【摘要】 令二能级系统在绝热近似条件下演化一个周期后,得到了其所满足的循回条件是为整数之比,并计算了在该条件下系统中的3种量子相位。对比了二能级系统在绝热条件和非绝热条件下的几何相位结果,得到了二能级系统所满足的绝热近似条件是ω/Ω→0.更多还原

【Abstract】 In the adiabatic approximation the evolution of a periodic condition to two level systems, got the satisfied cycle the condition is as integer ratio, and calculated under the condition of the system in three kinds of quantum phase. Compared the results of two-level system, the geometric phase under adiabatic conditions and non-adiabatic conditions, has been a two-level system to meet the adiabatic approximation is.更多还原
