弯曲空间上的非对易量子力学

Noncommutative Quantum Mechanics on a Curved Space

M. Nakamura

摘要:

从一阶奇异拉格朗日量出发,利用投影算子方法(POM)和Dirac括号方法,研究了在导数型约束下高维欧氏空间子流形上非对易量子系统的正则结构.利用连续投影方法和Dirac括号的迭代性,构造了包含所有阶非对易参数的非对易量子系统.当非对易量子系统被约束在弯曲空间中时,给出了系统的换位子代数关于Dirac常数和非对易参数的一阶近似.

英文摘要:

Starting with the first-order singular Lagrangian, the canonical structures of the noncommutative quantum system on a submanifold embedded in the higher-dimensional Euclidean space are investigated with the projection operator method (POM) and the Dirac-bracket formulation in the case of the derivative-type constraint. Using the successive projection procedure and the iterativity of the Dirac bracket, the noncommutative quantum system is constructed in the form including all orders of the noncommutativity-parameters. When the noncommutative quantum system is constrained to a curved space, the commutator algebra of the system is presented within the 1st-order approximation with respect to Dirac-const. and the noncommutativity-parameters.
