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.
Physical networks are systems composed of physical entities, which conventional graph-based approaches fail to capture. Theoretical work now introduces a meta-graph technique to uncover the impact of physicality on the structure of networks.
Network geometry is an emerging framework used to describe several topological and organizational features of complex networks. Now this approach has been extended to directed networks, which contain both symmetric and asymmetric interactions.
Cell division is governed by the positioning of a cytoskeletal structure called the spindle. Two methods, one based on laser ablation and the other on fluid flow assessments, are now shown to be useful tools for studying spindle positioning.
Non-Hermitian physics enables dynamic control of optical behaviour in real time, such as reflectionless scattering modes, which have now been demonstrated in a chaotic photonic microcavity.
Polarons are quasi-particles formed by impurities together with induced excitations in a surrounding medium. Now, mediated interactions between polarons have been detected using atomic impurities embedded in a Fermi gas of ultracold atoms.
A computational method capable of capturing the effects of electronic interactions and scattering can help interpret the vibrational reflectance measurements in superconducting and bad metals.
Despite the theoretical prediction of spinaron quasiparticles in artificial nanostructures, experimental evidence has not yet been seen. Now it has been observed in a hybrid system comprising Co atoms on a Cu(111) surface.
The phase transition from a topologically trivial state to non-Hermitian conducting edge modes can be controlled by optical nonlinearities, achieving picosecond switching speeds.
It is hoped that simulations of molecules and materials will provide a near-term application of quantum computers. A study of the performance of error mitigation highlights the obstacles to scaling up these calculations to practically useful sizes.
Resolving the structural changes of a deformed glass on the atomic scale is challenging due to its disordered nature. Now, high-energy diffraction measurements show that non-line-preserving atomic displacements in glasses correlate with structural anisotropy.
Filaments of the FtsZ protein can form chiral assemblies. Now, active matter tools link the microscopic structure of active filaments to the large-scale collective phase of these assemblies.
