Mean field description of the ground state of many boson systems relevant to nuclei

Mostrar todas las versiones(2)

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 obtaine...
