Fluctuation in nuclear dynamics. A comparison of different methods

Abstract

A comparison of various methods recently proposed to incorporate fluctuations of the one-body density in the Boltzmann-Uehling-Uhlenbeck simulations of nuclear dynamics is presented. The evolution toward equilibrium of a periodic two-dimensional nucleon gas in a constant mean field is studied. The discussion is focused on the fluctuations and correlations of the momentum space occupancy predicted by three different methods: correlated pseudo-particle collisions proposed by Bauer, Bertsch, and Das Gupta; projection onto collective variables (specifically the local quadrupole moment of the momentum distribution) proposed by Ayik and Gregoire; and direct simulation on a lattice in phase space recently proposed by Burgio, Chomaz, and Randrup.
