无旋转波近似的脉冲设计

Pulse design without rotating wave approximation

S. Ibáñez, Yi-Chao Li, Xi Chen, J. G. Muga

摘要:

我们设计了可实现的含时半经典脉冲,当双折射波近似不能应用时,可以比超快地反转二能级系统的布居数。基于反绝热方法或不变量的不同方法可能会导致脉冲函数的奇异性。提出了在脉冲宽度较小的情况下避免或消除奇异性的方法。对于许多振荡的另一种数值最小化方法的建议和证明。

英文摘要:

We design realizable time-dependent semiclassical pulses to invert the population of a two-level system faster than adiabatically when the rotating-wave approximation cannot be applied. Different approaches, based on the counterdiabatic method or on invariants, may lead to singularities in the pulse functions. Ways to avoid or cancel the singularities are put forward when the pulse spans few oscillations. For many oscillations an alternative numerical minimization method is proposed and demonstrated.
