Temperature Dependence of CDW phenomena in optimally-doped Bi2212 via RIXS

ORAL

Abstract

Charge density wave (CDW) in double-layered Bi-2212 copper oxide superconductor has long been studied by STM; yet the questions of how the CDW’s origin and how it interacts with other degrees of freedom as a function of temperature still remain largely unexplored. Here we utilize high-resolution resonant inelastic x-ray scattering (RIXS) at the Cu L-edge to investigate the CDW in optimally-doped Bi2212. A CDW scattering in the quasi-elastic region can be clearly observed, unambiguously demonstrating that CDW is a bulk property and exist in the optimally-doped Bi2212. Its temperature dependence and interaction with the phonon degrees of freedom will also be discussed.
