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,…
Many-body excitations in tunneling current spectra of a few-electron quantum dot
D. V. Melnikov, T. Fujisawa, D. G. Austing +2
Inherent asymmetry in the tunneling barriers of few-electron quantum dots induces intrinsically different tunneling currents for forward and reverse source-drain biases in the non-…
Engineering Exchange Coupling in Double Elliptic Quantum Dots
L. -X. Zhang, D. V. Melnikov, J. -P. Leburton
Coupled elliptic quantum dots with different aspect ratios containing up to two electrons are studied using a model confinement potential in the presence of magnetic fields. Single…
Spin configurations in circular and rectangular vertical quantum dots in a magnetic field: Three-dimensional self-consistent simulation
Dmitriy V. Melnikov, Philippe Matagne, Jean-Pierre Leburton +5
The magnetic field dependence of the electronic properties of \textit{real} single vertical quantum dots in circular and rectangular mesas is investigated within a full three-dimen…
