One-particle irreducible density matrix for the spin disordered infinite $U$ Hubbard chain | Vadim V. Cheianov

12 Nov 2003 | Subject: | Strongly Correlated Electrons | cond-mat.str-el | Abstract: | In this Letter we present a calculation of the one-particle irreducible density matrix $
ho(x)$ for the one-dimensional (1D) Hubbard model in the infinite $U$ limit. We consider the zero temperature spin disordered regime, which is obtained by first taking the limit $U o infty$ and then the limit $T o 0.$ Using the determinant representation for $
ho(x)$ we derive analytical expressions for both large and small $x$ at an arbitrary filling factor $0 | Source: | arXiv, cond-mat/0311256 | Services: | Forum | Review | PDF | Favorites |
