有限维离散相空间广义不确定原理的初步考虑

First considerations on the generalized uncertainty principle for finite-dimensional discrete phase spaces

Marcelo A Marchiolli, Maurizio Ruzzi

摘要:

广义不确定原理和时空连续统的破缺无疑代表了在著名的普朗克尺度附近与量子引力和黑洞物理学有关的各种方法得出的两个重要结果。空间的离散性特别表明,所有可测量的长度都以基本尺度(在这种情况下,普朗克长度)为单位量子化。在这里,我们提出了一个自洽的理论框架,一类重要的物理系统的特点是有限的状态空间,并表明,这样的框架扩大了以前的知识广义不确定原理,在有限维离散相空间的拓扑效应发挥作用。此外,我们还研究了广义不确定原理(GUP)在什么情况下有效及其固有的局限性。

英文摘要:

Generalized uncertainty principle and breakdown of the spacetime continuum certainly represent two important results derived of various approaches related to quantum gravity and black hole physics near the well-known Planck scale. The discreteness of space suggests, in particular, that all measurable lengths are quantized in units of a fundamental scale (in this case, the Planck length). Here, we propose a self-consistent theoretical framework for an important class of physical systems characterized by a finite space of states, and show that such a framework enlarges previous knowledge about generalized uncertainty principles, as topological effects in finite-dimensional discrete phase spaces come into play. Besides, we also investigate under what circumstances the generalized uncertainty principle (GUP) works out well and its inherent limitations.
