On the exactly solvable pairing models for bosons | | An.A.Ovchinnikov
; | | Date: |
17 May 2004 | | Journal: | JSTAT 0407 (2004) P004 | | Subject: | Mathematical Physics; Exactly Solvable and Integrable Systems | math-ph hep-th math.MP nlin.SI | | Abstract: | We propose the new exactly solvable model for bosons corresponding to the attractive pairing interaction. Using the electrostatic analogy, the solution of this model in thermodynamic limit is found. The transition from the superfluid phase with the Bose condensate and the Bogoliubov - type spectrum of excitations in the weak coupling regime to the incompressible phase with the gap in the excitation spectrum in the strong coupling regime is observed. | | Source: | arXiv, math-ph/0405047 | | Services: | Forum | Review | PDF | Favorites | |
