Two-orbital model for possible superconductivity pairing mechanism in nickelates
Chen Lu, Lun-Hui Hu, Yu Wang +2
The newly synthesized strontium doped RNiO (R=Nd, La) superconductors have stimulated extensive interests in understanding their pairing mechanism and pairing nature. Here we s…
Crossover of Ising- to Rashba-Type Superconductivity in Epitaxial Bi2Se3/Monolayer NbSe2 Heterostructures
Hemian Yi, Lun-Hui Hu, Yuanxi Wang +15
A topological insulator (TI) interfaced with an s-wave superconductor has been predicted to host an unusual form of superconductivity known as topological superconductivity (TSC).…
Competing Vortex Topologies in Iron-based Superconductors
Lun-Hui Hu, Xianxin Wu, Chao-Xing Liu +1
In this work, we establish a new theoretical paradigm for vortex Majorana physics in the recently discovered topological iron-based superconductors (tFeSCs). While tFeSCs are widel…
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…
Quasi-symmetry protected topology in a semi-metal
Chunyu Guo, Lunhui Hu, Carsten Putzke +10
The crystal symmetry of a material dictates the type of topological band structures it may host, and therefore symmetry is the guiding principle to find topological materials. Here…
Observation of Superconductivity Induced Ferromagnetism in an Fe-Chalcogenide Superconductor
Nathan J. McLaughlin, Hailong Wang, Mengqi Huang +8
The interplay among topology, superconductivity, and magnetism promises to bring a plethora of exotic and unintuitive behaviors in emergent quantum materials. The family of Fe-chal…
Phonon helicity induced by electronic Berry curvature in Dirac materials
Lun-Hui Hu, Jiabin Yu, Ion Garate +1
In two-dimensional insulators with time-reversal (TR) symmetry, a nonzero local Berry curvature of low-energy massive Dirac fermions can give rise to nontrivial spin and charge res…
High-order Time-Reversal Symmetry Breaking Normal State
Meng Zeng, Lun-Hui Hu, Hong-Ye Hu +2
Spontaneous time-reversal symmetry breaking plays an important role in studying strongly correlated unconventional superconductors. When two superconducting gap functions with diff…
Spontaneous magnetization in unitary superconductors with time reversal symmetry breaking
Lun-Hui Hu, Xuepeng Wang, T. Shang
We report the study of spontaneous magnetization (i.e., spin-polarization) for time-reversal symmetry (TRS)-breaking superconductors with unitary pairing potentials, in the absence…
Topological excitonic corner states and nodal phase in bilayer quantum spin Hall insulators
Zheng-Rong Liu, Lun-Hui Hu, Chui-Zhen Chen +2
Interaction induced topological states remain one of the fascinating phases in condensed matter physics. The exciton condensate has recently sparked renewed interest due to the dis…
