Impact of fragment formation on shear viscosity in the nuclear liquid-gas phase transition region

The dimensionless ratio of shear viscosity to entropy density $\ensuremath{\eta}/s$ typically has a minimum at phase transition as observed in many atomic and molecular systems. This quantity been under intense study high-energy heavy-ion collisions sign QCD or rapid crossover between hadronic quark-gluon degrees freedom. authors perform numerical simulations matter lower temperature associated with which may shed light on the nuclear liquid-gas its connection transition.
