论文摘要
我们提出了一个可解决的模型，该模型的氮气离子（NV）中心自旋（量子自旋）的混合量子古典系统与纳米抗逆转录器（经典）耦合，并分析对量子旋转动力学的常规或混乱的经典动力学的实施。我们在本文中重点的主要问题是，经典的动态混乱是否会在量子自旋动力学中诱导混乱效应。我们探讨了量子混乱的几个特征标准，例如量子庞加莱复发，一致性和能级分布的产生，并观察到自旋动力学中有趣的混乱效应。通过踢脉冲在悬臂动力学中施加的动力混乱会在量子子系统上引起随机动力学。我们考虑了两个和三个级别的量子系统，并表明在两级情况下，随机性类型并不符合量子混乱的所有特征特征，并且与之不同。我们还探讨了量子反馈对悬臂和整个系统动力学的影响。
We present an exactly solvable model of a hybrid quantum-classical system of a Nitrogen-Vacancy (NV) center spin (quantum spin) coupled to a nanocantilever (classical) and analyze the enforcement of the regular or chaotic classical dynamics onto the quantum spin dynamics. The main problem we focus in this paper is whether the classical dynamical chaos may induce chaotic effects in the quantum spin dynamics or not. We explore several characteristic criteria of the quantum chaos, such as quantum Poincaré recurrences, generation of coherence and energy level distribution and observe interesting chaotic effects in the spin dynamics. Dynamical chaos imposed in the cantilever dynamics through the kicking pulses induces the stochastic dynamics on the quantum subsystem. We consider a quantum system of two and three levels and show that in a two-level case, type of stochasticity is not conforming all the characteristic features of the quantum chaos and is distinct from it. We also explore the effect of quantum feedback on dynamics of the cantilever and the entire system.
