Faraday waves are standing waves on the surface of a vibrating liquid. Large-wavelength polygonal Faraday waves are now observed in concave water containers, the dynamics of which bear resemblance to Faraday waves seen in Bose–Einstein condensates.

Time-resolved measurements show that coupling between electrons and phonons in lead halide perovskites can mediate attractive interactions between excitons, although the interaction strength depends on the specific material.

Interactions between a localized magnetic moment and electrons in a metal can produce an emergent resonance that affects the metal’s properties. A realization of this Kondo effect in MoS₂ provides an opportunity to study it in microscopic detail.

A detailed analysis of inelastic neutron scattering data, including the evaluation of entanglement witnesses used in quantum information theory, supports the proposal that the triangular-lattice antiferromagnet KYbSe₂ is close to a spin-liquid phase.

Interactions between excitons and correlated electrons can lead to the formation of interesting states. Now, evidence suggests that these interactions can give rise to a Mott insulator of excitons.

The hectare has a long association with the metric system, but its most recent status has created some ambiguity as to its future application. Richard Brown surveys the lay of the land.

Invest in fostering a culture of collaboration to help break down barriers between disciplines.

Fluid flows play a key part in living systems. Cross-disciplinary engagement between fluid physics and biology greatly benefits both fields.

Multidisciplinary residential programmes and workshops help advance all the fields involved.

Creating a common culture and language for successful collaboration across disciplines benefits both researchers and scientific discovery.
