Doping dependence study of CDW and its excitations via high resolution RIXS

ORAL

Abstract

Although it is now well established a charge order (CO) is ubiquitous high-temperature superconducting cuprates, its doping dependence, interplay with superconductivity, and more importantly, its relevance to the putative quantum critical fluctuation inside the superconducting dome remain an active area of research. To gain further insights, it is necessary to conduct a comprehensive doping and temperature dependence study. High energy resolution momentum-resolved resonant inelastic soft x-ray scattering (RIXS) experiments at the Cu L3-edge has been performed on the high-temperature superconductor Bi2Sr2CaCu2O8+x with 8 different doping concentration throughout the phase diagram, including antiferromagnetic, underdoped, optimally doped, and overdoped regime, at the superconducting critical temperature Tc and well below the Tc. Doping and temperature dependence of the CDW, the associated phonon softening, and excitations will be discussed.
