Structure of the number projected BCS wave function

J. Dukelsky, S. Pittel, C. Esebbag

We study the structure of the number projected BCS (PBCS) wave function in the particle-hole basis, displaying its similarities with coupled clusters theory (CCT). The analysis of…

Solving the Richardson equations close to the critical points

F. Dominguez, C. Esebbag, J. Dukelsky

We study the Richardson equations close to the critical values of the paring strength g_c where the occurrence of divergencies preclude numerical solutions. We derive a set of equa…
