Abstract
We formulate a method for incorporating quantum fluctuations into mole cular-dynamics simulations of many-body systems, such as those employe d for energetic nuclear collision processes. Based on Fermi's golden r ule, we allow spontaneous transitions to occur between the wave packet s which are not energy eigenstates. The ensuing diffusive evolution in the space of the wave packet parameters exhibits appealing physical p roperties, including relaxation towards quantum statistical equilibriu m.
