1 Mar 2000 | | Journal: | J.Phys. A33 (2000) 7305-7336 | | Subject: | Exactly Solvable and Integrable Systems | nlin.SI hep-th | | Affiliation: | Depto. de Fisica Teorica II, Universidad Complutense, Madrid, SPAIN | | Abstract: | We develop a systematic procedure for constructing quantum many-body problems whose spectrum can be partially or totally computed by purely algebraic means. The exactly-solvable models include rational and hyperbolic potentials related to root systems, in some cases with an additional external field. The quasi-exactly solvable models can be considered as deformations of the previous ones which share their algebraic character. | | Source: | arXiv, nlin.SI/0003005 | | Services: | Forum | Review | PDF | Favorites | |
