Non-Hermitian higher-order topological insulators enabled by altermagnet engineering
Xiang Ji, Dengfeng Wang, Tong Zhou +1
We show that proximity to an altermagnet provides an efficient route to engineering non-Hermitian higher-order topological phases. The proximity-induced altermagnetic order gaps th…
Floquet engineering of point-gapped topological superconductors
Xiang Ji, Hao Geng, Naeem Akhtar +1
Non-Hermitian systems exhibit two distinct topological classifications based on their gap structure: line-gap and point-gap topologies. Although point-gap topology is intrinsic to…
Generalized bulk-boundary correspondence in periodically driven non-Hermitian systems
Xiang Ji, Xiaosen Yang
We present a pedagogical review of the periodically driven non-Hermitian systems, particularly on the rich interplay between the non-Hermitian skin effect and the topology. We star…
Non-Hermitian second-order topological superconductors
Xaing Ji, Wenchen Ding, Yuanping Chen +1
The topology of non-Hermitian systems is fundamentally changed by the non-Hermitian skin effect, which leads to the generalized bulk-boundary correspondence. Based on the non-Bloch…
