标题： Optical analogues of black-hole horizons

摘要： 霍金辐射不太可能从真正的黑洞中被测量到，但可以在实验室的类比中进行测试。 它被预测为量子力学和广义相对论的结果，但后来被证明更为普遍。 折射率扰动会产生一个光学类比的黑洞视界和由光组成的霍金辐射。 我们讨论了使用实践物理的光学类比的核心和最近实验。 我们强调了经典场、负频率、“常规光学”和色散的作用。 简要讨论了未来的机遇和挑战。 显示英文摘要

摘要： Hawking radiation is unlikely to be measured from a real black-hole, but can be tested in laboratory analogues. It was predicted as a consequence of quantum mechanics and general relativity, but turned out to be more universal. A refractive index perturbation produce an optical analogue of the black-hole horizon and Hawking radiation that is made of light. We discuss the central and recent experiments of the optical analogue, using hands-on physics. We stress the roles of classical fields, negative frequencies, 'regular optics' and dispersion. Opportunities and challenges ahead are shortly discussed.
