量子Heisenberg代数的相干态和压缩态

Coherent and squeezed states of quantum Heisenberg algebras

Nibaldo Alvarez-Moraga

摘要:

从变形量子海森堡李代数出发,给出了标准谐振子的一般产生算符和湮灭算符的实现。然后计算了相应的代数本征态,得到了新的变形相干态和压缩态。它们被变形的代数参数和适当的重新定义为paragrassmann数。分析了这些形变态的一些性质。

英文摘要:

Starting from deformed quantum Heisenberg Lie algebras some realizations are given in terms of the usual creation and annihilation operators of the standard harmonic oscillator. Then the associated algebra eigenstates are computed and give rise to new classes of deformed coherent and squeezed states. They are parametrized by deformed algebra parameters and suitable redefinitions of them as paragrassmann numbers. Some properties of these deformed states also are analyzed.
