库仑场和磁场中平面Dirac电子的准精确可解性

Quasi-exact Solvability of Planar Dirac Electron in Coulomb and Magnetic Fields

Chun-Ming Chiang, Choon-Lin Ho

摘要:

电子在库仑和均匀磁场中的二维狄拉克方程是准精确可解系统的一个物理例子。然而,该模型不属于基于代数$sl(2)$的类,该代数是大多数一维和有效一维准精确可解系统的基础。本文证明了拟精确可解微分方程具有一个隐藏的$osp(2,2)$超代数。

英文摘要:

The Dirac equation for an electron in two spatial dimensions in the Coulomb and homogeneous magnetic fields is a physical example of quasi-exactly solvable systems. This model, however, does not belong to the classes based on the algebra $sl(2)$ which underlies most one-dimensional and effectively one-dimensional quasi-exactly solvable systems. In this paper we demonstrate that the quasi-exactly solvable differential equation possesses a hidden $osp(2,2)$ superalgebra.
