Physics and Materials Science 023 Fig. 3 : Anisotropic momentum dependence of phonon intensity and dispersive CO excitations in La 2−x Sr x CuO 4 (x = 0.45). (a,c) Elastic intensity maps and (b,d) inelastic RIXS intensity maps for visualizing the CO correlation and phonon branches along ( H, 0 ) and ( H, H ) directions, respectively. (e–g) Integrated intensity for buckling phonon, acoustic phonon, and CO correlation, respectively, along both directions. [Reproduced from Ref. 1] orders and suggests that charge order is prevailing in the overdoped metallic regime.
