Elias C. Vagenas, Ahmed Farag Ali, Mohammed Hemeda, Hassan Alshal

摘要:

在本文中,我们研究了无质量的Reissner-Nordstrom de Sitter度规在最小长度的情况下。我们不仅证明了无质量带电粒子(费米子和玻色子)的能量密度的局限性,而且证明了它们穿越宇宙视界的能力。这些无质量粒子可能与狄拉克海相互作用,在这种情况下,它们将出现在dS/CFT全息的宇宙视界之外。这一结果可能是狄拉克海膨胀的一个根本原因。因此,时空大挤压可能会发生。

英文摘要:

In this paper, we investigate the massless Reissner-Nordstrom de Sitter metric in the context of minimal length scenarios. We prove not only the confinement of the energy density of massless charged particles, both fermions and bosons, but also their ability to tunnel through the cosmological horizon. These massless particles might be interacting with Dirac sea and in this case they will appear outside the cosmological horizon in the context of dS/CFT holography. This result may formulate a fundamental reason for the expansion of the Dirac sea. Therefore, a spacetime Big Crunch may occur.
