Tutorials

These tutorials provide an overview about typical workflows to perform DFT+DMFT calculations with solid_dmft. The tutorials are sorted by complexity and introduce one after another more available features.

Note

The tutorials are run with the 3.1.x branch of triqs. Please use the 3.1.x branch for triqs and all applications to reproduce the results shown here.

Short description of the tutorials linked below:

1. Typical one-shot (OS) DMFT calculation based on prepared hdf5 archive for SrVO3
