  • Neutron and X-ray scattering measurements provide further insight into the anharmonic behaviour of lead halide perovskites, revealing that rotations of PbBr6 octahedra in CsPbBr3 crystals occur in a correlated fashion along two-dimensional planes.

  • 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.

  • Spin liquids are predicted to emerge in materials that combine strong electronic correlations with geometric frustration. Evidence has now been found for a spin liquid state in the triangular-lattice material NaRuO2.

  • Thermoelectric efficiency of SnS and SnSe is reported to peak around the phase transition temperature around 800 K; however, the transition mechanism and origin of ultralow thermal conductivity remain unclear. Here, the authors reveal the soft-mode mechanism of the phase transition that impacts thermal transport and thermoelectric efficiency.

  • The honeycomb lattice is of fundamental importance for understanding quantum spin liquids and frustrated magnetism more generally. Here, the authors use inelastic neutron scattering to investigate the honeycomb antiferromagnet YbCl3 showing how quantum effects renormalize the single-magnon and multimagnon excitations, shedding further light on the mechanisms of quantum magnetism in honeycomb-lattice compounds.
