Evolution of effective magnetic exchange interaction under spin dilution in SrIrSnO
Xiang Li, Yifan Jiang, Yuan Wan +1
Resonant inelastic X-ray scattering measurements reveal robust magnetic excitations in the perovskite iridates SrIrSnO. We analyzed the dispersions of the magnetic…
Observation of cooperative strong coupling between optical phonon and crystal-field excitations in a pseudo Jahn-Teller system
Fangliang Wu, Xiaoxuan Ma, Zhongwei Zhang +6
Cooperative interactions between localized electronic excitations and crystal lattice are central to the emergence of complex structural phases in materials. However, the scaling r…
Transient selection of competing order in frustrated spin Peierls systems after a quench
Jing Zhou, Yuan Wan
We study theoretically the dynamics of frustrated spin Peierls systems after a quench from the paramagnetic state to the magnetically ordered state. By constructing and numerical s…
Electric-Field Induced Spin Wave Nonreciprocity in Noncoplanar Magnets
Xiao-Hui Li, Yuan-Ming Lu, Yuan Wan
We show that an electric field can induce nonreciprocal spin wave dispersion in magnetic insulators with negligible spin-orbit coupling. The electric field controls the direction a…
Evolution from intralayer to interlayer superconductivity in a bilayer - model
Yuan Yang, Xin Lu, Yuan Wan +2
Motivated by the bilayer cuprate superconductors and nickelate superconductor LaNiO, we investigate the evolution from intralayer to interlayer superconductivity based…
Magnetic switching of phonon angular momentum in a ferrimagnetic insulator
Fangliang Wu, Jing Zhou, Song Bao +4
Circularly polarized phonons offer a new route for mediating angular momentum in solids. However, controlling phonon angular momentum without altering the material's structure or c…
