The QDD code package and its mean field (nuclear and electronic) precursors
The open source version of QDD is built on our previous 3D implementation of real-time Time Dependent Density Functional Theory (TDDFT) PW-Teleman, originally for the analysis of cluster dynamics and later on extended to the description of molecules and clusters and molecules in contact with an environment (matrix, surface, liquid…). Code developments were shared between Erlangen and Toulouse involving numerous developers. We have also developed 1D and 2D codes for exploratory and development studies as well as a semi-classical methods.
