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…
Semiclassical quantization of maps with a variable time scale
A. Iomin, S. Fishman, G. M. Zaslavsky
Quantization of energy balance equations, which describe a separatrix -- like motion is presented. The method is based on an exact canonical transformation of the energy--time pair…
Relaxation and Noise in Chaotic Systems
Shmuel Fishman, Saar Rahav
For a class of idealized chaotic systems (hyperbolic systems) correlations decay exponentially in time. This result is asymptotic and rigorous. The decay rate is related to the Rue…
A Theory for Quantum Accelerator Modes in Atom Optics
Shmuel Fishman, Italo Guarneri, Laura Rebuzzini
Unexpected accelerator modes were recently observed experimentally for cold cesium atoms when driven in the presence of gravity. A detailed theoretical explanation of this quantum…
