论文摘要
我们在存在强大的磁场和平面电场的存在下并且在二维无序系统内的情况下得出了电流公式。该电流起源于指南中心坐标跳跃。在强磁场状态下，可以将电流描绘为中心坐标的迁移。在电子杂质散射期间，引导中心突然改变了它们的坐标。由于电场，坐标偏移积累有助于纵向电流。在散射过程中，回旋子半径的值会变化，从而补偿了坐标跳跃过程中电势能的变化。回旋子半径的转移是依赖电场的经典表现，依赖于Landau水平的拓宽和转移。
We derived an electrical current formula in the presence of a strong out of plane magnetic field and an in plane electric field, and within two dimensional disordered systems. This current is originated from the guiding center coordinate jump. At a strong magnetic field regime, the current can be pictured as the migration of the center coordinates. During the electron impurity scattering, the guiding centers suddenly shift their coordinates. Because of the electric field, the coordinate shift accumulatively contributes to a longitudinal current. During the scattering, the value of cyclotron radius changes, which compensates for the change of the electric potential energy during the coordinate jump. The diversion of cyclotron radius is the classical manifestation of electric field dependent broadening and shifting of the Landau levels.
