Singularity-free quantum tracking control of molecular rotor orientation

Alicia Magann, Tak-San Ho, Herschel Rabitz

摘要:

量子跟踪控制的目的是识别所施加的场,以引导特定观测量的期望值沿着期望的路径及时。相关的时间场可以通过反演观测量的基本动力学方程来确定。然而,以这种方式发现的领域往往受到不希望的奇点的困扰。在本文中,我们考虑一个平面分子转子,并推导出无奇跟踪表达式的字段,引导期望的转子的方向沿所需的轨迹在时间上。模拟,利用两个正交的控制电场,以驱动转子的方向沿一系列指定的轨道。

英文摘要:

Quantum tracking control aims to identify applied fields to steer the expectation values of particular observables along desired paths in time. The associated temporal fields can be identified by inverting the underlying dynamical equations for the observables. However, fields found in this manner are often plagued by undesirable singularities. In this paper we consider a planar molecular rotor, and derive singularity-free tracking expressions for the fields that steer the expectation of the orientation of the rotor along desired trajectories in time. Simulations are presented that utilize two orthogonal control electric fields to drive the orientation of the rotor along a series of designated tracks.
