从费曼形式论看非对易量子力学

Noncommutative Quantum Mechanics Viewed from Feynman Formalism

J. Lages, A. Berard, H. Mohrbach, Y. Grandati, P. Gosselin

摘要:

戴森在1990年出版了一份证明,由于费曼的麦克斯韦方程组。这个证明是基于位置和速度之间的简单交换关系的假设。我们首先研究一个非相对论性粒子使用费曼形式主义。证明了Poincaré磁角动量和Dirac磁角动量是Feynman形式的sO(3)李代数结构的直接结果.然后,我们展示了如何将这种形式主义的对偶动量空间的目的是引入非对易量子力学,这是最近的主题,从粒子物理学到凝聚态物理的广泛的工作。

英文摘要:

Dyson published in 1990 a proof due to Feynman of the Maxwell equations. This proof is based on the assumption of simple commutation relations between position and velocity. We first study a nonrelativistic particle using Feynman formalism. We show that Poincaré's magnetic angular momentum and Dirac magnetic monopole are the direct consequences of the structure of the sO(3) Lie algebra in Feynman formalism. Then we show how to extend this formalism to the dual momentum space with the aim of introducing Noncommutative Quantum Mechanics which was recently the subject of a wide range of works from particle physics to condensed matter physics.
