Theory of Spin-Excitation Anisotropy in the Nematic Phase of FeSe Obtained From RIXS Measurements

Recent resonant inelastic x-ray scattering (RIXS) experiments have detected a significant
high-energy spin-excitation anisotropy in the nematic phase of the enigmatic iron-based
superconductor FeSe, whose origin remains controversial. We apply an itinerant model
previously used to describe the spin-excitation anisotropy as measured by neutron
scattering measurements, with magnetic fluctuations included within the RPA
approximation. The calculated RIXS cross section exhibits overall agreement with the
RIXS data, including the high energy spin-excitation anisotropy
