    The past decade has witnessed remarkable progress in our understanding of equilibration, thermalization and prethermalization, due in large part to experimental breakthroughs in ultracold atomic gases. This Review discusses theoretical and experimental advances on these topics and the challenges ahead.

    The charge radius of the proton is controversial because measurements by different methods disagree. Recent results indicate that these measurements might be reconciled. In this Review, we discuss the experimental techniques used to measure the proton radius and describe the current status of the field as well as forthcoming experiments.

    Axion fields provide a unique way to understand large quantized electromagnetic responses in topological insulators and dynamics in Weyl semimetals. This Review discusses the theory of axion fields in condensed matter, their experimental realization and their application in next-generation devices.

    Holographic duality is an equivalence relation between a gravitational system and a quantum many-body system. The Review discusses various insights obtained from the duality into properties of strongly coupled matter, quantum many-body chaos and deep connections between quantum information and geometry.

    The coupling of photons to material quasiparticles such as plasmons, phonons and excitons opens new possibilities in light–matter interactions. This Review presents a generalized view of such quasiparticles and the technique that describes their interactions with matter: macroscopic quantum electrodynamics.
