The Gross Pitaevski map as a chaotic dynamical system
Italo Guarneri
The Gross Pitaevski map is a discrete time, split operator version of the Gross Pitaevski dynamics in the circle, for which exponential instability has been recently reported. Here…
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…
Effects of atomic interactions on Quantum Accelerator Modes
Laura Rebuzzini, Roberto Artuso, Shmuel Fishman +1
We consider the influence of the inclusion of interatomic interactions on the delta-kicked accelerator model. Our analysis concerns in particular quantum accelerator modes, namely…
A classical scaling theory of quantum resonances
Sandro Wimberger, Italo Guarneri, Shmuel Fishman
The quantum resonances occurring with delta-kicked particles are studied with the help of a fictitious classical limit, establishing a direct correspondence between the nearly reso…
Quantum resonances and decoherence for delta-kicked atoms
Sandro Wimberger, Italo Guarneri, Shmuel Fishman
The quantum resonances occurring with delta-kicked atoms when the kicking period is an integer multiple of the half-Talbot time are analyzed in detail. Exact results about the mome…
