In recent years, there has been a great deal of interest in predicting Weyl physics in phonons due to the unique properties of topological phonons. In this study, we postulate that ZrS2 is a candidate material with multiple Linear Weyl point (LWP) ph

Abstract Weyl phonons have long been regarded as an important kind of topological bosonic quasiparticle states. Previous investigations in this field mainly focus on Weyl phonons located at high‐symmetry points (HSPs) in Brillouin zone (BZ), while

Exploration of topological phonons in two-dimensional (2D) has long been regarded as one of the central topics in topological physics. Due to their distinct band dispersion, hourglass nodal rings have garnered considerable attention, but their existe

In topology physics, the prediction of Weyl systems with the minimum nonzero number of Weyl points (WPs) remains challenging. In this study, for the first time, we propose the P312 type RbGeIO6 as a material candidate with the minimum number of WPs i

Abstract Absence of any surface arc state has been regarded as the fundamental property of singular Weyl points, because they are circumvented from the Nielsen‐Ninomiya no‐go theorem. In this work, through systematic investigations on topological

A recent study reported the enhancement of thermoelectric response due to the presence of triple point phonons [Phys. Rev. Mater 2, 114204 (2018)]. Because the topological triple point phonons field is still at its early stage, it is necessary to sea

Recently, there has been significant interest in exploring the chiral quasiparticles in phonons, which describe the atomic lattice vibrations in solids. In this work, using first-principle calculation, we select a realistic material Na2Zn2O3 as an ex
