Jan Govaerts, M. Norbert Hounkonnou, Habatwa V. Mweene

摘要:

本文从不同的观点重新考虑了带电粒子在垂直均匀静磁场作用下平面内的普通朗道问题。的作用相空间的正则变换和它们的关系,以选择规范的解决方案中的问题。朗道问题,然后扩展到不同的情况下,特别是一个纯粹的线性潜在的长期被添加为相互作用的奇异情况下,一个完整的纯代数解决方案。这个解决方案,然后利用解决这个相同的奇异朗道问题的半平面,作为动机的潜在相关性,这样的几何量子霍尔测量的存在下,一个电场或引力量子阱。

英文摘要:

The ordinary Landau problem of a charged particle in a plane subjected to a perpendicular homogeneous and static magnetic field is reconsidered from different points of view. The role of phase space canonical transformations and their relation to a choice of gauge in the solution of the problem is addressed. The Landau problem is then extended to different contexts, in particular the singular situation of a purely linear potential term being added as an interaction, for which a complete purely algebraic solution is presented. This solution is then exploited to solve this same singular Landau problem in the half-plane, with as motivation the potential relevance of such a geometry for quantum Hall measurements in the presence of an electric field or a gravitational quantum well.
