0. Related documentation

Besides the documentation available on the Web, there is a wealth of information inside the package itself, see the directory "doc". The reader might consult the latest version of the "doc/users/context.txt" file for the description of the ABINIT project and its history. The different versions of the "doc/release_notes/*html" files will allow to see the actual development of the project since version 1.5, released in August 1998. They give also an idea of on-going developments. Discussions on the forum might also allow to get documentation.

1.H. Verification (cross checking with other codes).

  • 1.H.1. The ground state total energy, geometry relaxation, phonon frequencies, electron-phonon matrix elements, temperature dependence of the electronic gap has been cross checked with Quantum Espresso and YAMBO. See S. Poncé and G. Antonius and P. Boulanger and E. Cannuccia and A. Marini and M. Côté and X. Gonze, Verification of first-principles codes: Comparison of total energies, phonon frequencies, electron--phonon coupling and zero-point motion correction to the gap between ABINIT and QE/Yambo. Computational Materials Science 83, 341 (2014).
  • 1.H.2. It is possible to choose the same convention for the definition of the average eletrostatic potential, than Quantum Espresso, allowing verification of results for charged systems. See F. Bruneval, J.-P. Crocombette, X. Gonze, B. Dorado, M. Torrent and F.
