论文摘要
$ \ rm SR_2IRO_4 $的颗粒孔刺激的高能量集体模式使用$ j = 1/2 $和$ 3/2 $的状态从Spin-Orbit Coupling coupling coupling coupling构成。这些集体模式具有适当的相互作用强度和重新归一化的自旋轨道间隙，产生了两个定义明确的繁殖旋转轨道激子模式，其能量尺度和分散与与抗弹性X射线散射（RIXS）测量非常吻合。
The high-energy collective modes of particle-hole excitations across the spin-orbit gap in $\rm Sr_2IrO_4$ are investigated using the transformed Coulomb interaction terms in the pseudo-spin-orbital basis constituted by the $J=1/2$ and $3/2$ states arising from spin-orbit coupling. With appropriate interaction strengths and renormalized spin-orbit gap, these collective modes yield two well-defined propagating spin-orbit exciton modes, with energy scale and dispersion in excellent agreement with resonant inelastic X-ray scattering (RIXS) measurements.
