Fermion-induced quantum critical points
Zi-Xiang Li, Yi-Fan Jiang, Shao-Kai Jian +1
A unified theory of quantum critical points beyond the conventional Landau-Ginzburg-Wilson paradigm remains unknown. According to Landau cubic criterion, phase transitions should b…
Topological photonic crystal with equifrequency Weyl points
Luyang Wang, Shao-Kai Jian, Hong Yao
Weyl points in three-dimensional photonic crystals behave as monopoles of Berry flux in momentum space. Here, based on general symmetry analysis, we show that a minimal number of f…
Symmetry-protected ideal Weyl semimetal in HgTe-class materials
Jiawei Ruan, Shao-Kai Jian, Hong Yao +3
Ideal Weyl semimetals with all Weyl nodes exactly at the Fermi level and no coexisting trivial Fermi surfaces in the bulk, similar to graphene, could feature deep physics such as e…
Correlated double-Weyl semimetals with Coulomb interactions: possible applications to HgCr2Se4 and SrSi2
Shao-Kai Jian, Hong Yao
We study the fate of double-Weyl fermions in three-dimensional systems in the presence of long-range Coulomb interactions. By employing the momentum-shell renormalization group app…
