本文提出了一种描述回旋加速器运动中心坐标动力学的有效哈密顿量。利用长程随机势的有效哈密顿量研究了朗道子带的尾态。特别是在尾部的态密度是通过WKB近似得到的。用经典逾渗理论对迁移率边缘进行了粗略估计，并与实验结果进行了比较。
An effective Hamiltonian to describe the dynamics of the center coordinates of the cyclotron motion is presented. The tail states of the Landau subbands are investigated by means of the effective Hamiltonian for the case of long-range random potentials. Especially the state density in the tail is obtained by the WKB approximation. The mobility edge is roughly estimated by the classical percolation theory and compared with experimental results.
