动力学非交换性

Dynamical noncommutativity

M. Gomes, V. G. Kupriyanov, A. J. da Silva

摘要:

提出了动态非交换性模型。该系统由两个相互关联的部分组成。其中第一个描述了坐标为q^1,q^2的物理自由度,第二个对应于具有适当动力学的非对易性r。量子化后,两个物理坐标的换位子与r的函数成正比。我们的模型的有趣的特点是非局域性的系统的能量的依赖。能量越大,非定域性越强。Lidding贡献是由于非对易性模,然而,物理自由度在θ中的高阶非定域性中也有贡献。

英文摘要:

The model of dynamical noncommutativity is proposed. The system consists of two interrelated parts. The first of them describes the physical degrees of freedom with coordinates q^1, q^2, the second one corresponds to the noncommutativity r which has a proper dynamics. After quantization the commutator of two physical coordinates is proportional to the function of r. The interesting feature of our model is the dependence of nonlocality on the energy of the system. The more the energy, the more the nonlocality. The lidding contribution is due to the mode of noncommutativity, however, the physical degrees of freedom also contribute in nonlocality in higher orders in θ.
