Exact hopping and collision times for two hard discs in a box
Wilhelm P. K. Zapfe, David P. Sanders, Rosa Rodríguez-Mota
We study the molecular dynamics of two discs undergoing Newtonian ("inertial") dynamics, with elastic collisions in a rectangular box. Using a mapping to a billiard model and a key…
Local quantum ergodic conjecture
E. Zambrano, W. P. Karel Zapfe, Alfredo M. Ozorio de Almeida
The Quantum Ergodic Conjecture equates the Wigner function for a typical eigenstate of a classically chaotic Hamiltonian with a delta-function on the energy shell. This ensures the…
The chaotic set and the cross section for chaotic scattering beyond in 3 degrees of freedom
C. Jung, O. Merlo, T. H. Seligman +1
This article treats chaotic scattering with three degrees of freedom, where one of them is open and the other two are closed, as a first step toward a more general understanding of…
About Imperfect Mushroom Billiards
W. P. Karel Zapfe, Francois Leyvraz, Thomas H. Seligman
Imperfections of Bunimovich mushroom Billiards are analyzed. Any experiment will be affected by such imperfections, and it will be necessary to estimate their influence. In particu…
