An important goal of modern condensed-matter physics involves the search for states of
matter with emergent properties and desirable functionalities. Although the tools for material …

Polariton lasers emit coherent monochromatic light through a spontaneous emission
process. As a rare example of a system in which Bose–Einstein condensation and …

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 …

Rapidly growing demands for fast information processing have launched a race for creating
compact and highly efficient optical devices that can reliably transmit signals without losses …

Abstract The study of Bose–Einstein condensation effects in photonic systems has revealed
a rich phenomenology related to spontaneous coherence generation in driven-dissipative …

Topological insulators—materials that are insulating in the bulk but allow electrons to flow
on their surface—are striking examples of materials in which topological invariants are …

Controlling matter–light interactions with cavities is of fundamental importance in modern
science and technology 1. This is exemplified in the strong-coupling regime, where matter …

Revealing universal behaviours is a hallmark of statistical physics. Phenomena such as the
stochastic growth of crystalline surfaces and of interfaces in bacterial colonies, and spin …

Abstract 2D and 3D solitons and related states, such as quantum droplets, can appear in
optical systems, atomic Bose–Einstein condensates (BECs) and liquid crystals, among other …

Structured waves are ubiquitous for all areas of wave physics, both classical and quantum,
where the wavefields are inhomogeneous and cannot be approximated by a single plane …
