煎饼化与负霍金温度

Pancakification and negative Hawking temperatures

Tyler McMaken

AI总结:

本文研究黑洞内视界附近潮汐力由拉伸转为压缩所导致的“煎饼化”现象,并探讨霍金辐射在压缩潮汐力下预言负温度的可能性,以推进对内视界量子行为的半经典理解。

摘要:

带电或旋转黑洞的真空模型具有两个视界,其中内视界有一个常被忽视的性质:引力潮汐力最初会将自由下落的观测者“意大利面条化”,但最终会改变符号,将观测者像煎饼一样压扁。内视界还会引发一种被称为“质量暴胀”的经典蓝移不稳定性,而最近的多项研究发现,内视界表现出更强的量子奇异行为。在本文中,我们探讨霍金辐射的量子效应,在压缩性潮汐力存在的情况下,该效应似乎预言了负温度。通过分析量子场与黑洞几何的相互作用,我们可以对内视界附近实际发生的情况获得更接近半经典的理解。

英文摘要:

Vacuum models of charged or spinning black holes possess two horizons, the inner of which has the oft-overlooked property that gravitational tidal forces initially spaghettifying a freely falling observer will eventually change signs and flatten the observer like a pancake. Inner horizons also induce a classical blueshift instability known as mass inflation, and a number of recent studies have found that inner horizons exhibit even stronger quantum singular behavior. In this essay we explore the quantum effect of Hawking radiation, which in the presence of compressive tidal forces seems to predict negative temperatures. By analyzing the interaction of quantum fields with black hole geometries, we can come to a closer semiclassical understanding of what really happens near a black hole's inner horizon.
