Fecha de publicación: | 17-jul-2007 | Editor: | American Physical Society | Citación: | Physical Review Letters 99(3): 032501 (2007) | Resumen: | The exact solution of the proton-neutron isoscalar-isovector (T=0,1) pairing Hamiltonian with nondegenerate single-particle orbits and equal pairing strengths is presented for the first time. The Hamiltonian is a particular case of a family of integrable SO(8) Richardson-Gaudin models. The exact solution of the T=0,1 pairing Hamiltonian is reduced to a problem of 4 sets of coupled nonlinear equations that determine the spectral parameters of the complete set of eigenstates. The microscopic structure of individual eigenstates is analyzed in terms of evolution of the spectral parameters in the complex plane for a system of A=80 nucleons. The spectroscopic trends of the exact solutions are discussed in terms of generalized rotations in isospace. | Descripción: | 4 pages, 2 figures.-- PACS nrs.: 21.60.Fw; 02.30.Ik; 74.20.Rp. | Versión del editor: | http://dx.doi.org/10.1103/PhysRevLett.99.032501 | URI: | http://hdl.handle.net/10261/15393 | DOI: | 10.1103/PhysRevLett.99.032501 | ISSN: | 0031-9007 | E-ISSN: | 1079-7114 |
