Non-Hermitian theory is a theoretical framework used to describe open systems. It offers a
powerful tool in the characterization of both the intrinsic degrees of freedom of a system and …

Non-Hermitian matrices are ubiquitous in the description of nature ranging from classical
dissipative systems, including optical, electrical, and mechanical metamaterials, to scattering …

We propose a novel type of skin effects in non-Hermitian quantum many-body systems that
we dub a “non-Hermitian Mott skin effect.” This phenomenon is induced by the interplay …

Exceptional points (EPs) of non-Hermitian (NH) systems have recently attracted increasing
attention due to their rich phenomenology and intriguing applications. Compared to the …

We demonstrate the existence of topologically stable unpaired exceptional points (EPs), and
construct simple non-Hermitian (NH) tight-binding models exemplifying such remarkable …

The spectrum of a non-Hermitian system generically forms a two-dimensional complex
Riemannian manifold with a distinct topology from the underlying parameter space. This …

In non-Hermitian systems, defective band degeneracies called exceptional points can form
exceptional lines (ELs) in 3D momentum space in the absence of any symmetries. However …

Majorana zero modes (MZMs) emerge as edge states in topological superconductors and
are promising for topological quantum computation, but their detection has so far been …

Non-Hermiticity has emerged as a new paradigm for controlling coupled-mode systems in
ways that cannot be achieved with conventional techniques. One aspect of this control that …

Both non-Hermitian systems and the behavior of emitters coupled to structured baths have
been studied intensely in recent years. Here, we study the interplay of these paradigmatic …
