Analogs of fundamental physical phenomena can be used in two ways. One way consists in reproducing specific aspects of the classical or quantum gravity of quantum fields in curved space or of other high-energy scenarios on lower-energy corresponding systems. The “reverse way” consists in building fundamental physical theories, for instance, quantum gravity models, inspired by the lower-energy corresponding systems. Here, we present the case of graphene and other Dirac materials.

用类似物寻找量子引力：石墨烯案例

基本物理现象的类似物可以以两种方式使用。一种方法是在弯曲空间中再现量子场的经典或量子引力的特定方面，或在低能量相应系统上再现其他高能场景。“逆向方法”在于建立基础物理理论，例如，受低能量对应系统启发的量子引力模型。在这里，我们介绍了石墨烯和其他狄拉克材料的情况。
