We investigate the dynamics of two interacting electrons confined to a pair of coupled quantum dots driven by an external ac field. By numerically integrating the two-electron Schrodinger equation in time, we find that for certain values of the strength and frequency of the ac field the electrons can become localized within just one of the dots, in spite of the Coulomb repulsion. Reducing the system to an effective two-site model of Hubbard type, and applying Floquet theory, leads to a detailed…

Two-electron localization in a quantum dot molecule driven by bichromatic electric fields
We investigate the dynamics of two interacting electrons confined in a symmetric double quantum dot structure under the influence of bichromatic electric fields. The theoretical analysis is based on
Control of electron localization in a coupled quantum dot structure
Abstract We systematically investigate the dynamical behaviour of an electron in a double quantum dot system under the influence of an external AC field. It is assumed that the quantum dot confined
Dynamical control of correlated states in a square quantum dot
In the limit of low particle density, electrons confined to a quantum dot form strongly correlated states termed Wigner molecules, in which the Coulomb interaction causes the electrons to become
Effect of Coulomb Interaction on Dynamical Localization in a Two-Electron Quantum-Dot Molecule
The combined interaction of Coulomb interaction and ac fields with two electrons in a quantum dot molecule is studied respectively with numerical simulation, perturbation theory and the approximation
Dynamical Localization in a Two-Electron Quantum Dot Molecule Biased by a dc Voltage
We study the dynamics of two interacting electrons in a coupled-quantum-dot system with a time-dependent external electric field. The numerical results of the two-particle states reveal that the
