概要

• 論文の詳細を見る

• With the aim of describing statistically mixed states in realistic many-body systems, the su(n)- and the su(n, 1)-algebra in the Schwinger boson representation are presented in a form generalized from the su(2)- and the su(1, 1)-algebra. The generators of the two algebras are expressed in terms of certain bilinear forms for boson operators. Some concrete examples are discussed in detail.
