双重复制：从光学到量子引力
The double copy: from optics to quantum gravity
摘要：
最近，在电磁学和引力理论之间发现了一种有趣的关系（“双重复制”）。这可能为我们提供了一种思考引力的新方法，也有一些实际应用，包括有效计算引力观测值，以及如何使用光学系统模拟引力。在本教程中，我们将回顾关于双拷贝的已知知识，并认为现在是光学和/或凝聚态研究人员对这种迷人的对应感兴趣的最佳时机。
英文摘要：
Recently, an intriguing relationship (the "double copy") has been discovered between theories like electromagnetism, and gravity. This potentially gives us a new way to think about gravity, and there are also practical applications involving the efficient calculation of gravitational observables, and also how to simulate gravity using optical systems. In this tutorial, we will review what is known about the double copy, and argue that now is the perfect time for researchers in optics and / or condensed matter to become interested in this fascinating correspondence.
