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…
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…
Chiral Superconductivity in Periodically Driven Altermagnet/Superconductor Heterostructures
Xiaolin Wan, Zheng Qin, Fangyang Zhan +3
The interplay between magnetism and superconductivity provides a fertile ground for engineering exotic topological phases, while dynamical control via periodic driving offers a uni…
The spin Hall conductivity in the hole-doped bilayer Haldane-Hubbard model with odd-parity ALM
Minghuan Zeng, Ling Qin, Shiping Feng +2
Spin current generated electrically is among the core phenomena of spintronics for driving high-performance spin device applications. Here, on the basis of systematic investigation…
Spontaneously broken chiral symmetry in the interacting Kane-Mele model
Minghuan Zeng, Junjie Zeng, Ling Qin +3
The essential properties of the half-filled interacting Kane-Mele model on a hexagon lattice is studied using the slave rotor approach. It is shown clearly that a long-range charge…
