摘要

巴罗提出,量子引力效应可能会给黑洞事件视界的面积带来分形修正。到目前为止,我们还不清楚这一假设是否能带来超越广义相对论的有意义的量子引力理论。在本文中,我们认为情况确实如此。特别是,假设 Δ 是一个径向函数,我们证明巴罗假说和雅各布森方法可以产生非微观的修正引力理论。

Modified gravity theories from the Barrow hypothesis
Barrow proposed that quantum gravity effects might introduce fractal corrections to the area of the event horizon of black holes. The area law gets modified as , with . It was so far unclear whether this assumption could lead to meaningful quantum gravity theories beyond general relativity. In this paper, we argue that this is indeed the case. In particular, assuming Δ to be a radial function, we show that the Barrow hypothesis, together with Jacobson's approach can generate non-trivial modified gravity theories.

期刊介绍: General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
