The exact solution of the SU(2) pairing Hamiltonian with non-degenerate single particle orbits was introduced by Richardson in the early sixties. The exact solution passed almost unnoticed till was recovered in the last decade in an effort to describe the disappearance of superconductivity in ultra-small superconducting grains. Since then it has been extended to several families integrable models, called the RichardsonGaudin (RG) models. In particular, the rational family of integrable RG models has been widely applied to mesoscopic systems like small grains, quantum dots and nuclear systems where finite size effects play an important role. We will first introduce these families of integrable models and then we will describe the first applications of the hyperbolic family to spinless cold fermionic atoms in two dimensional lattices and to heavy nuclei. | Descripción: | 14 pags.; 5 figs.; PACS: 02.30.Ik,24.10.Cn. | Versión del editor: | http://www.nipne.ro/rjp/2015_60_5-6/0753_0766.pdf | URI: | http://hdl.handle.net/10261/128682 | ISSN: | 1221-146X |
