On the inclusion of dissipative effects in clusters and molecules
Speaker:Eric Suraud (Université Paul Sabatier, Toulouse 3)
Abstract:Mean field provides an essential starting point to understand the dynamics of numerous many-body systems ranging from nuclei to molecules, clusters and nanostructures. Recent developments in laser technology now allow to analyse the response of clusters and molecules in short intense laser fields which typically lead to dissipative effects beyond mean field. We discuss studies we have performed to include incoherent correlations on top of Time Dependent LDA or Time Dependent Hartree Fock (TDHF) approaches which represent archetypical approaches in the time domain. We discuss two new developments: The quantum Relaxation Time Ansatz (RTA) providing an approximate quantum kinetic treatment [6] and the stochastic extension of mean field known as Stochastic TDHF. We present applications to simple molecular systems.
