    "abstract": "Global equilibrium fragmentation inside a freeze out constraining volume is a\nworking hypothesis widely used in nuclear fragmentation statistical models. In\nthe framework of classical Lennard Jones molecular dynamics, we study how the\nrelaxation of the fixed volume constraint affects the posterior evolution of\nmicroscopic correlations, and how a non-confined fragmentation scenario is\nestablished. A study of the dynamical evolution of the relative kinetic energy\nfluctuations was also performed. We found that asymptotic measurements of such\nobservable can be related to the number of decaying channels available to the\nsystem at fragmentation time.",
