Variational approach to the Hubbard model in a C60 cluster

AuthorsGonzález Carmona, José ; Alvarez, J. V.
Issue Date1-May-1996
PublisherAmerican Physical Society
CitationPhysical Review B 53: 11729-11733 (1996)
AbstractWe propose a computational scheme for the Hubbard model in the C60 cluster in which the interaction with the Fermi sea of charges added to the neutral molecule is switched on sequentially. This is applied to the calculation of the balance of charging energies, within a low-energy truncation of the space of states which produces moderate errors for an intermediate range of the interaction strength. ©1996 American Physical Society
