    "abstract": "We examine the dynamics of a wave packet that initially corresponds to a\ncoherent state in the model of quantum kicked rotator. This main model of\nquantum chaos, which allows for a transition from regular to to chaotic\nbehavior in the classical limit, may be realized in experiments with cold\natoms. We study the generation of squeezed states in the quasiclassical limit\nand in a time interval when quantum-classical correspondence is yet\nwell-defined. We find that the degree of squeezing depends on the degree of\nlocal instability in the system and increases with the Chirikov parameter of\nstochasticity. We discuss the dependence of the degree of squeezing on the\ninitial width of the packet, the problems of stability and observability of\nsqueezed states at the transition to quantum chaos, as well as the dynamics of\nwave packet destruction.",
