Fluctuating charge-order correlations in the cuprate superconductor N2-xCexCuO4

ORAL

Abstract

Charge order has now been observed in several cuprate high-temperature superconductors. However, it remains unclear if the charge order is purely static or whether it also features dynamic correlations. We report a resonant inelastic x-ray scattering (RIXS) experiment on the electron-doped cuprate Nd2-xCexCuO4 (NCCO) that demonstrates the existence of charge order fluctuations. We dissect the characteristic energy scales associated with the charge order peak in momentum-space and discuss its connection to magnetic fluctuations.
