旋子系统可控性研究

Controllability of spin-boson systems

Ugo Boscain, Paolo Mason, Gianluca Panati, Mario Sigalotti

AI总结:

本文研究旋子系统可控性,通过几何控制技术和扰动理论证明了在几乎所有相互作用参数值下系统的近似可控性。

摘要:

本文研究所谓的旋子系统,即一个两能级系统与量化玻色场的特定模式相互作用。我们简要描述了受控的拉比和Jaynes-Cummings模型,并讨论它们在数学和物理文献中的出现。然后研究了当控制是一个外部场作用于玻色部分时的拉比模型可控性。应用几何控制技术到伽辽金近似,并利用扰动理论保证漂移算子谱的非共振性,证明了系统在几乎所有相互作用参数值下的近似可控性。

英文摘要:

In this paper we study the so-called spin-boson system, namely {a two-level system} in interaction with a distinguished mode of a quantized bosonic field. We give a brief description of the controlled Rabi and Jaynes--Cummings models and we discuss their appearance in the mathematics and physics literature. We then study the controllability of the Rabi model when the control is an external field acting on the bosonic part. Applying geometric control techniques to the Galerkin approximation and using perturbation theory to guarantee non-resonance of the spectrum of the drift operator, we prove approximate controllability of the system, for almost every value of the interaction parameter.
