Quantum phases of correlated electrons in artificial molecules under magnetic fields
Devis Bellucci, Massimo Rontani, Guido Goldoni +1
We investigate the stability of few-electron quantum phases in vertically coupled quantum dots under a magnetic field of arbitrary strength and direction. The orbital and spin stab…
Full configuration interaction approach to the few-electron problem in artificial atoms
Massimo Rontani, Carlo Cavazzoni, Devis Bellucci +1
We present a new high-performance configuration interaction code optimally designed for the calculation of the lowest energy eigenstates of a few electrons in semiconductor quantum…
Collective properties of electrons and holes in coupled quantum dots
Guido Goldoni, Filippo Troiani, Massimo Rontani +3
We discuss the properties of few electrons and electron-hole pairs confined in coupled semiconductor quantum dots, with emphasis on correlation effects and the role of tunneling. W…
Competing mechanisms for singlet-triplet transition in artificial molecules
Devis Bellucci, Massimo Rontani, Filippo Troiani +2
We study the magnetic field induced singlet/triplet transition for two electrons in vertically coupled quantum dots by exact diagonalization of the Coulomb interaction. We identify…
Spin-Spin Interaction In Artificial Molecules With In-Plane Magnetic Field
Devis Bellucci, Massimo Rontani, Guido Goldoni +2
We investigate theoretically the spin-spin interaction of two-electrons in vertically coupled QDs as a function of the angle between magnetic field and growth axis. Our numerical a…
