Point-gap topology in amorphous non-Hermitian quantum systems
Xue-Min Yang, Mu Zhou, Deng-Feng Li +7
Recent studies have revealed that not only does the correspondence between spectral winding numbers and skin modes break down in non-Hermitian systems, but the energy spectrum itse…
Non-Hermitian second-order topological insulator with point gap
Xue-Min Yang, Hao Lin, Jian Li +3
The zero-mode corner states in the gap of two-dimensional non-Hermitian Su-Schrieffer-Heeger model are robust to infinitesimal perturbations that preserve chiral symmetry. However,…
Floquet composite Dirac semimetals
Hong Wu, Jia-Ji Zhu, Jian Li +3
Dirac semimetals can be classified into types I, II, and III based on the topological charge of their Dirac points. If a three-dimensional (3D) system can be sliced into a family o…
RKKY interaction in helical higher-order topological insulators
Sha Jin, Jian Li, Qing-Xu Li +1
We theoretically investigate the RKKY interaction in helical higher-order topological insulators (HOTIs), revealing distinct behaviors mediated by hinge and Dirac-type bulk carrier…
Tunable non-Hermitian skin effect via gain and loss
Wen-Cheng Jiang, Hong Wu, Jian Li +2
We investigate theoretically tunable non-Hermitian skin effect in systems with gain and loss, and find that bipolar (quadripolar) non-Hermitian skin effect characterized by topolog…
The electronic structure of intrinsic magnetic topological insulator MnBi2Te4 quantum wires
Jian Li, Zhu-Cai Yin, Qing-Xv Li +1
The ferromagnetic and antiferromagnetic nanostructure are crucial for fundamental spintronics devices, motivated by its potential application in spintronics, we theoretically inves…
Self-supervised graph neural networks for accurate prediction of Néel temperature
Jian-Gang Kong, Qing-Xu Li, Jian Li +2
Antiferromagnetic materials are exciting quantum materials with rich physics and great potential for applications. It is highly demanded of the accurate and efficient theoretical m…
