Abstract
An orbital current mode peculiar to deformed quantum dots is theoretically investigated; first by using a simple model that makes it possible to analy tically interpret its main characteristics, and second, by numerically solv ing the microscopic equations of time evolution after an initial perturbati on within the time-dependent local-spin-density approximation. Results for different deformations and sizes are shown. [S0163-1829(99)50244-0].
