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…
Formation, prevalence, and stability of bouncing-ball quantum scars
Simo Selinummi, Joonas Keski-Rahkonen, Fartash Chalangari +1
Quantum scars correspond to enhanced probability densities along unstable classical periodic orbits. In recent years, research on quantum scars has extended to various systems incl…
Chaotic dynamics creates and destroys branched flow
Alexandre Wagemakers, Aleksi Hartikainen, Alvar Daza +2
The phenomenon of branched flow, visualized as a chaotic arborescent pattern of propagating particles, waves, or rays, has been identified in disparate physical systems ranging fro…
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…
