exciting is a full-potential all-electron density-functional-theory (DFT) package based on the linearized augmented plane-wave (LAPW) method. It can be applied to all kinds of materials, irrespective of the atomic species involved, and also allows for the investigation of the atomic-core region. exciting particularly focus on excited state properties, within the framework of time-dependent DFT (TDDFT) as well as within many-body perturbation theory (MBPT).

Have a look at the features which are already implemented or are in the development process. We are also working on tools, interfacing exciting with packages operating on the next higher length scale.

exciting is developer-friendly through a clean and fully documented programming style, a modern source-code management, a dynamical build system, and automated tests. At the same time it is user-friendly, comprising various tools to create and validate input files and to analyze results. Powerful packages are nourished from world-wide collaborations. Hence we are aiming at an open, transparent development process and encourage contributions from outside.
