Orbital current mode in elliptical quantum dots
arXiv:cond-mat/9909135 · doi:10.1103/PhysRevB.60.R13966
Abstract
An orbital current mode peculiar to deformed quantum dots is theoretically investigated; first by using a simple model that allows to interpret analytically its main characteristics, and second, by numerically solving the microscopic equations of time evolution after an initial perturbation within the time-dependent local-spin-density approximation. Results for different deformations and sizes are shown.
