Abstract:
In the present paper we give the explicit expressions for the ground state of a many boson system in different mean field approximations, such as Hartree-Bose, Bogoliubov, the particle-hole random phase approximation (RPA), and its coupling with the particle-particle (RPA). The ground states obtained satisfy the requirement that the annihilation operators of the elementary excitations annihilates them. In all cases the ground state wave functions can be understood as a condensate of pairs of bosons. © 1994 The American Physical Society.
