The 11th International Conference on Superconductivity and Magnetism (ICSM 2026) was held in Fethiye, Türkiye, from 19 to 26 April 2026. In the “Advances in Nickelate Superconductors” session, Qisi gave an invited talk entitled “Spin and orbital excitations of trilayer nickelates.” He presented our recent RIXS results on the orbital and collective magnetic excitations of trilayer nickelates and discussed their implications for superconducting pairing.
