Independent Descriptions of the Collective Degrees of Freedom of Nuclei (II)

Abstract

The operatorized Bogoliubov transformation introduced in the previous paper is generalized so that it can be used in microscopic descriptions of the collective degrees of freedom independent of both the monopole and quadrupole degrees of freedom.

Independent Descriptions of the collective Degrees of Freedom of Nuclei (I)

Lu DaHai, Yang LiMing

The present paper attempts to give independent descriptions of the collective degrees of freedom of nuclei such as the monopole and quadrupole ones in order to avoid the seniority mixing problem. This is done by the operatorized Bogoliubov transformation (OBT) which separates the degree of freedom from the rest described by the seniority particle operator which is not coupling to the pairs, and in terms of which the independent pair is composed. The OBT is derived in such a way that it can be generalized easily to include a new kind of “seniority particle operator” neither coupling to the nor to the pairs. In terms of this new particle operator the independent pair or the independent odd particle in odd nuclei is constructed.

Quantized Bogoliubov Transformationand the Holon-Spinon Operator Formalism

T. Suzuki

It is shown that the method proposed by Nakajima to describe the spinon and holon degrees of freedom in strongly correlated electron systems is obtained as a special case of the quantized Bogoliubov transformation developed for a description of the nuclear pairing field.
