Anomalous lattice relaxation dynamics in optimally doped La2โxSrxCuO4
(2025) In Physical Review B 112(10).- Abstract
- The atomic lattice plays a critical role in the emergence of high-๐๐ superconductivity in cuprates. While the dynamics associated with electron-lattice coupling typically unfold on picosecond-to-femtosecond timescales, we present an x-ray photon correlation spectroscopy investigation on an optimally doped La-based cuprate that reveals a strong response of kilosecond-scale lattice relaxation dynamics to the superconducting state. Notably, an anomaly emerges around ๐๐: upon cooling into the superconducting state, the average atomic relaxation lifetime decreases, i.e., dynamics accelerate. This indicates a significant change in the local disorder-induced strain field dynamics at the superconducting transition,... (More)
