Characterizing a transition from limited to unlimited diffusion in energy for a time-dependent billiard
Felipe Augusto O. Silveira, Anne Kétri P. da Fonseca, Peter Schmelcher +2
We explore Fermi acceleration in a driven oval billiard which shows unlimited to limited diffusion in energy when passing from the free to the dissipative case. We provide evidence…

Scaling of the dynamical properties of the Fermi-Ulam accelerator model
Denis Gouvêa Ladeira, Jafferson Kamphorst Leal da Silva
The chaotic sea below the lowest energy spanning curve of the complete Fermi-Ulam model (FUM) is numerically investigated when the amplitude of oscillation 'epsilon' of the moving…
