变形代数的相干态

Coherent States for the Deformed Algebras

V. Sunilkumar, B. A. Bambah, P. K. Panigrahi, V. Srinivasan

摘要:

我们提供了一个统一的方法来寻找各种变形代数,包括二次,希格斯和q-变形代数,这是相关的许多物理问题的相干态。对于非紧的情况,相干态,这是各自的湮灭运营商的本征态,构造通过寻找这些运营商的正则共轭。我们给出了将这些变形代数映射到适当的李代数的一般过程。广义相干态,在Perelomov意义上,遵循这个结构。

英文摘要:

We provide a unified approach for finding the coherent states of various deformed algebras, including quadratic, Higgs and q-deformed algebras, which are relevant for many physical problems. For the non-compact cases, coherent states, which are the eigenstates of the respective annihilation operators, are constructed by finding the canonical conjugates of these operators. We give a general procedure to map these deformed algebras to appropriate Lie algebras. Generalized coherent states, in the Perelomov sense, follow from this construction.
