Description
Effects of contraction in the description of a two-level quantum system coupled to a classical electromagnetic field are studied. Different observation levels are introduced and the corresponding nonlinear equations of motion are obtained. The solutions are discussed with respect to stability, constants of motion and evolution of relevant entropies. (orig.)
