标题： Hawking radiation in optics and beyond

摘要： 霍金辐射最初是在天体物理学中提出的，但已被推广和扩展到其他物理系统，并被称为类比霍金辐射。 在过去二十年中，已经进行了多次在实验室中测量它的尝试，其中最成功的系统之一是光学系统。 光在介电材料中的相互作用会导致类比霍金效应，事实上，其受激发版本已经检测到，而对自发信号的搜索目前正在继续。 我们简要回顾霍金辐射的一般推导，然后专注于光学类比并展示一些新的数值结果。 最后，我们呼吁对霍金辐射这一术语进行推广。 显示英文摘要

摘要： Hawking radiation was originally proposed in astrophysics, but it has been generalized and extended to other physical systems receiving the name of analogue Hawking radiation. In the last two decades, several attempts have been made to measure it in a laboratory, one of the most successful systems is in optics. Light interacting in a dielectric material causes an analogue Hawking effect, in fact, its stimulated version has already been detected and the search for the spontaneous signal is currently ongoing. We briefly review the general derivation of Hawking radiation, then we focus on the optical analogue and present some novel numerical results. Finally, we call for a generalization of the term Hawking radiation.
