An active Lorentz gas: walking droplets in periodic media
Aleksi Majaniemi, Esko Toivonen, Rahil N. Valani +2
The Lorentz gas is a paradigmatic model in dynamical systems theory for understanding the origin of nonequilibrium transport in terms of microscopic deterministic chaos. In the per…
Diffusion in the Inverted Triangular Soft Lorentz Gas
Esko Toivonen, Aleksi Majaniemi, Rainer Klages +1
We investigate diffusion in a two-dimensional inverted soft Lorentz gas, where attractive Fermi-type potential wells are arranged in a triangular lattice. This configuration contra…
Anomalous Diffusion in the Square Soft Lorentz Gas
Esko Toivonen, Joni Kaipainen, Matti Molkkari +3
We demonstrate and analyze anomalous diffusion properties of point-like particles in a two-dimensional system with circular scatterers arranged in a square lattice and governed by…
Asymmetric Roughness of Elastic Interfaces at the Depinning Threshold
Esko Toivonen, Matti Molkkari, Esa Räsänen +1
Roughness of driven elastic interfaces in random media is typically understood to be characterized by a single roughness exponent . We show that at the depinning threshold, due…
