非线性西格玛模型的群量子化:S^2上的粒子

Group-quantization of non-linear sigma models: particle on S^2 revisited

V. Aldaya, M. Calixto, J. Guerrero, F. F. López-Ruiz

摘要:

我们提出了“部分迹”非线性西格玛模型的量子力学的理由,一个完全基于量子力学的程序。在概述了一般方案之后,明确地发展了双球上的粒子的特殊例子。作为一个显着的特点,没有显式的约束处理是必需的,也没有出现排序模糊。此外,能量谱恢复没有额外的条款,在球的曲率。

英文摘要:

We present the quantum mechanics of "partial-trace" non-linear sigma models, on the grounds of a fully symmetry-based procedure. After the general scheme is sketched, the particular example of a particle on the two-sphere is explicitly developed. As a remarkable feature, no explicit constraint treatment is required nor ordering ambiguities do appear. Moreover, the energy spectrum is recovered without extra terms in the curvature of the sphere.
