The past few years have witnessed a surge of interest in non-Hermitian Floquet topological
matter due to its exotic properties resulting from the interplay between driving fields and non …

The synergy between non-Hermitian concepts and topological ideas have led to very fruitful
activity in the recent years. Their interplay has resulted in a wide variety of new non …

Recent years have seen remarkable development in open quantum systems effectively
described by non-Hermitian Hamiltonians. A unique feature of non-Hermitian topological …

We develop a theory of symmetry in open quantum systems. Using the operator-state
map**, we characterize symmetry of Liouvillian superoperators for the open quantum …

Lately, the non-Hermitian skin effect (NHSE) has been demonstrated in various classical
metamaterials and even ultracold atomic arrays. Yet, its interplay with many-body dynamics …

By analyzing the Lyapunov exponent (LE), we develop a rigorous, fundamental scheme for
the study of general non-Hermitian quasicrystals with both a complex phase factor and …

Dimensionality plays a fundamental role in the classification of novel phases and their
responses. In generic lattices of 2D and beyond, however, we found that non-Hermitian …

The spectral statistics of non-Hermitian random matrices are of importance as a diagnostic
tool for chaotic behavior in open quantum systems. Here, we investigate the statistical …

Strong local disorder in interacting quantum spin chains can turn delocalized eigenmodes
into localized eigenstates, giving rise to many-body localized phases. This is accompanied …

The interplay between non-Hermiticity and disorder plays an important role in condensed
matter physics. Here, we report the universal critical behaviors of the Anderson transitions …
