Exciting is a state-of-the-art full-potential linearized augmented plane wave (FP-LAPW) code which uses quantum mechanics, specifically density functional theory (DFT), to determine the physical properties of solids and molecules. Augmented plane waves provide an almost ideal basis set for computing the Hamiltonian matrix for a periodic solid, and allow for tightly bound core and semi-core electrons to be treated on the same footing as valence electrons.

The EXCITING code is designed so that new methods in DFT can be implemented quickly and reliably. For example, it is currently the only code available that can perform exact exchange optimized effective potential (EXX-OEP) calculations for non-collinear systems with full treatment of the core-valence interaction.

EXCITING is freely available and released under the GNU General Public License.

In 2009 the code has split into two branches – “exciting”, primarily developed at the University of Leoben, and “elk”, primarily developed at the Free University of Berlin and at the Max Planck Institute for Microstructure Physics.

Famous quotes containing the word exciting:

    Some men tend to cling to old intellectual excitements, just as some belles, when they are old ladies, still cling to the fashions and coiffures of their exciting youth.
    Jane Jacobs (b. 1916)

    What an exciting age it is we live in
    With all this talk about the hope of youth
    And nothing made of youth.
    Robert Frost (1874–1963)

    I would sum up my fear about the future in one word: boring. And that’s my one fear: that everything has happened; nothing exciting or new or interesting is ever going to happen again ... the future is just going to be a vast, conforming suburb of the soul.
    —J.G. (James Graham)
