Crystal symmetry predicts unconventional magnetism
Ziyin Song, Zhong Fang, Chen Fang +1
Unconventional compensated magnets combine zero net magnetization with momentum-dependent spin polarization, but identifying them usually requires knowledge of their magnetic order…
A Unified Symmetry Classification of Magnetic Orders via Spin Space Groups: Prediction of Coplanar Even-Wave Phases
Ziyin Song, Ziyue Qi, Chen Fang +2
Spin space groups (SSGs) impose fundamentally different constraints on magnetic configurations in real and reciprocal spaces. As a consequence, the correspondence between real-spac…
IRSSG: An Open-Source Software Package for Spin Space Groups
Sheng Zhang, Ziyin Song, Zhong Fang +2
We present an open-source software package IRSSG for investigating magnetic systems with spin space groups (SSGs). The package works within the density functional theory (DFT) fram…
Axion insulator, Weyl points, quantum anomalous Hall effect and magnetic topological phase transition in Eu3In2As4
Jingyu Yao, Ruihan Zhang, Sheng Zhang +5
The magnetic topological phases attract much interest, such as the axion insulator, higher-order topology, Weyl semimetals, and the quantum anomalous Hall effect (QAHE). Here, we p…
Constructions and Applications of Irreducible Representations of Spin-Space Groups
Ziyin Song, A. Z. Yang, Yi Jiang +5
Spin-space groups (SSGs), including the traditional space groups (SGs) and magnetic space groups (MSGs) as subsets, describe the complete symmetries of magnetic materials with weak…
VASP2KP: kp models and Lande g-factors from ab initio calculations
Sheng Zhang, Haohao Sheng, Zhi-Da Song +8
The method is significant in condensed matter physics for the compact and analytical Hamiltonian. In the presence of magnetic field, it is described by the effective Zee…
Magnetically driven loss of centrosymmetry in metallic Pb2CoOsO6
A. J. Princep, H. L. Feng, Y. F. Guo +11
We report magnetic, transport, neutron diffraction, and muon spin rotation data showing that PbCoOsO, a newly synthesized metallic double-perovskite with a centrosymmetric…
Two-dimensional spin-valley-coupled Dirac semimetals in functionalized SbAs monolayers
Zhifeng Liu, Wangxiang Feng, Hongli Xin +5
In the presence of spin-orbit coupling (SOC), achieving both spin and valley polarized Dirac state is significant to promote the fantastic integration of Dirac physics, spintronics…
Three-component fermions with surface Fermi arcs in topological semimetal tungsten carbide
J. -Z. Ma, J. -B. He, Y. -F. Xu +19
Topological Dirac and Weyl semimetals not only host quasiparticles analogous to the elementary fermionic particles in high-energy physics, but also have nontrivial band topology ma…
Experimental Observation of Three-Component 'New Fermions' in Topological Semimetal MoP
B. Q. Lv, Z. -L. Feng, Q. -N. Xu +10
Condensed matter systems can host quasiparticle excitations that are analogues to elementary particles such as Majorana, Weyl, and Dirac fermions. Recent advances in band theory ha…
Compensated semimetal LaSb with unsaturated magnetoresistance
L. -K. Zeng, R. Lou, D. -S. Wu +23
By combining angle-resolved photoemission spectroscopy and quantum oscillation measurements, we performed a comprehensive investigation on the electronic structure of LaSb, which e…
