Grain boundaries are Brownian ratchets

# Phase-field crystal simulations for paper "Grain Boundaries are Brownian Ratchets" Openly available Matlab simulation files used to produce the phase-field crystal results from https://www.science.org/doi/10.1126/science.adp1516 see also https://zenodo.org/records/13319941 Runable Matlab files can be found within the respective folders BICRYSTAL, POLYCRYSTAL_MAINTEXT and POLYCRYSTAL_LARGER_ACCELERATION and are named by the corresponding figures. ## UpdateSince the acceptance and publication of our paper, many friends and colleagues have been interested in whether a larger acceleration in grain growth rate through cyclic annealing can be achieved. We updated the dataset by adding a new version with an additional set of cyclic annealing simulations, indicating even more robust evidence of cyclic annealing-accelerating grain growth. The additional code can be found in the folder POLYCRYSTAL_LARGER_ACCELERATION, and the details and discussion can be found in the README file in the same folder. ## Other simulationsThe remaining input files for the MD simulations, neb calculations and python codes for the Markov modellings are not included in this repository and can instead be found under https://doi.org/10.5061/dryad.0k6djhb8v ## DisclaimerThe software is released here under the MIT license.
