三维引力的广义不确定原理与BTZ黑洞

Generalized Uncertainty Principle in three-dimensional gravity and the BTZ black hole

Alfredo Iorio, Gaetano Lambiase, Pablo Pais, Fabio Scardigli

摘要:

本文研究了引力诱导的广义不确定原理在三维空间中的结构。通过考虑引力半径$R_g$(即量子力学局域化过程的最小长度/最大分辨率)的不同可能候选者,适当地考虑了低维引力的微妙之处及其与四维和高维的重要差异。我们发现$M \neq 0$ Bañados-Teitelboim-Zanelli微黑洞的事件视界具有最一致的$R_g$ .这使我们能够得到一个合适的公式,广义不确定原理在三维空间中,也估计的修正引起的霍金温度和贝肯斯坦熵。我们还指出极端$M=0$的情况下,它的自然长度单位引入的宇宙学常数,$\ell = 1 / \sqrt{-Λ}$,作为一个可能的替代$R_g$,并提出了一个凝聚态模拟实现这种情况。

英文摘要:

We investigate the structure of the gravity-induced Generalized Uncertainty Principle in three dimensions. The subtleties of lower dimensional gravity, and its important differences with respect to four and higher dimensions, are duly taken into account, by considering different possible candidates for the gravitational radius, $R_g$, that is the minimal length/maximal resolution of the quantum mechanical localization process. We find that the event horizon of the $M \neq 0$ Bañados-Teitelboim-Zanelli micro black hole furnishes the most consistent $R_g$. This allows us to obtain a suitable formula for the Generalized Uncertainty Principle in three dimensions, and also to estimate the corrections induced by the latter on the Hawking temperature and Bekenstein entropy. We also point to the extremal $M=0$ case, and its natural unit of length introduced by the cosmological constant, $\ell = 1 / \sqrt{-Λ}$, as a possible alternative to $R_g$, and present a condensed matter analog realization of this scenario.
