Data for: Photoinduced correlations in stochastic dynamics of a solid-state ionic conductor

Photoexcitation by ultrashort laser pulses plays a crucial role in controlling reaction pathways, creating nonequilibrium material properties, and offering a microscopic view of complex dynamics at the molecular level. The photo response following a laser pulse is, in general, non-identical between multiple exposures due to spatiotemporal fluctuations in a material or the stochastic nature of dynamical pathways. However, most ultrafast experiments using a stroboscopic pump-probe scheme struggle to distinguish intrinsic sample fluctuations from extrinsic apparatus noise, often missing seemingly random deviations from the averaged shot-to-shot response. Leveraging the stability and high photon flux of time-resolved X-ray micro-diffraction at a synchrotron, we employed established statistical tools to quantitatively characterize the stochastic behavior of the photoinduced dynamics in a solid-state electrolyte. By analyzing temporal evolutions of the lattice parameter of a single grain in a..., , # Data for: Photoinduced correlations in stochastic dynamics of a solid-state ionic conductor

## Description of the data and file structure

The raw data consists of a series of X-ray diffraction images as a function of time. These were processed in Igor Pro 8 to yield the time-resolved lattice constant of Lithium Lanthanum Titanate (Angstrom units).

### Files and variables

#### File: LLTO_Data_Repository.zip

**Description:** The repository consists of all data from each figure in the main and supplementary materials. Within each figure subfolder, a ReadMe.txt will describe the contents, with units.

#### File: Code.zip

Folder \"Igor_Scripts.zip\" contains all necessary scripts to analyze and simulate the data. All of the analysis and simulation were performed in Igor Pro 8.

## Code/software

Code and scripts can be found in the folder \"code.zip\" with individual ReadMe.txt files within each subfolder.
