一般非对易空间上耦合谐振子的形变量子化

Deformation quantization for coupled harmonic oscillators on a general noncommutative space

Bing-Sheng Lin, Si-Cong Jing, Tai-Hua Heng

摘要:

形变量子化是研究某些经典系统的有力工具,特别是在非对易空间中。在这项工作中,我们首先表明,对于一类特殊的汉密尔顿,人们可以很容易地找到相关的时间演化函数和维格纳函数,它们是变形量子化理论中固有的重要量。在此基础上,我们研究了一般非对易相空间上的两个耦合谐振子系统,要求空间坐标和动量坐标不对易。我们导出了该系统的所有Wigner函数和相应的能谱,并考虑了几种有趣的特殊情况,得到了一些有意义的结果。

英文摘要:

Deformation quantization is a powerful tool to quantize some classical systems especially in noncommutative space. In this work we first show that for a class of special Hamiltonian one can easily find relevant time evolution functions and Wigner functions, which are intrinsic important quantities in the deformation quantization theory. Then based on this observation we investigate a two coupled harmonic oscillators system on the general noncommutative phase space by requiring both spatial and momentum coordinates do not commute each other. We derive all the Wigner functions and the corresponding energy spectra for this system, and consider several interesting special cases, which lead to some significant results.
