Rixs investigation of the double-chain cuprate YBa2Cu4O8

Using RIXS we found a charge density wave in the double-chain cuprate YBa2Cu4O8, which was not previously found. With this experiment we aim to fully characterize this CDW with fine temperature and energy dependencies.

本研究利用共振非弹性X射线散射（Resonant Inelastic X-ray Scattering, RIXS）技术，在双链铜基化合物YBa₂Cu₄O₈中发现了此前未曾报道的电荷密度波（CDW）。本次实验旨在通过精细的温度与能量依赖特性分析，对该电荷密度波进行全面表征。
