François David, IPhT Saclay:
Random matrix ensembles for quantum decoherence
I present a class of random matrix ensembles relevant for the study of quantum decoherence for quantum spins. These ensembles generalize the standard GUE ensemble. For a single spin j, they lead to exact solutions for the dynamics of decoherence and for quantum diffusion. I discuss the general non-markovian case, the markovian limits and the quantum-to-classical transition.
