Symmetric Hybrid Dynamics: A canonical formulation of coupled classical-quantum dynamics
摘要:
给出了耦合经典-量子动力学的正则形式。该理论被命名为对称混合动力学。证明了在一般条件下,它的预言与全量子预言是一致的。此外,对称混合动力学显示出完全一致的规范结构。即,它是建立在一个李代数的观察量,时间演化是酉和解决的混合型薛定谔方程。提出了一种从经典力学到混合动力学的量子化公式。量子化映射是一个李代数同构。最后简要地提出了该理论的一些可能的应用。
英文摘要:
A canonical formulation of coupled classical-quantum dynamics is presented. The theory is named symmetric hybrid dynamics. It is proved that under some general conditions its predictions are consistent with the full quantum ones. Moreover symmetric hybrid dynamics displays a fully consistent canonical structure. Namely, it is formulated over a Lie algebra of observables, time evolution is unitary and the solution of a hybrid type Schrödinger equation. A quantization prescription from classical mechanics to hybrid dynamics is presented. The quantization map is a Lie algebra isomorphism. Finally some possible applications of the theory are succinctly suggested.
