    • openAccess   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 ...

    • openAccess   Coupled donors in quantum dots: quantum size and dielectric mismatch effects 

      Movilla, Jose L.; Ballester Caudet, Ana; Planelles, Josep American Physical Society (2009)
      Spatial and dielectric confinement modulations of the spontaneous emission rates, transition energies, and charge-density distributions of a singly ionized double donor system (D2+) in a spherical quantum dot are calculated ...

    • openAccess   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 ...

    • openAccess   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 ...

    • openAccess   Multi-particle states of semiconductor hexagonal rings: Artificial benzene 

      Planelles, Josep; Ballester Caudet, Ana; Bertoni, Andrea American Institute of Physics (AIP) (2012)
      We present a theoretical and numerical investigation of correlated multi-electron states of hexagonal semiconductor rings. Both single-particle and correlated states show localization patterns in the six corners and ...

    • closedAccess   One- and Two-Photon Absorption in CdS Nanodots and Wires: The Role of Dimensionality in the One- and Two-Photon Luminescence Excitation Spectrum 

      Achtstein, Alexander W.; Ballester Caudet, Ana; Movilla, Jose L.; Hennig, Jonas; Climente, Juan I.; Prudnikau, Anatol V.; Antanovich, Artsiom; Scott, Riccardo; Artemyev, Mikhail V.; Planelles, Josep; Woggon, Ulrike American Chemical Society (2014-12)
      We investigate the spectral dependence of the linear and two-photon absorption of wurtzite CdS nanoparticles (dots and rods) by means of quantitative one- and two-photon photoluminescence excitation spectroscopy and effective ...

    • openAccess   Two-Photon Induced Blue Shift of Core and Shell Optical Transitions in Colloidal CdSe/CdS quasi-type II Quantum Rods 

      Allione, Marco; Ballester Caudet, Ana; Li, Hongbo; Comin, Alberto; Movilla, Jose L.; Climente, Juan I.; Manna, Liberato; Moreels, Iwan American Chemical Society (2013-03)
      The spectral dependence of the two-photon absorption in CdSe/CdS core/shell nanocrystal heterorods has been studied via two-photon-induced luminescence excitation spectroscopy. We verified that the two-photon absorption ...
