摘要

In unconventional superconductors, coupled charge and lattice degrees of freedom can manifest in ordered phases of matter that are intertwined. In the cuprate family, fluctuating short-range charge correlations can coalesce into a longer-range charge density wave (CDW) order which is thought to intertwine with superconductivity, yet the nature of the interaction is still poorly understood. Here, by measuring subtle of seconds) through X-ray photon correlation spectroscopy, we report sensitivity to both superconductivity and CDW. The atomic lattice shows remarkably faster relaxational the momentum dependence, we show that the intermediate scattering function almost monotonically scales with the relaxation distance of atoms away from their average reversed for other temperatures. These observations are consistent with an incipient of relaxational atomic fluctuations for understanding the electronic physics cuprates, which are inherently disordered due to carrier doping.
