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…
Spin-Orbital Altermagnetism
Zi-Ming Wang, Yang Zhang, Song-Bo Zhang +4
Altermagnet is a newly discovered magnetic phase, characterized by non-relativistic spin-splitting that has been experimentally observed. Here, we introduce a framework dubbed {\it…
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…
Theory of Second-Order Topological Superconductors
Zi-Ming Wang, Meng Zeng, Chen Lu +4
Topological superconductors are a class of unconventional superconducting materials featuring sub-gap zero-energy Majorana bound modes that hold promise as a building block for top…
Floquet Weyl semimetal phases in light-irradiated higher-order topological Dirac semimetals
Zi-Ming Wang, Rui Wang, Jin-Hua Sun +2
Floquet engineering, the concept of tailoring a system by a periodic drive, is increasingly exploited to design and manipulate topological phases of matter. In this work, we study…
Spin-orbit-coupled superconductivity with spin-singlet non-unitary pairing
Meng Zeng, Dong-Hui Xu, Zi-Ming Wang +1
An unconventional superconductor is distinguished with two types of gap functions: unitary and non-unitary. This core subject has been concentrated on purely spin-triplet or single…
Pseudospin-Triplet Pairing in Iron-Chalcogenide Superconductors
Meng Zeng, Dong-Hui Xu, Zi-Ming Wang +2
We study superconductivity of electron systems with both spin and pseudospin-1/2 degrees of freedom. By solving linearized gap equations, we derive a weak coupling criterion for th…
