We study the dynamics of superposed wave packets in a specific nonlinear Hamiltonian which models the wave packet propagation in Kerr-like media and the dynamics of Bose–Einstein condensates. We show the dependence of fractional revival times on the initial superposed wave packets using analysis based on the expectation values, Renyi entropy and Wigner function. We also show how the selective identification of fractional revivals using moments of appropriate observables depends on the number of… CONTINUE READING
