This article reviews recent developments in the non-Hermitian skin effect (NHSE),
particularly on its rich interplay with topology. The review starts off with a pedagogical …

Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

We propose a realistic cold-atom quantum setting where topological localization induces
nonreciprocal pum**. This is an intriguing non-Hermitian phenomenon that illustrates how …

Knots have a twisted history in quantum physics. They were abandoned as failed models of
atoms. Only much later was the connection between knot invariants and Wilson loops in …

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 …

We study a new class of non-Hermitian topological phases in three dimensions in the
absence of any symmetry, where the topological robust band degeneracies are Hopf-link …

Yang-Lee edge singularities (YLES) are the edges of the partition function zeros of an
interacting spin model in the space of complex control parameters. They play an important …

Within the expanding field of non-Hermitian physics, non-Hermitian pum** has emerged
as a key phenomenon, epitomized through the skin effect via extensive boundary mode …

Topological nodal line semimetals host stable chained, linked, or knotted line degeneracies
in momentum space protected by symmetries. In this Letter, we use the Jones polynomial as …

We review recent work on low-frequency Floquet engineering and its application to quantum
materials driven by light, focusing on van der Waals systems hosting Moiré superlattices …
