Abstract: We study how multiple charge excitations appear in the resonant inelastic x-ray scattering (RIXS) spectra of metals. The single excitations in the problem are the plasmons and electron-hole pairs, and multi-excitation processes are usually neglected.… read more here.

DOI: 10.1103/physrevb.104.l020510
Abstract: We provide a unified interpretation of both paramagnon and plasmon modes in high-Tc copperoxides, and verify it quantitatively against available resonant inelastic x-ray scattering (RIXS) data across the hole-doped phase diagram. Three-dimensional extended Hubbard model,… read more here.

DOI: 10.1103/physrevb.96.115117
Abstract: The asymmetry between electron and hole doping in high critical-temperature superconducting (HTS) cuprates is key information for the understanding of Cooper pair formation mechanisms. Despite intensive studies on different cuprates, a comprehensive description of related… read more here.
