Abstract
We compare several methods for incorporating the effect of the fluctuating collision integral in Boltzmann-Uehling-Uhlenbeck simulations of nuclear dynamics: the method of correlated pseudo-particle collisions proposed by Bauer, Bertsch, and Das Gupta, the method of projection onto collective variables (specifically the local quadrupole moment of the momentum distribution) proposed by Ayik and Gregoire, and the method of direct simulation on a lattice in phase space recently proposed by Burgio, Chomaz, and Randrup. Considering a periodic two-dimensional nucleon gas in a constant one-body field, we examine the evolution of the fluctuations of the phase-space occupancy and their correlations. (orig.).
