Abstract

The two topics discussed here are the treatment of neutron-proton pairing and the problem of phase transitions in systems of neutrons and protons. The conclusions are based on exact calculations, possible in simplified situations, and the exact results are compared with the BCS treatment. QRPA, and many of its modifications, which are the most popular approaches to double beta decay, involve the quasiparticle transformation as a decisive first step. It is therefore imperative to understand its strengths and limitations.
