    "abstract": "We discuss the dephasing induced by the internal classical chaotic motion in\nthe absence of any external environment. To this end we consider a suitable\nextension of fidelity for mixed states which is measurable in a Ramsey\ninterferometry experiment. We then relate the dephasing to the decay of this\nquantity which, in the semiclassical limit, is expressed in terms of an\nappropriate classical correlation function. Our results are derived\nanalytically for the example of a nonlinear driven oscillator and then\nnumerically confirmed for the kicked rotor model.",
