Linearized survival probability for revivals in a Morse oscillator — •Sreeja Loho Choudhury and Frank Grossmann — Institut für Theoretische Physik, Technische Universität Dresden, D-01062 Dresden, Germany

We extend the Husimi (coherent state) based version of linearized semiclassical theories [1] for the calculation of correlation functions to the case of survival probabilities. This is a case that could be dealt with before only by use of the Wigner version of linearized semiclassical theory [2, 3]. Numerical comparisons of the Husimi and the Wigner case with full quantum results as well as with full semiclassical ones will be given for the revival dynamics in a Morse oscillator with and without coupling to an additional harmonic degree of freedom.
