原子和固态系统中的模拟黑洞事件视界
Mimicking black hole event horizons in atomic and solid-state systems
摘要:
全息量子物质展示了量子黑洞和更传统的(尽管相互作用很强)量子多体系统之间有趣的联系。这种联系表现在它们的热力学、统计力学和多体量子混沌的研究中。在解释了其中的一些联系及其意义之后,我们将重点放在迄今为止全息量子物质最有希望的例子上,即Sachdev-Ye-Kitaev(SYK)模型家族。这些都是简单的量子力学模型,被认为可以全息地实现量子黑洞。我们审查和评估SYK模型的实验实现的各种建议。这样的实验实现提供了令人兴奋的前景,访问黑洞物理,从而解决许多神秘的问题,在量子引力,在桌面实验。
英文摘要:
Holographic quantum matter exhibits an intriguing connection between quantum black holes and more conventional (albeit strongly interacting) quantum many-body systems. This connection is manifested in the study of their thermodynamics,statistical mechanics and many-body quantum chaos. After explaining some of those connections and their significance, we focus on the most promising example to date of holographic quantum matter, the family of Sachdev-Ye-Kitaev (SYK) models. Those are simple quantum mechanical models that are thought to realize, holographically, quantum black holes. We review and assess various proposals for experimental realizations of the SYK models. Such experimental realization offers the exciting prospect of accessing black hole physics, and thus addressing many mysterious questions in quantum gravity, in tabletop experiments.
