Abstract

Depending on the energy regime, the dynamics of heavy-ion collisions reveals a variety of different mechanisms which are attributed to the combination of collective and dissipative effects. Semi-classical approaches have been successful in describing chaotic regimes at Fermi-energies but they gradually lose precision when extending to collective behaviour and in general when low-energy features become more determinant in the dynamics. To improve on this description, we propose a theoretical approach starting from the TDHF scheme. A quantum representation with a moving basis function has been worked out with a double aim. Firstly, achieving a simplified solution to handle the evolution in time. Secondly, introducing beyond-mean-field extensions and stochastic contributions. Applications to nuclear collisions at incident energies around low to Fermi energy are presented.
