Jakub Spiechowicz, Jerzy Łuczka
We reveal the mechanism of subdiffusion which emerges in a straightforward, one dimensional classical nonequilibrium dynamics of a Brownian ratchet driven by both a time-periodic f…
Negative mobility of a Brownian particle: strong damping regime
Aleksandra Słapik, Jerzy Łuczka, Jakub Spiechowicz
We study impact of inertia on directed transport of a Brownian particle under non-equilibrium conditions: the particle moves in a one-dimensional periodic and symmetric potential,…
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…
