Separation of scales: Dynamical approximations for composite quantum systems
Irene Burghardt, Rémi Carles, Clotilde Fermanian Kammerer +2
We consider composite quantum-dynamical systems that can be partitioned into weakly interacting subsystems, similar to system-bath type situations. Using a factorized wave function…
Adiabatic and non-adiabatic evolution of wave packets and applications to initial value representations
Clotilde Kammerer, Caroline Lasser, Didier Robert
We review some recent results obtained for the time evolution of wave packets for systems of equations of pseudo-differential type, including Schr{ö}dinger ones, and discuss their…
Propagation of Wave Packets for Systems Presenting Codimension 1 Crossings
Clotilde Fermanian-Kammerer, Caroline Lasser, Didier Robert
We analyze the propagation of coherent states through general systems of pseudodifferential form associated with Hamiltonian presenting codimension one eigen-value crossings. In pa…
