A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …

The emergent field of cavity quantum materials bridges collective many-body phenomena in
solid state platforms with strong light–matter coupling in cavity quantum electrodynamics …

An ensemble of emitters can behave very differently from its individual constituents when
they interact coherently via a common light field. After excitation of such an ensemble …

Insights from spectroscopic experiments led to the development of quantum mechanics as
the common theoretical framework for describing the physical and chemical properties of …

Dicke superradiance is an example of emergence of macroscopic quantum coherence via
correlated dissipation. Starting from an initially incoherent state, a collection of excited atoms …

The permutational invariance of identical two-level systems allows for an exponential
reduction in the computational resources required to study the Lindblad dynamics of …

Strong coupling and the resultant mixing of light and matter states is an important asset for
future quantum technologies. We demonstrate deterministic room temperature strong …

This report on progress explores recent advances in our theoretical and experimental
understanding of the physics of open quantum systems (OQSs). The study of such systems …

Enhancing the optical cross section is an enticing goal in light-matter interactions, due to its
fundamental role in quantum and nonlinear optics. Here, we show how dipolar interactions …

Self‐assembly of nanoscale building blocks into ordered nanoarchitectures has emerged as
a simple and powerful approach for tailoring the nanoscale properties and the opportunities …
