动量空间中自由粒子薛定谔方程的局域相不变性

Local phase invariance of the free-particle Schrodinger equation in momentum space

Boyan Obreshkov

摘要:

利用自由粒子动量空间薛定谔方程的局域相不变性,构造了描述粒子在U(1)外规范场背景中运动的量子运动学.粒子动量空间的规范结构被解释为粒子携带的螺旋度和自旋。作为副产品,导出了带螺旋粒子在外势场中的有效单粒子薛定谔方程。预测了外势的屏蔽效应,它可以影响粒子的量子化和能级分裂。

英文摘要:

The local phase-invariance of the momentum-space Schrödinger equation for free-particle has been used to construct quantum kinematics that describes a motion of the particle in external U(1) background gauge field. The gauge structure over the momentum space of the particle is interpreted in terms of helicity and spin carried by the particle. As a by-product an effective one-particle Schrödinger equation of motion for the helicity-carrying particle in external potential field is derived. An effect of screening of the external potential is predicted, that can affect quantization and splittings of energy levels of the particle.
