Many-Body Non-Hermitian Physics in the Generalized Brillouin Zone
Chaoze Lu, Chuanshu Xu, Zhenghao Yang +1
The breakdown of conventional bulk-boundary correspondence (BBC) in non-Hermitian system can be resolved by the generalized Brillouin zone (GBZ) theory. However, extending the GBZ…
Spin Splitting Nernst Effect in Altermagnet
Xing-Jian Yi, Yue Mao, Xiancong Lu +1
Altermagnet is a distinctive magnet phase, which has spin-split energy band but with zero net magnetic moment. In this paper, we propose that altermagnet behaves spin splitting Ner…
Third-order Orbital Corner State and its Realization in Acoustic Crystals
Jiyu Wang, Ying Chen, Xiancong Lu
Three dimensional (3D) third-order topological insulators (TIs) have zero-dimensional (0D) corner states, which are three dimensions lower than bulk. Here we investigate the third-…
Entangelment Entropy on Generalized Brillouin Zone
Zhenghao Yang, Chaoze Lu, Xiancong Lu
We investigate the entanglement properties of non-Hermitian Su-Schrieffer-Heeger (SSH) model from the perspective of the Generalized Brillouin Zone (GBZ). The non-Bloch entanglemen…
Topological phases in twisted Rashba superconductors
Conghao Lin, Xiancong Lu
We study the topological properties of a twisted superconducting bilayer with spin-singlet pairings and Rashba spin-orbital coupling. By introducing the chirality basis, we obtain…
