Abstract
Femtosecond measurement techniques have been applied previously to determine the damping rate of nonequilibrium acoustic phonon modes in a spherical quantum dot. In this account, the elastic continuum model of acoustic phonons is applied to model theoretically the damping rate of such nonequilibrium acoustic phonons. These calculations suggest that mechanical damping is a dominant mechanism for the previously observed damping.
