研究了在垂直磁场和面内弱电场作用下二维运动电子的点相互作用产生的局域杂质态的量子动力学。所有的杂质态在电场的存在下都是不稳定的。计算了它们的寿命，并表明随着电场趋于零，它们以高斯方式增长。
We study the quantum dynamics of localized impurity states created by a point interaction for an electron moving in two dimensions under the influence of a perpendicular magnetic field and an in-plane weak electric field. All impurity states are unstable in presence of the electric field. Their lifetimes are computed and shown to grow in a Gaussian way as the electric field tends to zero.
