Recipe for single-pair-Weyl-points phonons carrying the same chiral charges
Guangqian Ding, Chengwu Xie, Jingbo Bai +3
Recently, Wang et al. [Phys. Rev. B, 106, 195129 (2022)] challenged a widely held belief in the field of Weyl physics, demonstrating that single-pair-Weyl-points (SP-WPs) can exist…
