    "abstract": "Chaotic evolutions exhibit exponential sensitivity to initial conditions.\nThis suggests that even very small perturbations resulting from weak coupling\nof a quantum chaotic environment to the position of a system whose state is a\nnon-local superposition will lead to rapid decoherence. However, it is also\nknown that quantum counterparts of classically chaotic systems lose exponential\nsensitivity to initial conditions, so this expectation of enhanced decoherence\nis by no means obvious. We analyze decoherence due to a \"toy\" quantum\nenvironment that is analytically solvable, yet displays the crucial phenomenon\nof exponential sensitivity to perturbations. We show that such an environment,\nwith a single degree of freedom, can be far more effective at destroying\nquantum coherence than a heat bath with infinitely many degrees of freedom.\nThis also means that the standard \"quantum Brownian motion\" model for a\ndecohering environment may not be as universally applicable as it once was\nconjectured to be.",
