Microscopic dynamics of small fragmenting systems

Abstract

We calculate the Caloric Curve of fragmenting drops of Lennard Jones particles, defined as the temperature of the system at fragmentation time. We show how to calculate the time of fragment formation, and the temperature at this time. We explore the role played by the collective motion. The competition between the collective radial, ordered, motion and the intrisic, chaotic, motion is analyzed using the Maximum Local Lyapunov Exponent.
