Symmetry-constrained coexistence of charge-three and charge-one Weyl points in nonmagnetic crystals
Ze-Xin Xue, Ke-Xin Pang, Yun-Yun Bai +2
High-charge Weyl semimetals (WSMs), particularly those hosting charge-three Weyl point (C-3 WPs), have attracted considerable interest owing to their unconventional topological pro…

Symmetry-protected triplet Weyl complexes
Yun-Yun Bai, Ke-Xin Pang, Yan Gao +2
The Nielsen-Ninomiya theorem dictates that Weyl nodes must appear in pairs of opposite chirality to preserve global charge neutrality. However, in crystals, specific crystalline sy…

Symmetry-Protected Minimum of Four Conventional Weyl Points in Nonmagnetic Crystals
Ze-Xin Xue, Ke-Xin Pang, Yun-Yun Bai +3
Realizing nonmagnetic Weyl semimetals (WSMs) with the minimal number of conventional Weyl points (WPs) and a clean Fermi surface remains a central challenge. Here, combining symmet…
