Delocalization of higher-order topological states in higher-dimensional non-Hermitian quasicrystals
A Shi, Y Peng, P Peng, J Chen, J Liu - Physical Review B, 2024 - APS
The combination of the non-Hermitian skin effect (NHSE) and topological effects plays a
crucial role in both fundamental and applied physics. Here, we show the interplay between …

Non-Hermitian quantum fractals
The first quantum fractal discovered in physics is the Hofstadter butterfly. It stems from large
external magnetic fields. We discover instead a class of non-Hermitian quantum fractals …
