Nonergodicity and localization of invariant measure for two colliding masses
Nonergodicity and localization of invariant measure for two colliding masses
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 mass ratio and consequently does not follow the principle of energy equipartition. This system is equivalent to a right triangular billiard. Remarkably, following …
