Decoupled squeezed states for the Landau System (planar charged particle moving in a uniform magnetic field) are builded. It is convenient to use these states to describe the circular motion of the charged particle. The results obtained do not depend on gauges.
摘要 在Landau规范下计算出均匀磁场中带电粒子的圆心相干态。利用这些圆心相干态可方便地描述带电粒子的圆周运动。这些圆周运动与经典力学的结果比较表明,圆心相干态描述系综中的平均运动. Abstract Under Landau gauge center coherent states of charged particles in a uniform magnetic field are derived. It is convenient by use of these coherent states to describe the circular motion of charged particles in the field. The comparison between the circular motion and the result of classical mechanics shows that a center coherent state describes the averaged motion of an ensemble. 作者及机构信息 黄湘友1, 田旭3, 胡城立2 (1)北京大学物理系; (2)湖南大学机械系; (3)华中理工大学激光技术国家重点实验室 基金项目: 国家自然科学基金资助的课题.
