Título: | New approach to large-scale nuclear structure calculations |
Autor: | Dukelsky, Jorge CSIC ORCID; Pittel, S. | Fecha de publicación: | 2-may-2001 | Editor: | American Physical Society | Citación: | Physical Review C - Nuclear Physics 63: 613031-613034 (2001) | Resumen: | A new approach to large-scale nuclear structure calculations, based on the density matrix renormalization group (DMRG), is described. The method is tested in the context of a problem involving many identical nucleons constrained to move in a single large-j shell and interacting via a pairing plus quadrupole interaction. In cases in which exact diagonalization of the Hamiltonian is possible, the method is able to reproduce the exact results for the ground-state energy and the energies of low-lying excited states with extreme precision. Results are also presented for a model problem in which exact solution is not feasible. ©2001 American Physical Society | Descripción: | 4 págs.; 1 fig.; 3 tabs. ; Rapid communications ; PACS number(s): 21.60.Cs, 05.10.Cc | Versión del editor: | https://doi.org/10.1103/PhysRevC.63.061303 | URI: | http://hdl.handle.net/10261/142711 | DOI: | 10.1103/PhysRevC.63.061303 | Identificadores: | doi: 10.1103/PhysRevC.63.061303 issn: 0556-2813 |
