High-chirality and multiquaternion Weyl nodes in hexagonal ReO
Siyu Chen, Robert-Jan Slager, Bartomeu Monserrat +1
The formation of two-band nodal points in gapless topological phases, referred to as conventional Weyl nodes, relies solely on translational symmetry. However, when coupled with ot…

Coexisting Euler and Stiefel-Whitney Topological Phases in Elastic Metamaterials
Jijie Tang, Adrien Bouhon, Yue Shen +6
The study of topological band theory in classical structures has led to the development of novel topological metamaterials with intriguing properties. While single-gap topologies a…
