Giant increase of diffusion by small rise of friction
I. G. Marchenko, I. I. Marchenko, V. Aksenova +2
Diffusion coefficient usually decreases when friction increases. We analyze the opposite behavior in the paradigmatic system consisting of an inertial Brownian particle moving in a…

Approach to nonequilibrium: from anomalous to Brownian diffusion via non-Gaussianity
I. G. Marchenko, I. I. Marchenko, J. Åuczka +1
Recent progress in experimental techniques such as single particle tracking allows to analyze both nonequilibrium properties and approach to equilibrium. There are examples showing…

Intriguing properties of transport at the microscales: Langevin equation approach
J. Spiechowicz, J. Åuczka
We present a perspective of simple models of nonequilibrium directed transport described in terms of a Langevin equation formalism. We consider a Brownian particle under various ci…
