Creffield, Charles E. ; Kornilovitch, P. E. ; Klepfish, E. G. ; Pike, E. R. ; Sarkar, Sarben | IOP Publishing Ltd. | 1997-05-05A Quantum Monte Carlo calculation of dynamical spin susceptibility in the half-filled 2D Hubbard model is presented for temperature T = 0.2t and an intermediate on-site repulsion U = 4t. Using the singular value decomposition technique we succee[...]texto impreso
Spectral weight function for the half-filled hubbard-model - a singular-value decomposition approach
Creffield, Charles E. ; Klepfish,, E.G. ; Pike, E. R. ; Sarkar, Sarben | American Physical Society | 1995-07-17The singular value decomposition technique is used to reconstruct the electronic spectral weight function for a half-filled Hubbard model with on-site repulsion U = 4t from quantum Monte Carlo data. A two-band structure for the single-particle e[...]texto impreso
