Can the Brownian diffusion coefficient be reconstructed from Lyapunov exponents?
I. G. Marchenko, I. I. Marchenko, D. Ivashchenko +2
We consider an ac-driven particle moving in a spatially periodic and symmetric potential. In the zero- temperature limit, for the analyzed parameter set, its dynamics is non-chaoti…

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…
