FAPbBr3_vacancies_psiflow

A repository for the paper about the effect of vacancies on the structural properties of FAPbBr3

This repository consists of three folders:

  • psiflow_files: contains the input files for the active learning via psiflow.
    *hortense.yaml: contains the configuration settings for parsl, this selects the requested resources for the three different type of simulations (AI reference, MLP training, and MLP MD)
    *run_sequential_learning.py: the main python script, which performs the psiflow active learning workflow.
    *submitscript.sh: submits the python job to our local HPC, and loads the psiflow module (version 3.0.0)
    *data: contains the input settings for CP2K, and the initial structures dataset
    *output_final_iteration: contains the training and validation set, the log files, and the deployed and undeployed model of the last iteration of the active learning loop

  • MLP_MDs_yaff: contains the input files for the MDs performed with the final MLP constructed with psiflow. From these MDs the Pb-Br-Pb bond angles distribution is extracted, the post-analysis python script to construct these figures is also present in this folder.
    *each folder contains the input files for a separate MD simulation. The name indicates how many vacancies are present in the initial structure.
    *themodel.tar.gz: the MACE model is tarred (to reduce the size of the file).
    *shortMD.py: python script to perform the MLP MDs via yaff and ASE.
    *create_snapshot_cifs: post-analysis script which extracts random snapshots and an average snapshot for all MDs.
    *get_angle_dist: post-analysis script which constucts the Br-Pb-Br bond angle plots (also present in this folder).
    *submitscript.sh: submits the python job to our local HPC, and loads the psiflow module (version 3.0.0).

  • temperature_investigation: also contains the psiflow_files and MLP_MDs_yaff folder. The same calculations were also performed to investigate the effect of temperature (instead of vacancies), the input files for these calculations can be found in this folder.
