  • The authors demonstrate the existence of chiral phonons in a non-chiral ferroelectric material, opening the possibility for phonon chirality control through ferroic switching of the electric polarization.

  • Our experimental proof of chiral phonons demonstrates a degree of freedom in condensed matter that is of fundamental importance and opens the door to exploration of emergent phenomena based on chiral bosons.

  • In flat band materials, the ’flat’ dispersion of the electronic states mean that interactions between electrons can be strong, potentially leading to a variety of interesting magnetic and transport properties. Here, Nag et al study the Kagomé semimetal Co3Sn2S2, and show a nearly flat Stoner excitation dispersion, a clear indication of spin-polarized and flat electronic bands.

  • Here, Pelliciari et al. present resonant inelastic X-ray scattering on monolayer samples of unconventional superconductor FeSe, finding evidence for gapped and dispersionless spin excitations. These experiments are very difficult due to the extremely small scattering volume of the FeSe monolayer.

  • The authors present evidence for the formation of commensurate charge order in non-superconducting thin films of infinite-layer nickelates, whereas they find no charge order in a superconducting film.
