Fig. 6: Energy cuts of the magnetic excitation spectrum in K2Co(SeO3)2 in the supersolid phase.
From: Wannier states and spin supersolid physics in the triangular antiferromagnet K2Co(SeO3)2
Energy cuts through the INS data shown in Fig. 5 at representative wave vectors as indicated. Both longitudinal and transverse spin fluctuations contribute to scattering, the intensity being proportional to Szz(q, ω) + S⊥(q, ω). a K point, b M point, c half way between K and M, d half way between Γ and K, and e half way between M and Γ. The solid lines represent QMC calculations for Szz(q, ω) only. An arbitrary global scale factor is applied to match the intensity of the M point. The measured spectra have been averaged over equivalent wave vectors accessible in the experiment. Note the y-axis is in logarithmic scale. Insets show the same plot with y-axis in linear scale. Shaded Gaussians represent the energy resolution. The dashed lines are fits to a constant background and the elastic scattering peak.
