AMD approach to go beyond the mean field

Abstract

The single-particle motions of nucleons and the cluster correlations are both essential in understanding dynamics of heavy-ion collisions in a wide range of incident energies from several ten to several hundred MeV/nucleon. The antisymmetrized molecular dynamics approach has been improved in two directions, by introducing wave packet splitting in the first way, and by taking into account cluster correlations explicitly in the second way. I will review the basic ideas for these extensions which are closely related to the important physics in heavy-ion collisions. Some representative results are also reviewed such as for multifragmentation reactions and for virtually equilibrated systems in a box.
