Description
Understanding of the ordering tendencies exhibited by the cuprates can give valuable insight into the origin of superconductivity in these complex oxides. Thus, I will present the study of the charge density wave (CDW) order and discuss its connection with the electron-phonon coupling in Nd$_{2-x}$Ce$_x$CuO$_4$. Recent studies suggested that the CDW order can cause an anomalous softening of the longitudinal Cu-O bond-stretching phonon mode around the order’s wave vector, $q_{CDW}$. Motivated by these results, we performed temperature and doping-dependent inelastic X-ray scattering studies combined with the DFT calculations for the parent compound.
