When molecules are coupled to an optical cavity, new light–matter hybrid states, so-called
polaritons, are formed due to quantum light–matter interactions. With the experimental …

In this review, we present the theoretical foundations and first-principles frameworks to
describe quantum matter within quantum electrodynamics (QED) in the low-energy regime …

Interactions between light and matter play an instrumental role in spectroscopy, sensing,
quantum information processing and lasers. In most of these applications, light is considered …

This is a tutorial-style introduction to the field of molecular polaritons. We describe the basic
physical principles and consequences of strong light–matter coupling common to molecular …

The study of topology as it relates to physical systems has rapidly accelerated during the
past decade. Critical to the realization of new topological phases is an understanding of the …

Axions are hypothetical particles that were proposed to solve the strong charge–parity
problem in high-energy physics. Although they have long been known in quantum field …

Discoveries in quantum materials, which are characterized by the strongly quantum-
mechanical nature of electrons and atoms, have revealed exotic properties that arise from …

Experiments at the interface of quantum optics and chemistry have revealed that strong
coupling between light and matter can substantially modify the chemical and physical …

The field of two-dimensional (2D) materials-based nanophotonics has been growing at a
rapid pace, triggered by the ability to design nanophotonic systems with in situ control …

The use of nanoplasmonics to control light and heat close to the thermodynamic limit
enables exciting opportunities in the field of plasmonic catalysis. The decay of plasmonic …
