Electron dynamics in AC-driven quantum dots

A quantum dot (QD) is a structure in which electrons can be confined to small length scales, comparable to their Fermi wavelength. A set of electrons held in such a structure is conceptually similar to a set of atomic electrons bound to a nucleus, and for this reason quantum dots are sometimes termed “artificial atoms” [1]. Unlike real atoms, the physical properties of quantum dots can be easily varied, which gives theorists and experimentalists the opportunity to study novel quantum effects in a well-controlled system.
