量子-经典杂化系统的线性动力学

Linear dynamics of quantum-classical hybrids

Hans-Thomas Elze

摘要:

提出了一种量子-经典混合动力学的形式,它涉及经典和量子力学自由度的直接耦合。它对量子力学近似方案中的应用很感兴趣,并且可能与量子力学的基础有关,特别是当涉及到探索量子经典边界的实验时。目前的线性理论不同于霍尔和Reginatto的非线性系综理论,但与它的股份,以满足所有的一致性要求,在文献中讨论,而早期的尝试失败,在这方面。我们的工作是基于A。Heslot,表明概念的国家在相空间,可观的,泊松括号,和相关的正则变换可以自然地扩展到量子力学。这一点在这里被适当地推广到量子-经典混合体。

英文摘要:

A formulation of quantum-classical hybrid dynamics is presented, which concerns the direct coupling of classical and quantum mechanical degrees of freedom. It is of interest for applications in quantum mechanical approximation schemes and may be relevant for the foundations of quantum mechanics, in particular, when it comes to experiments exploring the quantum-classical border. The present linear theory differs from the nonlinear ensemble theory of Hall and Reginatto, but shares with it to fullfill all consistency requirements discussed in the literature, while earlier attempts failed in this respect. Our work is based on the representation of quantum mechanics in the framework of classical analytical mechanics by A. Heslot, showing that notions of states in phase space, observables, Poisson brackets, and related canonical transformations can be naturally extended to quantum mechanics. This is suitably generalized for quantum-classical hybrids here.
