作为约束系统的非对易量子力学的正则结构

Canonical Structure of Noncommutative Quantum Mechanics as Constraint System

M. Nakamura

摘要:

从一阶奇异拉格朗日量出发,研究了坐标和动量均为非对易的非对易量子力学的正则结构。利用约束系统和约束星积的投影算符方法(POM),构造了非对易量子系统,并导出了该系统的{ \it投影}正则共轭集(CCS)的换位子代数,其形式包含了非对易参数的所有阶.讨论了服从普通非交换换位子代数的替代CCS。在POM的框架下构造了{ \it exact} CCS,并证明了它等价于通过Seiberg-Witten映射和Bopp位移构造的CCS.我们进一步讨论了另一种拉格朗日量来实现坐标和动量的不可对易性。

英文摘要:

Starting with the first-order singular Lagrangian, the canonical structure in the noncommutative quantum mechanics with the noncommutativities both of coordinates and momenta is investgated. Using the projection operator method (POM) for the constraint systems and the constraint star-product, the noncommutative quantum system is constructed and the commutator algebra of {\it projected} canonically conjugate set(CCS) of the system is derived in the form including all orders of the noncommutativity parameters. We discuss the alternative CCS, which obeys the ordinary noncommutative commutator algebra. The {\it exact} CCS is constructed in the framework of the POM, and which is shown to be equivalent to the CCS constructed through the Seiberg-Witten map and the Bopp shift. We further discess the alternative Lagrangian to realize the noncommutativities both of coordinates and momenta.
