✦ Synopsis

In conventional theories, the origin of the pairing force and the formation of the superfiuid state are treated separately. In real nuclei, however, the nucleon responsible for the attractive interaction is identical with the nucleon that stabilizes the superfluid state. Hence, the superfluid state modifies the attractive force, and this attractive force determines the superfluid state, leading to a feedback effect. In this paper, as a preliminary attempt, we incorporate the effective interaction and formation of the superfluid state into a common self-consistency scheme. Furthermore, the alpha-correlation is included into this scheme as well. Applying the Ginzburg-Landau formalism to this scheme, a dynamics of the nucleon pairing and alpha-correlation is studied.
