Berry几何相与量子跃迁

Berry Geometric Phase and Quantum Transition

针对Ｂｅｒｒｙ几何相的出现所关联的量子能级，微弱变化跃迁的物理背景条件进行分析研究；对严格产生（获得）Ｂｅｒｒｙ几何相与这种微弱变化跃迁之间的内在关系作进一步探讨．结果表明： Ｂｅｒｒｙ几何相的严格产生都是由系统在演变过程中所出现的量子能级微弱变化跃迁的绝热极限效应所必然导致的结果．

For the emergence of Berry geometric phase, we analyze the relevant physical background condition of the weak transitions among quantum energy-levels. We elaborate a further discussion on the internal relationship between the strict obtainment of Berry geometric phase and the weak transitions. Our study shows that the strict obtainment of Berry geometric phase is the natural result of the adiabatic limit effect of weak transitions among quantum energy-levels. These transitions occur inevitably during the evolution process of quantum system.
