Symmetry-enforced Weyl phonons
Q. Liu, Y. Qian, et al.
This groundbreaking research, conducted by Qing-Bo Liu, Yuting Qian, Hua-Hua Fu, and Zhijun Wang, reveals the emergence of Weyl points in bosonic systems, specifically phonons, due to nonsymmorphic symmetries. They identify K₂Sn₂O₃ as a notable example, showcasing monopole WPs at the Brillouin zone boundary, providing a pathway for experimental exploration.
