Hyperspin Altermagnets
Hai-Yang Ma, Yuanchang Li, Hu Xu +2
The behavior of spin quantum in k-space is key to identifying altermagnets (AMs) as the third kind of fundamental collinear magnetism. In contrast, non-collinear magnets,though abu…
Multicolor groups for molecules and solids
Hai-Yang Ma, Shihao Zhang, Hu Xu +2
The local magnetic moments of atoms in a molecule or solid can be designated by different colors. Magnetic groups, or 2-color groups, or black-and-white groups have been applied in…
Intrinsic second-order topological insulators in two-dimensional polymorphic graphyne with sublattice approximation
Z. J. Chen, S. G. Xu, Z. J. Xie +2
In two dimensions, intrinsic second-order topological insulators (SOTIs) are characterized by topological corner states that emerge at the intersections of distinct edges with reve…
Triple hourglass Weyl phonons
Guang Liu, Zhongjia Chen, Peng Wu +1
Unconventional Weyl phonons with higher topological charges in crystalline solids have attracted increasing attention. By symmetry analysis and low-energy effective Hamiltoni…
Three-dimensional Dirac Phonons with Inversion Symmetry
Zhongjia Chen, Rui Wang, Bowen Xia +4
Dirac semimetals associated with bulk Dirac fermions are well-known in topological electronic systems. In sharp contrast, three-dimensional (3D) Dirac phonons in crystalline solids…
Rational design principles of quantum anomalous Hall effect from superlattice-like magnetic topological insulators
Hongyi Sun, Bowen Xia, Zhongjia Chen +7
As one of paradigmatic phenomena in condensed matter physics, the quantum anomalous Hall effect (QAHE) in stoichiometric Chern insulators has drawn great interest for years. By usi…
Large Band Gap Quantum Anomalous Hall Phase in Hexagonal Organometallic Frameworks
Yuanjun Jin, Zhongjia Chen, Bowen Xia +3
The nontrivial band gap plays a critical role in quantum anomalous Hall (QAH) insulators. In this work, we propose that the intrinsic QAH phase with sizable band gaps up to 367 meV…
Topological Weyl and Node-Line Semimetals in Ferromagnetic Vanadium-Phosphorous-Oxide -VOPO Compound
Y. J. Jin, R. Wang, J. Z. Zhao +3
We propose that the topological semimetal features can co-exist with ferromagnetic ground state in vanadium-phosphorous-oxide -VOPO compound from first-principles calcul…
Strongly Ideal Robust Weyl Semimetals in Cubic Symmetry with Spatial-Inversion Breaking
R. Wang, J. Z. Zhao, Y. J. Jin +5
We show that compounds in a family that possess time-reversal symmetry and share a non-centrosymmetric cubic structure with the space group F-43m (No. 216) host robust ideal Weyl s…
