- 論文の詳細を見る
Recently we reformulated the selfconsistent collective-coordinate (SCC) method of Marumori, Maskawa, Sakata and Kuriyama. In this reformulation, biunitary forms of state vectors are used and the resultant representation corresponds to a c-number image of the Dyson-type boson expansion theory. This non-unitary version of the SCC method is rederived from a general point of view in order to clarify the relation to the original unitary version. Moreover, it is shown that the expansion technique to solve the basic equations is as applicable to this new version as to the unitary one, so that applications to realistic problems are easily done.
