FI: RECENT DEVELOPMENTS OF AMD FOR HEAVY-ION COLLISIONS: DISENTANGLING COMPONENTS OUT OF A WAVE PACKET
SEZIONE DI FIRENZE
Seminario prof. Akira Ono Abstract: The antisymmetrized molecular dynamics (AMD) approach tries to describe heavy-ion collision dynamics, such as multifragmentation, by approximately solving the time evolution of a Slater determinant of Gaussian wave packets. A wave packet in general can be decomposed into many components. In the AMD approach, it is essential to disentangle components randomly in solving the time evolution so that many reaction channels will appear with suitable probabilities. Putting emphasis on this viewpoint, I will discuss recent developments of the AMD code. In multifragmentation, we find important roles played by cluster correlations. The treatment of the wave-packet momentum width has been improved for a better description of energy spectra of emitted particles. We also developed a method to generate test particles out of the AMD wave function, which is used to more precisely treat two-nucleon collisions and to combine AMD with another transport code.
