Título: | Continuous unitary transformations in two-level boson systems |
Autor: | Dusuel, S.; Vidal, Julien; Arias, José María; Dukelsky, Jorge CSIC ORCID; García-Ramos, J.E. | Fecha de publicación: | 30-dic-2005 | Editor: | American Physical Society | Citación: | Physical Review C - Nuclear Physics 72: 064332 (2005) | Resumen: | Two-level boson systems displaying a quantum phase transition from a spherical (symmetric) to a deformed (broken) phase are studied. A formalism to diagonalize Hamiltonians with O(2L+1) symmetry for large number of bosons is worked out. Analytical results beyond the simple mean-field treatment are deduced by using the continuous unitary transformations technique. In this scheme, a 1/N expansion for different observables is proposed and allows one to compute the finite-size scaling exponents at the critical point. Analytical and numerical results are compared and reveal the power of the present approach to compute the finite-size corrections in such a context. © 2005 The American Physical Society. | Descripción: | 17 págs.; 16 figs.; 1 tab.; 3 apéndices ; PACS number(s): 21.60.Fw, 21.10.Re, 05.10.Cc, 75.40.Cx | Versión del editor: | http://dx.doi.org/10.1103/PhysRevC.72.064332 | URI: | http://hdl.handle.net/10261/141078 | DOI: | 10.1103/PhysRevC.72.064332 | Identificadores: | doi: 10.1103/PhysRevC.72.064332 issn: 0556-2813 |
