Non-ergodicity and localization of invariant measure for two colliding masses
Jiao Wang, Giulio Casati, Tomaz Prosen
We show evidence, based on extensive and carefully performed numerical experiments, that the system of two elastic hard-point masses in one-dimension is not ergodic for a generic m…

Time irreversible billiards with piecewise-straight trajectories
Giulio Casati, Tomaz Prosen
We introduce a new family of billiards which break time reversal symmetry in spite of having piece-wise straight trajectories. We show that our billiards preserve the ergodic and m…
