  • The mechanism of the multiple-q charge density wave phase in the antiferromagnetic kagome metal FeGe is not fully understood. Here the authors reveal dimerization-driven hexagonal charge-diffuse precursor and identify the fraction of dimerized/undimerized states as the key order parameter of the phase transition.

  • We establish a spin nematic phase in the square-lattice iridate Sr2IrO4 and find a complete breakdown of coherent magnon excitations at short-wavelength scales, suggesting a many-body quantum entanglement in the antiferromagnetic state.

  • The anomalous Hall effect (AHE) occurs in ferromagnets caused by intrinsic and extrinsic mechanisms. Here, Yoo et al. report large anomalous Hall conductivity and Hall angle at the interface between a ferromagnet La0.7Sr0.3MnO3 and a semimetallic SrIrO3, due to the interplay between correlated physics and topological phenomena.

  • The recently discovered charge density wave in ScV6Sn6 kagome metal is under intense debate. By using a combination of experimental and theoretical techniques, the authors point to the role of flat phonon mode softening and momentum-dependent electron-phonon coupling in the formation of the charge density wave.

  • Analysing the structure of a PbTiO3 epitaxial layer sandwiched between SrRuO3 electrodes led to observation of a topology with two periodic modulations that form an incommensurate polar crystal, providing an analogue to incommensurate spin crystals.
