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…

Temperature anomalies of oscillating diffusion in ac-driven periodic systems
I. G. Marchenko, V. Aksenova, I. I. Marchenko +2
We analyse the impact of temperature on the diffusion coefficient of an inertial Brownian particle moving in a symmetric periodic potential and driven by a symmetric time-periodic…
