RIXS Investigation of superconducting cuprate YBa2Cu4O8

The double-chain cousin of the well known YBa2Cu3)4 compounds has not been throughly investigated so far. With our preliminare measurements we already found a charge density wave excitation that was unknown. We are planning to fully characterize it and also investigate the magnetic excitations as a function as the incident energy.知名YBa2Cu3O4化合物的双链同系物至今尚未得到充分研究。通过初步测量，我们已发现一种此前未知的电荷密度波激发（charge density wave excitation）。我们计划对其进行全面表征，并研究磁激发（magnetic excitations）随入射能量（incident energy）的变化关系。
