  "abstract": "The 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.",
