项目摘要

Nothing, not even light, can escape from a black hole due to extreme gravity. However, as was shown by Roger Penrose , massive particles entering the ergoregion just outside the event horizon can extract energy from a rotating black hole. We propose to explore this elusive, fascinating process in a table-top experimental quantum light-matter superfluid formed in a semiconductor microcavity polariton platform; this will emulate a rotating black hole in 2+1 dimensional analogue spacetime on a microscale. The research will capitalize on the highly favorable properties of the polariton system, such as the ability to undergo condensation and superfluidity due to the giant optical nonlinearity, as well as the ability to control, drive and measure the spatial density and phase of the 2D polaritons using external laser sources. These enable the "flow" of space-time in a black hole by a large draining vortex in a superfluid to be emulated, where the boundary of the transition from subsonic to supersonic flow recreates the event horizon. The particular focus of this proposal will be on the study of how the Penrose process is affected by the quantum behavior of the polariton fluid (described by macroscopic order) leading to quantization of orbital angular momentum of the analogue black hole. Overall our project addresses fundamental physics questions by exploiting state-of-the art semiconductor quantum technologies developed in the Physics Department and at the National Epitaxy Facility at the University of Sheffield: it relates general relativity to hydrodynamics and physics of macroscopically ordered light-matter states in solids and opens up new avenues in the study of quantum phenomena and gravity effects on the microscale.

没有任何东西，甚至连光都不能从黑洞中逃脱，因为它有着巨大的引力。然而，正如罗杰·彭罗斯（Roger Penrose）所展示的那样，进入视界外的能区的大质量粒子可以从旋转的黑洞中提取能量。我们建议在半导体微腔极化子平台中形成的桌面实验量子光物质超流体中探索这个难以捉摸的迷人过程;这将在微观尺度上模拟2+1维模拟时空中的旋转黑洞。该研究将利用极化激元系统的高度有利的特性，例如由于巨大的光学非线性而经历凝聚和超流性的能力，以及使用外部激光源控制，驱动和测量2D极化激元的空间密度和相位的能力。这使得黑洞中时空的“流动”能够通过超流体中的大型排水漩涡来模拟，其中从亚音速到超音速流动的过渡边界重新创建了事件视界。该提案的特别重点将是研究彭罗斯过程如何受到极化激元流体（由宏观序描述）的量子行为的影响，从而导致模拟黑洞的轨道角动量量子化。总的来说，我们的项目通过利用物理系和谢菲尔德大学国家外延设施开发的最先进的半导体量子技术来解决基本物理问题：它将广义相对论与流体力学和固体中宏观有序轻物质态的物理学联系起来，并开辟了量子现象和微观引力效应研究的新途径。
