Transitionless quantum drivings for the harmonic oscillator

J. G. Muga, X. Chen, Ibáñez, I. Lizuain, A. Ruschhaupt

摘要:

描述了在有限时间内无跃迁地改变量子谐振子频率的两种方法,并对这两种方法进行了比较。第一种方法,无跃迁跟踪算法,利用广义谐振子和非局部势。第二种方法,基于工程的运动不变量,只修改谐波频率的时间,保持潜在的本地在任何时候。

英文摘要:

Two methods to change a quantum harmonic oscillator frequency without transitions in a finite time are described and compared. The first method, a transitionless-tracking algorithm, makes use of a generalized harmonic oscillator and a non-local potential. The second method, based on engineering an invariant of motion, only modifies the harmonic frequency in time, keeping the potential local at all times.
