    "abstract": "We show that some classically chaotic quantum systems uncoupled from noisy\nenvironments may generate intrinsic decoherence with all its associated\neffects. In particular, we have observed time irreversibility and high\nsensitivity to small perturbations in the initial conditions in a quasiperiodic\nversion of the kicked rotor. The existence of simple quantum systems with\nintrinsic decoherence clarifies the quantum--classical correspondence in\nchaotic systems.",
