Atomistic models

Polymers

  • The PMAP AA model can be found in the library of Polyply; the topology for a 30-mer (with state of charge = 0%) can be found in polymers/.
  • The PEPP AA model can be found in the library of Polyply; the topology for a 30-mer (with state of charge = 0%) can be found in polymers/.
  • The PVBP AA model can be found in the library of Polyply; the topology for a 30-mer (with state of charge = 0%) can be found in polymers/.

MD simulation protocol

Use the ML surrogate model to infer the electronic couplings

./PROC_MLVij_step01_predictions.bash                   # infer orbital overlaps
./PROC_MLVij_step02_plot_the_inferred_overlaps.bash    # plot the inferred orbital overlaps
./PROC_MLVij_step03_convert_to_EC_and_plot.bash        # convert to electronic couplings and plot
