Abstract

The visit of Prof. Paul A. Pearce, for the period of 30 day, will start a collaboration with the local group. Prof. Pearce is an expert in exact integrable models and applications of conformal invariance in statistical mechanics. The entanglement entropies of quantum chains associated to conformal invariant non unitary models will be studied. During the visit, we also intend to initiate the study of stochastic process associated to evolution operators (Hamiltonians) exactly integrable and conformally invariant. (AU)
