The odd-parity altermagnetism induced reconstruction of the Chern-insulating phase in Haldane-Hubbard model

Minghuan Zeng, Zheng Qin, Ling Qin +4

Odd-parity altermagnetism(ALM) extends compensated collinear magnetism beyond the even-parity spin splitting of conventional altermagnets, but its role in correlated topological ph…

Spin-orbit-enabled Fermi-surface splitting in noncollinear antiferromagnetic SmBi

Long Zhang, Ming Cheng, Jingyu Li +10

Spin-split electronic structures in compensated antiferromagnets are commonly sought in the nonrelativistic limit, where magnetic order lifts spin degeneracy without spin-orbit cou…

Hybrid-order topology in two-dimensional nonsymmorphic antiferromagnets

Wei Xiong, Zi-Ming Wang, Xin-Mei Wei +2

We theoretically demonstrate hybrid-order topology in a two-dimensional nonsymmorphic antiferromagnet. Utilizing a generic antiferromagnetic Dirac model with a symmetry-allowed, mo…

Floquet second-order topological insulator in strained graphene

Yu-Wen Xu, Xiaolin Wan, Zi-Ming Wang +2

Graphene provides a canonical setting for Floquet band engineering, where circularly polarized light can dynamically open topological gaps at Dirac points and generate nonequilibri…

Engineering Helical Superconductors with Multiple Majorana Kramers Pairs via Higher-Order Rashba Spin-Orbit Coupling

Qi-Sheng Xu, Zi-Ming Wang, Chui-Zhen Chen +3

The momentum dependence of Rashba spin-orbit coupling (RSOC) is a key ingredient for engineering topological superconductors (TSCs), yet research has overwhelmingly focused on its…
