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…
Exponential Quantum Spreading in a Class of Kicked Rotor Systems near High-Order Resonances
Hailong Wang, Jiao Wang, Italo Guarneri +2
Long-lasting quantum exponential spreading was recently found in a simple but very rich dynamical model, namely, an on-resonance double-kicked rotor model [J. Wang, I. Guarneri, G.…
Long-lasting Exponential Spreading in Periodically Driven Quantum Systems
Jiao Wang, Italo Guarneri, Giulio Casati +1
Using a dynamical model relevant to cold-atom experiments, we show that long-lasting exponential spreading of wave packets in momentum space is possible. Numerical results are expl…
