Abstract
Using the kicked rotator as an example, we show how to apply the formalism of Wigner symbols to the study of quantum dynamics. This approach provides a simple and direct method of comparing quantum and classical dynamics. We investigate in detail the leading quantum effects for small values of ħ and discuss the time scales at which quantum effects appear.Keywords
