Simulating Floquet non-Abelian topological insulator with photonic quantum walks
Quan Lin, Tianyu Li, Haiping Hu +2
Floquet non-Abelian topological phases emerge in periodically driven systems and exhibit properties that are absent in their Abelian or static counterparts. Dubbed the Floquet non-…
Spreading dynamics in the Hatano-Nelson model with disorder
Jinyuan Shang, Haiping Hu
The non-Hermitian skin effect is the accumulation of eigenstates at the boundaries, reflecting the system's nonreciprocity. Introducing disorder leads to a competition between the…
Dissipation-assisted preparation of topological boundary states
Yi Peng, Chao Yang, Haiping Hu +1
Robust states emerging at the boundaries of a system are an important hallmark of topological matter. Here, using the Su-Schrieffer-Heeger model and the Kitaev chain as examples, w…
Universal Spreading Dynamics in Quasiperiodic Non-Hermitian Systems
Ze-Yu Xing, Shu Chen, Haiping Hu
Non-Hermitian systems exhibit a distinctive type of wave propagation, due to the intricate interplay of non-Hermiticity and disorder. Here, we investigate the spreading dynamics in…
Non-Hermitian skin effect in arbitrary dimensions: non-Bloch band theory and classification
Yuncheng Xiong, Ze-Yu Xing, Haiping Hu
Non-Hermitian skin effect (NHSE) is a distinctive phenomenon in non-Hermitian systems, characterized by a significant accumulation of eigenstates at system boundaries. While well-u…
Floquet Non-Abelian Topological Insulator and Multifold Bulk-Edge Correspondence
Tianyu Li, Haiping Hu
Topological phases characterized by non-Abelian charges are beyond the scope of the paradigmatic tenfold way and have gained increasing attention recently. Here we investigate topo…
