饱和量子测不准关系的量子几何:(Q,P)Heisenberg观测量的情形

Towards the Quantum Geometry of Saturated Quantum Uncertainty Relations: The Case of the (Q,P) Heisenberg Observables

Jan Govaerts

摘要:

对本研讨会论文集的这一贡献概述了一个确定几何结构的一般方案-从中也可能恢复量子动力学-与希尔伯特空间中量子态的流形有关,这些量子态使薛定谔-罗伯逊不确定性关系饱和,而薛定谔-罗伯逊不确定性关系与一组特定的量子观测值有关,这些量子观测值描述了一个给定的量子系统及其动力学。在这种探索的第一步是解决在这里的情况下,观察量Q和P的海森堡代数的一个单自由度系统。相应的饱和态是众所周知的一般压缩态,其性质进行了详细的审查和讨论,连同一些原始的结果,在准备的研究推迟到一个单独的分析其量子几何和相应的路径积分表示在这样的国家。

英文摘要:

This contribution to the present Workshop Proceedings outlines a general programme for identifying geometric structures--out of which to possibly recover quantum dynamics as well--associated to the manifold in Hilbert space of the quantum states that saturate the Schrödinger-Robertson uncertainty relation associated to a specific set of quantum observables which characterise a given quantum system and its dynamics. The first step in such an exploration is addressed herein in the case of the observables Q and P of the Heisenberg algebra for a single degree of freedom system. The corresponding saturating states are the well known general squeezed states, whose properties are reviewed and discussed in detail together with some original results, in preparation of a study deferred to a separated analysis of their quantum geometry and of the corresponding path integral representation over such states.
