Microcanonical Thermodynamic Properties of Helium Nanodroplets
arXiv:physics/0304073 · doi:10.1063/1.1588991
Abstract
The density of states and other thermodynamic functions of helium nanodroplets are calculated for a microcanonical ensemble with both energy and total angular momentum treated as conserved quantum numbers. These functions allow angular momentum conserving evaporative cooling simulations. As part of this project, a recursion relationship is derived for the reduction to irreducible representations of the n'th symmetric power of the irreducible representations of the rotation group. These give the distribution of total angular momentum states generated by putting multiple quanta into a ripplon or phonon mode of the droplet, each of which is characterized by a angular momentum quantum number.
