The density-functional toolkit, DFTK for short, is a library of Julia routines for experimentation with plane-wave density-functional theory (DFT), as implemented in much larger production codes such as Abinit, Quantum Espresso and VASP.
The unique feature of this code is its emphasis on simplicity and flexibility with the goal of facilitating methodological development and interdisciplinary collaboration. In about 5k lines of pure Julia code we already support a sizeable set of features, after just a good year of development. Our performance is of the same order of magnitude as established packages.
For getting started with DFTK, see our documentation:
Note that at least Julia 1.3 is required.
