Semi-classical formula beyond the Ehrenfest time in quantum chaos. (I) Trace formula

We consider a nonlinear area preserving Anosov map M on the torus phase space, which is the simplest example of a fully chaotic dynamics. We are interested in the quantum dynamics for long time, generated by the unitary quantum propagator M ^ . The usual semi-classical Trace formula expresses T r M ^ t for finite time t , in the limit 0 , in terms of periodic orbits of M of period t . Recent work reach time t t E / 6 where t E = log ( 1 / ) / λ is the Ehrenfest time, and λ is the Lyapounov coefficient. Using a semi-classical...
