地平表面张力
Surface tension of the horizon
摘要:
将黑洞视界视为具有表面张力的拉伸膜的想法由来已久。本文讨论了引力子的玻色-爱因斯坦凝聚体空间量子图像中视界表面张力的微观起源。视界是引力子的一个相界面,其表面张力是由其两侧引力子之间相互作用强度的差异引起的。引力源,如史瓦西黑洞,通过改变周围引力子的能量和分布来创造一个过渡区。阿基米德的引力原理可以表述如下:“物体上的引力等于它所移动的引力子的重量。"
英文摘要:
The idea of treating the horizon of a black hole as a stretched membrane with surface tension has a long history. In this work, we discuss the microscopic origin of the surface tension of the horizon in quantum pictures of spaces, which are Bose-Einstein condensates of gravitons. The horizon is a phase interface of gravitons, the surface tension of which is found to be a result of the difference in the strength of the interaction between the gravitons on its two sides. The gravitational source, such as a Schwarzschild black hole, creates a transitional zone by changing the energy and distribution of its surrounding gravitons. Archimedes' principle for gravity can be expressed as follows: "the gravity on an object is equal to the weight of the gravitons that it displaces."
