Identifying Topological Invariants of Non-Hermitian Systems via Domain-Adaptive Multimodal Model for Mathematics
Jiuchun Meng, Lichao Sun, Xiumei Wang +2
Identifying topological invariants are endowed with profound physical connotations in the fields of condensed matter physics. However, they are often limited by the failure of stan…
Waveguiding in two-dimensional Floquet non-Abelian topological insulators
Yujie Zhou, Changsen Li, Xiumei Wang +1
Topological phases characterized by non-Abelian charges have garnered increasing attention recently. Although Floquet (periodic-driving) higher-order topological phases have been e…
Three-period evolution in a photonic Floquet extended Su-Schrieffer-Heeger waveguide array
Changsen Li, Yujie Zhou, Xiumei Wang +1
Periodic driving can induce the emergence of topological pi modes, and their superposition with zero modes leads to two-period dynamics. Introducing long-range couplings enables th…
Amortized Clustering Assistant Classification of Anomalous Hybrid Floquet Modes in a Periodically Driven non-Hermitian Lattice
Yifei Xia, Xiumei Wang, Yali Li +1
The interplay between Floquet periodically driving and non-Hermiticity could bring about intriguing novel phenomena with anomalous Floquet topological phases of a finite-size, tigh…
Low-Energy Boundary-State Emergence and Delocalization in Finite-sized Mosaic Wannier-Stark Lattices
Yi Kang, Zhenjia Yu, Xiumei Wang +1
The mosaic Wannier Stark lattice has gained increasing prominence as a disorder free system exhibiting unconventional localization behavior induced by spatially periodic Stark pote…
Self-Attention Assistant Classification of Non-Hermitian Phases in Two-Dimensional Lattice
Hengxuan Jiang, Xiumei Wang, Xingping Zhou
Classification of the non-Hermitian phases in high-dimensional lattice becomes challenging due to interplay of the band topology and non-Hermiticity. The significant increase in da…
