摘要: 根据绝热捷径技术设计一种添加非厄米反向透热Hamilton量的方法, 并研究非旋波近似下的两能级量子系统. 结果表明: 该Hamilton量具有非平衡的增益耗散项, 可实现布居数完全转移; 该方法对参数具有较强的鲁棒性; 增大不平衡的增益耗散比率可大幅度缩短演化时间.

关键词: 非厄米Hamilton量, 绝热捷径技术, 非旋波近似

Abstract: According to a shortcut to adiabatic technique, we designed a method to add nonHermitian reverse heating Hamiltonian 
to study twolevel quantum systems without rotatingwave approximation. The results show that the Hamilton has an unbalanced gain dissipation term, can realize complete transfer of population, the method has strong robustness to parameters, 
and increasing the unbalanced gain dissipation ratio can greatly shorten the evolution time.

Key words: non-Hermitian Hamiltonian, shortcut to adiabatic technique, without rotatingwave approximation
