- W1966383237 abstract "A unified algebraic approach to both the hard-core Fermi– and Bose–Hubbard models is extended to both the finite- and infinite-site with periodic condition cases. Excitation energies and the corresponding wavefunctions of both the models with nearest neighbor hopping are exactly derived by using a new and simple algebraic method. It is found that spectra of both the models are determined simply by eigenvalue problem of N × N hopping matrix, where N is the number of sites for finite system or the period of sites for infinite system." @default.
