量子非定态薛定谔演化的非循环几何位相

The NonCyclic Geometric Phases of Non Stationary States in Schrdinger Evolution

证明了量子体系中任何非定态的演化，无论是循环演化还是非循环演化，都可能导致几何位相的出现．作为例子，具体计算了旋转磁场中１／２自旋粒子运动的绝热态及绝热叠加态在演化过程中几何位相．

It is shown that the geometric phase appearing when the non stationary state evolves according to the cyclical or non cyclical Schrdinger equation. As an example, we calculate the geometric phases of the adiabatic state and the superposition of the adiabatic states for a spin 1/2 particle processing in a time dependent rotational magnetic field.
