Renormalization of the Hartree-Fock-Bogoliubov equations in the case of a zero range pairing interaction

Renormalization of the Hartree-Fock-Bogoliubov equations in the case of a zero range pairing interaction

We introduce a natural and simple way to implement the regularization scheme of the Hartree-Fock-Bogoliubov equations with zero range pairing interaction. The renormalization scheme proves to be equivalent to a simple energy cutoff with a position dependent running coupling constant.
