Intense terahertz laser fields on a quantum dot with Rashba spin-orbit coupling
Abstract
We investigate the effects of the intense terahertz laser field and the spin-orbit coupling on single spin in a quantum dot. The laser field and the spin-orbit coupling can strongly affect the electron density of states and can excite a magnetic moment. The direction of the magnetic moment depends on the symmetries of the system, and its amplitude can be tuned by the strength and frequency of the laser field as well as the spin-orbit coupling.
