Bifurcations in Boltzmann-Langevin One Body dynamics for fermionic systems

Abstract

We investigate the occurrence of bifurcations in the dynamical trajectories depicting nuclear collisions at Fermi energies. The quantitative description of the reaction dynamics is obtained within a novel one-body transport approach, based on the solution of the Boltzmann-Langevin equation in three dimensions, with a broad applicability for dissipative fermionic dynamics. Dilute systems formed in central collisions are shown to fluctuate between two energetically favourable mechanisms: reverting to a compact shape or rather disintegrating into several fragments. The latter result can be connected to the recent observation of bimodal distributions for quantities characterising fragmentation processes.
