Abstract = {{Experimental evidence on high-T-c cuprates reveals ubiquitous charge
   density wave (CDW) modulations(1-10), which coexist with
   superconductivity. Although the CDW had been predicted by theory(11-13),
   important questions remain about the extent to which the CDW influences
   lattice and charge degrees of freedom and its characteristics as
   functions of doping and temperature. These questions are intimately
   connected to the origin of the CDW and its relation to the mysterious
   cuprate pseudogap(10,14). Here, we use ultrahigh-resolution resonant
   inelastic X-ray scattering to reveal new CDW character in underdoped
   Bi2.2Sr1.8Ca0.8Dy0.2Cu2O8+delta . At low temperature, we observe
   dispersive excitations from an incommensurate CDW that induces
   anomalously enhanced phonon intensity, unseen using other techniques.
   Near the pseudogap temperature T{*}, the CDW persists, but the
   associated excitations significantly weaken with an indication of CDW
   wavevector shift. The dispersive CDW excitations, phonon anomaly, and
   analysis of the CDW wavevector provide a comprehensive momentum-space
   picture of complex CDW behaviour and point to a closer relationship with
   the pseudogap state.}},
