Dynamics and thermodynamics of fragment emission from excited sources
In this paper we study the process of fragmentation of highly excited Lennard-Jones drops by studying the emission of stable fragments (clusters recognizable in configuration space that live more than a minimum lifetime). We focus on the dynamics and thermodynamics of the emitting sources and show,...
