Evidence for chiral graviton modes in fractional quantum Hall liquids

Nature, Published online: 27 March 2024; doi:10.1038/s41586-024-07201-wThrough inelastic light scattering chiral spin-2 long-wavelength magnetorotons are observed, revealing chiral graviton modes in fractional quantum Hall states and aiding in understanding the quantum metric impacts in topological correlated systems.
