摘要
We show that any fixed number of fermions (Jastrow projected or not) BCS wave functions can be represented as determinants. This is important for their numerical investigation, with applications to liquid He3 and Hubbard's model. We also propose a new type of wave function, describing a 'mixed' state composed of paired and unpaired fermions. The physical properties of such a state are tentatively discussed.
