三维二次代数的实现与表示

Three dimensional quadratic algebras: Some realizations and representations

V. Sunil Kumar, B. A. Bambah, R. Jagannathan

摘要:

利用$su(2)$和$su(1,1)$的双模玻色实现的推广,构造了四类$\lsb Q_0 , Q_\pm \rsb$ $=$ $\pm Q_\pm$,$\lsb Q_+ , Q_- \rsb$ $=$ $aQ_0^2 + bQ_0 + c$型三维二次代数,其中$(a,b,c)$是代数的常数或中心元.由此得到的矩阵表示和单变量微分算子实现。给出了这些代数的数学和物理相关性的一些评论。

英文摘要:

Four classes of three dimensional quadratic algebras of the type $\lsb Q_0 , Q_\pm \rsb$ $=$ $\pm Q_\pm$, $\lsb Q_+ , Q_- \rsb$ $=$ $aQ_0^2 + bQ_0 + c$, where $(a,b,c)$ are constants or central elements of the algebra, are constructed using a generalization of the well known two-mode bosonic realizations of $su(2)$ and $su(1,1)$. The resulting matrix representations and single variable differential operator realizations are obtained. Some remarks on the mathematical and physical relevance of such algebras are given.
