    "abstract": "We discuss the dephasing induced by the internal classical chaotic motion in\nthe absence of any external environment. To this end a new extension of\nfidelity for mixed states is introduced, which we name {\\it allegiance}. Such\nquantity directly accounts for quantum interference and is measurable in a\nRamsey interferometry experiment. We show that in the semiclassical limit the\ndecay of the allegiance is exactly expressed, due to the dephasing, in terms of\nan appropriate classical correlation function. Our results are derived\nanalytically for the case of a nonlinear driven oscillator and then numerically\nconfirmed for the kicked rotor model.",
