In other words, the stochastic branching process in molecular dynamics is formulated so that the instantaneous time evolution of the averaged one-body distribution is essentially equivalent to the solution of Vlasov equation. Furthermore, as usual molecular dynamics, AMD-V keeps the many-body correlation and can naturally describe the fluctuation among many channels of the reaction. It is demonstrated that the newly introduced process of AMD-V has drastic effects in heavy ion collisions of 40Ca + 40Ca at 35 MeV/nucleon, especially on the fragmentation mechanism, and AMD-V reproduces the fragmentation data very well. Discussions are given on the interrelation among the frameworks of AMD, AMD-V and other microscopic models developed for the nuclear dynamics.", "revisions": [ { "version": "v1", "updated": "1996-01-09T09:54:41.000Z" } ], "analyses": { "keywords": [ "antisymmetrized molecular dynamics", "vlasov equation", "wave packets", "stochastic incorporation", "one-body distribution" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
