Description
We show that due to the energy cutoff in the Hartree-Fock-Bogolyubov quasiparticle space, the Bogolyubov transformation becomes non-unitary. We propose a method of restoring the unitarity by introducing a truncated single-particle Hilbert space, in which the HFB equations are to be solved. (orig.)
