Exchange energy and stability diagram of few-electron coupled elongated quantum dots
L. -X. Zhang, D. V. Melnikov, J. -P. Leburton
We study the properties of a few-electron system confined in coupled elongated quantum dots (QDs) using a model Gaussian potential and the numerical exact diagonalization technique…
The von Neumann-Wigner theorem in quantum dot molecules
L. -X. Zhang, D. V. Melnikov, J. -P. Leburton
We show that electrons in coupled quantum dots characterized by high aspect ratios undergo abrupt density rotations when the dots are biased into an asymmetric confinement configur…
Size effects in the exchange coupling between two electrons in quantum wire quantum dots
L. -X. Zhang, D. V. Melnikov, S. Agarwal +1
We theoretically investigate the properties of a two-electron system confined in the three-dimensional potential of coupled quantum dots formed in a quantum wire. For this purpose,…
Exchange interaction and stability diagram of coupled quantum dots in magnetic fields
L. -X. Zhang, D. V. Melnikov, J. -P. Leburton
The charge stability diagram for two coupled quantum dots containing up to two electrons is computed in magnetic fields. One- and two-particle Schroedinger equations are solved by…
Single-electron charging and detection in a laterally-coupled quantum dot circuit in the few-electron regime
L. -X. Zhang, P. Matagne, J. P. Leburton +2
We provide a physical analysis of the charging and detection of the first few electrons in a laterally-coupled GaAs/AlGaAs quantum dot (LCQD) circuit with integrated quantum point…
Few-Electron Quantum Dot Circuit with Integrated Charge Read-Out
J. M. Elzerman, R. Hanson, J. S. Greidanus +5
We report on the realization of a few-electron double quantum dot defined in a two-dimensional electron gas by means of surface gates on top of a GaAs/AlGaAs heterostructure. Two q…
