摘要
计算出了二能级系统在非绝热近似情形下的演化波函数,同时计算出了系统在演化一周期后的几何相位。对比绝热近似时的情形,给出一种二能级系统的绝热近似条件。
We obtain the wavefunction of the two states system in non-adiabatic condition by using the method of coordinate transformation. The geometric phase of the system is also discussed after an evolution period. We present the adiabatic condition of two states system after contraated it with adiabatic models.
