Doping Dependence of Charge Density Wave in Bi-2212 Cuprate Superconductors
ORAL
Abstract
The origin of the charge density wave (CDW) in high-temperature superconductor, its interplay with superconductivity, and more importantly, to which extent it influences lattice and charge degrees of freedom remain an active area of research. To gain further insights into these questions, it is necessary to characterize its doping and temperature dependence. We performed high energy resolution momentum-resolved resonant inelastic soft x-ray scattering (RIXS) experiments at the Cu L3-edge on the high-temperature superconductor Bi2Sr2CaCu2O8+x with the doping level across the entire phase diagram (Antiferromagnetic, underdoped, optimally doped, and overdoped). Doping dependence of the CDW, the associated phonon softening, and excitations will be discussed.
