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.
Inauguration du centre de transfert de technologie Swiss PIC
Fondé conjointement par des scientifiques du PSI et par des partenaires de la recherche et de l’industrie, le Swiss Photonics Integration Center Swiss PIC a été solennellement inauguré le 24 novembre 2025.
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.
