Extended Gibbs ensembles with flow

Mostrar todas las versiones(2)

A recently proposed statistical treatment of finite unbound systems in the presence of collective motions is applied to a classical Lennard-Jones system, numerically simulated through molecular dynamics. In the ideal gas limit, the flow dynamics can be exactly recast into effective time-dependent La...
