    "abstract": "An exact stochastic model for the thermalisation of quantum states is\nproposed. The model has various physically appealing properties. The dynamics\nare characterised by an underlying Schrodinger evolution, together with a\nnonlinear term driving the system towards an asymptotic equilibrium state and a\nstochastic term reflecting fluctuations. There are two free parameters, one of\nwhich can be identified with the heat bath temperature, while the other\ndetermines the characteristic time scale for thermalisation. Exact expressions\nare derived for the evolutionary dynamics of the system energy, the system\nentropy, and the associated density operator.",
