Non-Hermitian band structures have gained considerable attention due to the novel
phenomena not present in their Hermitian counterparts and their connection to various …

Exceptional points are complex branching singularities of non-Hermitian bands that have
lately attracted considerable interest, particularly in non-Hermitian photonics. In this article …

Quantum Hall systems host chiral edge states extending along the one-dimensional
boundary of any two-dimensional sample. In solid state materials, the edge states serve as …

The non-Bloch band theory can describe energy bands in a one-dimensional (1D) non-
Hermitian system. On the other hand, whether the non-Bloch band theory can be extended …

Mode-locked lasers play a crucial role in modern science and technology. They are
essential to the study of ultrafast and nonlinear optics, and they have applications in …

The 2 μm wavelength belongs to the eye-safe band and has a wide range of applications in
the fields of lidar, biomedicine, and materials processing. With the rapid development of …

A bstract We discuss minimally supersymmetric AdS 3 flux vacua of massive type IIA
supergravity on G2-orientifolds. We find that configurations with broken scale-separation can …

Recent years have witnessed a flurry of research activities in topological photonics,
predominantly driven by the prospect for topological protection–a property that endows such …

The non-Hermitian skin effect (NHSE), which involves an extensive number of bulk modes
collapsing to open boundaries as skin modes, unveils a variety of unprecedented …

Non-Hermitian skin effect (NHSE) is an intrinsic non-Hermitian phenomenon where an
extensive number of eigenmodes, called skin modes, are localized at the boundary of a …
