Overlaps and matrix elements of physical operators between
arbitrary HFB states.
Beyond mean field methods have been widely used in various
many-body quantum systems. However, there still are some
problems to be solved in the implementation of beyond mean
field calculations. Especially for systems with large number
of particles, such as heavy nuclei, the efficiency of beyond
mean
field calculations becomes a very serious problem. Recently,
we have tried to figure out a convenient way of calculating
the overlap between arbitrary HFB vacua [1]. We also found
some compact formulae for the matrix elements of physical
operators (e.g. Hamiltonian) between arbitrary HFB
multiquasiparticle states [2]. These formulae may reduce the
computational time by several orders of magnitude when
applied to many-body quantum system in a large Fock space.
