第二类Weyl费米子和第二类狄拉克费米子可能出现在黑洞的视界后面。相应地，可以通过创建带有过度倾斜的Weyl或Dirac锥体的区域来模拟黑洞。黑洞内部电子态的填充伴随着霍金辐射。如果黑洞区域足够小，那么Weyl半金属的霍金温度可以达到室温，从而使视界上的有效引力很大。
The type-II Weyl and type-II Dirac fermions may emerge behind the event horizon of black holes. Correspondingly, the black hole can be simulated by creation of the region with overtilted Weyl or Dirac cones. The filling of the electronic states inside the “black hole” is accompanied by Hawking radiation. The Hawking temperature in the Weyl semimetals can reach the room temperature, if the black hole region is sufficiently small, and thus the effective gravity at the horizon is large.
