Comparison of DFT calculations with experimental results of inelastic X-ray scattering: (a) phonon energies in L a 1 . 8 5 S r 0 . 1 5 C u O 4 and (b) in Y B a 2 C u 3 O 7 ; (c) phonon line-widths in L a 1 . 8 5 S r 0 . 1 5 C u O 4 . DFT calculations [28] give much smaller width than experiments [173ā€“175]. From [178].
