What is ABINIT ?
ABINIT is a package whose main program allows one to find the total energy,
charge density and electronic structure of systems made of electrons and nuclei (molecules and periodic solids)
within Density Functional Theory (DFT), using pseudopotentials and a planewave or wavelet basis.
ABINIT also includes options to optimize the geometry according to the DFT forces and stresses,
or to perform molecular dynamics simulations using these forces, or to generate dynamical matrices,
Born effective charges, and dielectric tensors, based on Density-Functional Perturbation Theory, and many more properties. Excited states can be computed within the Many-Body Perturbation Theory (the GW approximation and the Bethe-Salpeter equation), and Time-Dependent Density Functional Theory
In addition to the main ABINIT code, different utility programs are provided.
ABINIT is a project that favours development and collaboration (short presentation of the ABINIT project - 10 pages in pdf).
