Chiral phonons in polar LiNbO3
Resonant inelastic x-ray scattering reveals that lattice vibrations can be chiral in a polar material, with phonons having opposite handedness depending on their direction in momentum space.

Unravelling the coexistence of insulating and metallic-like excitations in SrIrO₃
A team led by researchers from the Paul Scherrer Institute PSI used resonant inelastic X-ray scattering to probe spin and charge fluctuations in atomically engineered SrIrO₃. The results revealed that insulator-like and metallic-like modes can simultaneously emerge in a correlated 5d semimetal, advancing the understanding of “strange metal” behaviour in spin–orbit coupled systems.
