Many-body Dyson equation approach to the seniority model of pairing
arXiv:2004.01763 · doi:10.1142/S0218301320500238
Abstract
As is well known, the single level seniority model of pairing has been solved exactly since long using angular momentum algebra. It is shown that it can also be solved using the Dyson equation of standard many-body theory. The formalism shows some interesting many-body aspects.
