Algorithm parameters for objective functions involving elasticity #9

Open nmashouf opened 9 years ago

nmashouf commented 9 years ago

In search of relevant parameters for our elasticity-computation-guiding algorithm, I plotted pymatgen bulk modulus data ('elasticity.K_VRH') against various material properties data and found a few interesting correlations (mostly Volume, Density, and EFermi). These graphs each only include 500 data points, so we can look into more sophisticated methods if the trends seem legitimate! (apologies for the lack of units on the graphs, but the data is pure pymatgen data so they are all in the same units as the material property defines in the documentation)

Some of them are broken. :(

Wow, I wouldn't have thought of plotting vs fermi energy. Cool, thanks for sharing!
