二维带电粒子运动的Noether对称性

Noether symmetries for two-dimensional charged particle motion

F. Haas, J. Goedert

摘要:

我们发现了非相对论二维带电粒子运动的Noether点对称性。这些对称性是由一个准不变变换,一个时间相关的旋转和时间相关的空间平移。相关的电磁场满足一阶线性偏微分方程组。这个系统的精确求解,产生三类电磁场兼容的Noether点对称性。相应的Noether不变量的推导和解释。

英文摘要:

We find the Noether point symmetries for non-relativistic two-dimensional charged particle motion. These symmetries are composed of a quasi-invariance transformation, a time-dependent rotation and a time-dependent spatial translation. The associated electromagnetic field satisfy a system of first-order linear partial differential equations. This system is solved exactly, yielding three classes of electromagnetic fields compatible with Noether point symmetries. The corresponding Noether invariants are derived and interpreted.
