从非平衡量子统计力学出发的微系统物理

Physics of a microsystem starting from non-equilibrium quantum statistical mechanics

L. Lanz, O. Melsheimer, B. Vacchini

摘要:

在本文中,我们解决这个问题,给一个具体的支持的想法,最初源于尼尔斯玻尔,量子力学必须植根于物理学的宏观系统。它表明,从形式主义的非平衡统计算子,这是现在的一个巩固的一部分,量子统计力学,两个孤立系之间的特定相关性可以被挑出来,并解释为微系统。以这种方式也建立了一个新的框架,在其中可以自然地解决退相干的问题。

英文摘要:

In this paper we address the problem to give a concrete support to the idea, originally stemming from Niels Bohr, that quantum mechanics must be rooted inside the physics of macroscopic systems. It is shown that, starting from the formalism of the non-equilibrium statistical operator, which is now a consolidated part of quantum statistical mechanics, particular correlations between two isolated systems can be singled out and interpreted as microsystems. In this way also a new framework is established in which questions of decoherence can be naturally addressed.
