非对易量子力学幺正不可约表示规范等价类的Wigner函数

Wigner functions for gauge equivalence classes of unitary irreducible representations of noncommutative quantum mechanics

S. Hasibul Hassan Chowdhury, Hishamuddin Zainuddin

摘要:

虽然形成量子态的相空间表示的维格纳函数是众所周知的事实,但它们在非对易量子力学(NCQM)中的构造仍然相对较少为人所知,特别是在规范依赖性方面。本文讨论了用李群$\g$的幺正不可约表示(UIR)的规范等价类的2参数族构造2自由度系统的NCQM的Wigner函数,该李群已被确定为NCQM的运动对称群。这种一般构造的维格纳函数的NCQM,反过来,产生特殊情况下的朗道和对称规范的NCQM。

英文摘要:

While Wigner functions forming phase space representation of quantum states is a well-known fact, their construction for noncommutative quantum mechanics (NCQM) remains relatively lesser known, in particular with respect to gauge dependencies. This paper deals with the construction of Wigner functions of NCQM for a system of 2-degrees of freedom using 2-parameter families of gauge equivalence classes of unitary irreducible representations (UIRs) of the Lie group $\g$ which has been identified as the kinematical symmetry group of NCQM in an earlier paper. This general construction of Wigner functions for NCQM, in turn, yields the special cases of Landau and symmetric gauges of NCQM.
