Abstract

An ab initio analysis of laser driven, few-electron plasmon dynamics in a finite lateral quantum dot is performed. The results are analyzed by a comparison to a Drude model based on the center-of-mass motion of the plasmon. We find that decay and energy absorption during the plasmon-surface interaction do not depend on electron correlation. This suggests that the Kohn theorem---plasmon dynamics in infinite parabolic quantum dots does not depend on electron correlation---is extendable to finite quantum dots.
