10 years on from the discovery of the quantum anomalous Hall effect, Yoshinori Tokura discusses the new physics it has opened up.

A paper in Nature Physics reports on freezing droplets that expel themselves from a textured surface.

A paper in Physical Review Letters reports on droplets that crumple or wrinkle as they dry, depending on whether they are above or below a substrate.

A paper in Journal of Fluid Mechanics presents a detailed characterization of what happens when two droplets hit a solid surface simultaneously — a situation that is relatively little-studied.

A paper in Physical Review Fluids shows that the early stages of growth of a bubble blown with gas from a reservoir can show an unexpected dependence on the reservoir’s initial volume.

A paper in Physical Review Applied reports on how the ink composition evolves over time in an inkjet printhead nozzle that is left idle.

A paper in Physics of Fluids reports on bubbles collapsing near a thin cylindrical fibre, which generate unusual planar jets.

This is the ‘behind the paper’ story of a 1953 article that established the use of Monte Carlo methods in physics.

75 years ago Richard Feynman developed a new approach to non-relativistic quantum mechanics: the path integral formulation.

Two recent experiments push the limits of nonlocality using massive particles and mesoscopic systems.

A paper in Physical Review Letters measures the spatial confinement of chiral edge modes and presents a model to show how it varies depending on disorder.

A paper in Nature Physics directly measures quantized conductance arising from the bulk states of a topological insulator.

A paper in Nano Letters uses optical excitations to probe the ultrafast carrier dynamics of magnetic topological insulator heterostructures.
