非对易坐标系中的偶极子动力学和量子相位

Dynamics of Dipoles and Quantum Phases in Noncommutative Coordinates

Omer F. Dayi

摘要:

在非对易坐标系中,研究了具有电、磁偶极矩的自旋为1/2的中性粒子与外电场、外磁场相互作用的动力学。空间的非对易性被插入到半经典约束哈密顿系统中。研究了粒子与电磁场相互作用所获得的量子相位与作用在系统上的(半)经典力之间的关系,并将其推广到非对易坐标系中建立量子相位的公式。一般形式主义是适用于物理系统产生的Aharonov-Bohm,Aharonov-Casher,他-McKellar-Wilkens和Anandan阶段在非交换坐标。的非交换性参数θ的界限推导出变形相的Aharonov-Bohm和Aharonov-Casher相的实验数据进行比较。

英文摘要:

The dynamics of a spin--1/2 neutral particle possessing electric and magnetic dipole moments interacting with external electric and magnetic fields in noncommutative coordinates is obtained. Noncommutativity of space is interposed in terms of a semiclassical constrained Hamiltonian system. The relation between the quantum phase acquired by a particle interacting with an electromagnetic field and the (semi)classical force acting on the system is examined and generalized to establish a formulation of the quantum phases in noncommutative coordinates. The general formalism is applied to physical systems yielding the Aharonov-Bohm, Aharonov-Casher, He-McKellar-Wilkens and Anandan phases in noncommutative coordinates. Bounds for the noncommutativity parameter theta are derived comparing the deformed phases with the experimental data on the Aharonov-Bohm and Aharonov-Casher phases.
