Configuration interaction approach to Fermi liquid-Wigner crystal mixed phases in semiconductor nanodumbbells
Planelles, Josep; Movilla, Jose L.; Ballester Caudet, Ana; Escartín, J. M.; Pi, Martí American Institute of Physics (AIP) (2012)Full configuration interaction calculations demonstrate the existence of mixed correlation phases in truly three-dimensional elongated nanocrystals subject to inhomogeneous spatial confining potentials. In such phases, the ... -
Dielectric confinement in quantum dots of arbitrary shape within the local spin density approximation: Diluted regimes in elongated quantum dots
Movilla, Jose L.; Pi, Martí; Planelles, Josep American Institute of Physics (2010)We propose a simplified and computationally feasible model accounting for the dielectric confinement in arbitrarily shaped many-electron quantum dots, within the local spin density approximation. The model yields quite ... -
From quantum dots to quantum wires: electronic structure of semiconductor nanorods
Planelles, Josep; Royo Valls, Miguel; Ballester Caudet, Ana; Pi, Martí American Physical Society (2009)The transition bridge between zero-dimensional quantum dots and one-dimensional quantum wires is explored theoretically by means of the construction of the addition energy spectra of nanorods with different lengths. Spin ... -
Isospin phases of vertically coupled double quantum rings under the influence
Planelles, Josep; Pi, Martí; Barranco, Manuel; Malet, Francesc; Royo Valls, Miguel American Physical Society (2008)Vertically coupled double quantum rings submitted to a perpendicular magnetic field B are addressed within the local spin-density-functional theory. We describe the structure of quantum ring molecules containing up to 40 ... -
Mixed correlation phases in elongated quantum dots
Ballester Caudet, Ana; Escartín, J. M.; Movilla, Jose L.; Pi, Martí; Planelles, Josep American Physical Society (2010-09-07)It is theoretically shown, within the local spin-density-functional theory framework, that inhomogeneous confining potentials in elongated, diluted N-electron quantum dots may lead to the formation of mixed phases in which ...
