Non-ergodicity induced by isotropic random perturbation.
We present a two-well Hamiltonian system in which isotropic random perturbation induces non-ergodic behavior where orbits tend to spend more time in one of two wells. It is numerically shown that this behavior is due to the difference in its orbital separation rates near the exits of wells.
