Symmetry Criterion for Van Hove Criticality at Non-Time-Reversal-Invariant Momenta
Min-Quan Kuang, Hua-Yu Li
At non-time-reversal-invariant momenta (non-TRIMs), time-reversal symmetry does not constrain the linear term of the band dispersion. Whether vanishes is therefore deter…
Type-I and Type-II Saddle Points and a Topological Flat Band in a Bi-Pyrochlore Superconductor CsBi2
Yusei Morita, Yongkai Li, Yu-Hao Wei +12
The divergence of the electron density of states (DOS) plays an important role in enhancing many-body interactions and inducing various quantum phases in low-dimensional systems. H…
Directional Criticality and Higher-Order Flatness: Designing Van Hove Singularities in Three Dimensions
Hua-Yu Li, Hengxin Tan, Hao-Yu Zhu +2
Van Hove singularities (VHSs) play a pivotal role in driving correlated electronic phenomena. Traditional classifications focus only on critical points where the band gradient vani…
Two-dimensional phase diagram of the charge density wave in doped CsVSb
Linwei Huai, Hongyu Li, Yulei Han +15
Kagome superconductors AVSb (A = K, Rb and Cs) have attracted much recent attention due to the coexistence of multiple exotic orders. Among them, the charge density wave (C…
Tunable van Hove singularity without structural instability in Kagome metal CsTiBi
Bo Liu, Minquan Kuang, Yang Luo +12
In Kagome metal CsVSb, multiple intertwined orders are accompanied by both electronic and structural instabilities. These exotic orders have attracted much recent attention…
Coexistence of zero-, one- and two-dimensional degeneracy in tetragonal SnO phonons
Jianhua Wang, Hongkuan Yuan, Minquan Kuang +4
Based on the dimension of degeneracy, topological electronic systems can roughly be divided into three parts: nodal point, line and surface materials corresponding to zero-, one- a…
Perovskite-type YRhB with multiple types of nodal point and nodal line states
Feng Zhou, Chaoxi Cui, Jianhua Wang +6
Experimentally synthesized perovskite-type YRhB with a type structure was proposed as a novel topological material (TM) via first-principles calculations and the…
Coexistence of hourglass Weyl and Dirac nodal line phonons in orthorhombic-type KCuS
Jianhua Wang, Hongkuan Yuan, Ying Liu +6
In parallel to electronic systems, the concept of topology has been extended to phonons, which has led to the birth of topological phonons. Very recently, nodal point phonons, noda…
Symmetry-enforced ideal lantern-like phonons in ternary nitride LiWN
Xiaotian Wang, Feng Zhou, Tie Yang +3
Condensed matter systems contain both fermionic and bosonic quasiparticles. Owing to the constraint imposed by the Fermi level, ideal material candidate for the emergent particles…
Coexistience of phononic six-fold, four-fold and three-fold excitations in ternary antimonide Zr3Ni3Sb4
Mingmin Zhong, Ying Liu, Feng Zhou +4
Three-, four-, and six-fold excitations have significantly extended the subjects of condensed matter physics. There is an urgent need for a realistic material that can have coexist…
Intersecting topological nodal ring and nodal wall states in superhard superconductor FeB4
Feng Zhou, Ying Liu, Jianhua Wang +4
Novel materials with both topological nontrivial states and superconductivity have attracted considerable attention in recent years. Single-crystal FeB4 was recently synthesized an…
