Floquet spin-group theory for light-tailored spin splitting in collinear magnets
Tongshuai Zhu, Zixuan Li, Huaiqiang Wang +2
Spin groups have emerged as a fundamental symmetry framework for spin-splitting antiferromagnets, including altermagnets. For periodically driven magnets, where new spin-splitting…
Floquet odd-parity collinear magnets
Tongshuai Zhu, Di Zhou, Huaiqiang Wang +2
Altermagnets (AMs), recently discovered unconventional magnets distinct from both ferro- and antiferromagnets, have rapidly emerged as a prominent research topic in condensed matte…
Optically controlled single-valley exciton doublet states with tunable internal spin structures and spin magnetization generation
Jiawei Ruan, Zhenglu Li, Chin Shen Ong +1
Manipulating quantum states through light-matter interactions has been actively pursued in two-dimensional (2D) materials research. Significant progress has been made towards the o…
Dynamical axion state with hidden pseudospin Chern numbers in MnBiTe-based heterostructures
Huaiqiang Wang, Dinghui Wang, Zhilong Yang +5
Axion is a hypothetical elementary particle which was initially postulated to solve the charge conjugation-parity problem in particle physics. Interestingly, the axion state has em…
Non-Hermitian nodal-line semimetals with an anomalous bulk-boundary correspondence
Huaiqiang Wang, Jiawei Ruan, Haijun Zhang
Recently, topological quantum states of non-Hermitian systems, exhibiting rich new exotic states, have attracted great attention in condensed-matter physics. As for the demonstrati…
Engineering topological phases in the Luttinger semimetal -Sn
Dongqin Zhang, Huaiqiang Wang, Jiawei Ruan +2
-Sn is well known as a typical Luttinger semimetal with a quadratic band touching at the point. Based on the effective analysis as well as first-principles calcul…
XXZ-Ising model on the triangular kagome lattice with spin-1 on the decorated trimers
Chengkang Zhou, Yuanwei Feng, Jiawei Ruan +1
We consider the triangular kagome XXZ-Ising model (TKL XXZ-Ising model) formed by inserting small triangles ("a-trimers") with XXZ spin-1 inside the triangles of the kagome lattice…
Strain-induced quantum topological phase transitions in Na3Bi
Dexi Shao, Jiawei Ruan, Juefei Wu +6
Strain can be used as an effective tool to tune the crystal structure of materials and hence to modify their electronic structures, including topological properties. Here, taking N…
Ideal Weyl semimetals in the chalcopyrites CuTlSe2, AgTlTe2, AuTlTe2 and ZnPbAs2
Jiawei Ruan, Shao-Kai Jian, Dongqin Zhang +4
Weyl semimetals are new states of matter which feature novel Fermi arcs and exotic transport phenomena. Based on first-principles calculations, we report that the chalcopyrites CuT…
Symmetry-protected ideal Weyl semimetal in HgTe-class materials
Jiawei Ruan, Shao-Kai Jian, Hong Yao +3
Ideal Weyl semimetals with all Weyl nodes exactly at the Fermi level and no coexisting trivial Fermi surfaces in the bulk, similar to graphene, could feature deep physics such as e…
