Bb. Hu et al., SQUEEZED STATE DYNAMICS OF KICKED QUANTUM-SYSTEMS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 58(2), 1998, pp. 1743-1756
We study kicked quantum systems by using the squeezed state approach.
Taking the kicked quantum harmonic oscillator as an example, we demons
trate that chaos in an underlying classical system can be enhanced as
well as suppressed by quantum fluctuations. Three different energy dif
fusions are observed in the kicked quantum harmonic oscillator, namely
, localization, linear diffusion, and quadratic diffusion.
