1307.6905 (Qing-Li Hu et al.)

Matrix elements of one-body and two-body operators between arbitrary HFB
multi-quasiparticle states

Qing-Li Hu, Zao-Chun Gao, Y. S. Chen
We present new formulae for the matrix elements of one-body and two-body physical operators in compact forms, which are applicable to arbitrary Hartree-Fock-Bogoliubov wave functions, including those for multi-quasiparticle excitations. The test calculations show that our formulae may substantially accelerate the process of symmetry restoration when applied to the heavy nuclear system.
