Pairing of Parafermions of Order 2: Seniority Model | Charles A. Nelson
; | Date: |
7 Aug 2003 | Journal: | J.Phys. A37 (2004) 2497-2508 | Subject: | hep-ph hep-th nucl-th | Abstract: | As generalizations of the fermion seniority model, four multi-mode Hamiltonians are considered to investigate some of the consequences of the pairing of parafermions of order two. 2-particle and 4-particle states are explicitly constructed for H_A = - G A^+ A with A^+}= 1/2 Sum c_{m}^+ c_{-m}^+ and the distinct H_C = - G C^+ C with C^+}= 1/2 Sum c_{-m}^+ c_{m}^+, and for the time-reversal invariant H_(-)= -G (A^+ - C^+)(A-C) and H_(+) = -G (A^+dagger + C^+)(A+C), which has no analogue in the fermion case. The spectra and degeneracies are compared with those of the usual fermion seniority model. | Source: | arXiv, hep-ph/0308090 | Services: | Forum | Review | PDF | Favorites |
