摘要

量子理论与引力基本原理的结合导致了对不确定性原理的修正。在这项研究中,我们采用了扩展不确定性原理(EUP),其最大长度来自宇宙学粒子视界。我们在一个非相互作用电子气体系统中研究了这种特定修改的影响。我们分析推导出了退化压力和体积模量的广义关系。一个有趣的发现是,退化压力减小了,这一点可以从观测到的白矮星的大小得到证实,它比标准理论预测的要小。尽管如此,它仍然能够为防止引力坍缩提供支持。

Degeneracy pressure in the presence of maximum length for non-interacting electrons

Combining quantum theory with the fundamental principles of gravity results in the modification of the uncertainty principle. In this study, we employ the extended uncertainty principle (EUP) with the maximum length derived from the cosmological particle horizon. The impact of this specific kind of modification is examined in a non-interacting electron gas system. We analytically derive the generalized relations for the degeneracy pressure and the bulk modulus. An intriguing finding is that the degeneracy pressure is reduced, as confirmed by the observed size of white dwarfs, which is smaller than what is predicted by the standard theory. Nevertheless, it is still capable of providing support against gravitational collapse.
