Quantum-classical correspondence for a charge in a uniform magnetic field

  • Online:2010-03-25 Published:2010-03-20

摘要: 荷电粒子在均匀磁场中的运动是螺旋线,在垂直于磁场的平面内为圆轨道.在量子力学中,可以利用规范变换将这个经典圆轨道关系的算符形式推导出来.

关键词: 量子力学, 规范变换, 相位因子, 量子经典对应

Abstract: The motion of a charged particle in a uniform magnetic field forms a helical curve. In the plane perpendicular to the magnetic field, the orbit is a circular. In quantum mechanics, the operator form of the classical circle relations by gauge transformation is derived.

Key words: quantum mechanics, gauge transformation, phase factor, quantum-classical correspondence
