Enhancement of kinetic energy fluctuations due to expansion

Global equilibrium fragmentation inside a freeze-out constraining volume is a working hypothesis widely used in nuclear fragmentation statistical models. In the framework of classical Lennard-Jones molecular dynamics, we study how the relaxation of the fixed volume constraint affects the posterior e...
