Pseudo-classical theory for fidelity of nearly resonant quantum rotors
arXiv:0907.0610 · doi:10.1103/PhysRevE.80.035206
Abstract
Using a semiclassical ansatz we analytically predict for the fidelity of delta-kicked rotors the occurrence of revivals and the disappearance of intermediate revival peaks arising from the breaking of a symmetry in the initial conditions. A numerical verification of the predicted effects is given and experimental ramifications are discussed.
