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-…
