LLNL / qball

Qball (also known as qb@ll) is a first-principles molecular dynamics code that is used to compute the electronic structure of atoms, molecules, solids, and liquids within the Density Functional Theory (DFT) formalism. It is a fork of the Qbox code by Francois Gygi.

Density of states from Qball #39

Open AzeemaSaeed opened 2 years ago

AzeemaSaeed commented 2 years ago

Hello!

Is it possible to extract density of states from Qball? If yes how is it done? which "command" allows for the extraction/calculation of such data?

If EIGVAL is set you can see the output for the eigenvalues (and for different k-points).

These values can be can be converted to approximations of delta functions (e.g. gaussians centered at the eigenvalues) with a manually written script.

This doesn’t exploit interpolation but it is good enough if you can afford to sample enough eigenvalues (eg by making the box big or by adding k-points).
