A 31 (1998) 7729 | | Subject: | Condensed Matter; Exactly Solvable and Integrable Systems | cond-mat hep-th nlin.SI solv-int | | Abstract: | We develop a general scheme for the use of Fermi operators within the framework of integrable systems. This enables us to read off a fermionic Hamiltonian from a given solution of the Yang-Baxter equation and to express the corresponding $L$-matrix and the generators of symmetries in terms of Fermi operators. We illustrate our approach through a number of examples. Our main example is the algebraic Bethe ansatz solution of the Hubbard model in the infinite coupling limit. | | Source: | arXiv, cond-mat/9805129 | | Services: | Forum | Review | PDF | Favorites | |
