AbstractThe ratio of the shear viscosity (eta) to entropy density (s) for the intermediate energy heavy-ion collisions has been calculated by using the Green-Kubo method in the framework of the quantum molecular dynamics model. The theoretical curve of eta/s as a function of the incident energy for the head-on Au + Au collisions displays that a minimum region of eta/s has been approached at higher incident energies, where the minimum eta/s value is about 7 times Kovtun-Son-Starinets (KSS) bound (1/4 pi). We argue that the onset of minimum eta/s region at higher incident energies corresponds to the nuclear liquid gas phase transition in nuclear multifragmentation. Copyright (C) EPLA, 2012
