Abinit is a software package based on density functional theory for calculating the properties of solids.
## What is ABINIT ? **ABINIT** is a software suite to calculate the optical, mechanical, vibrational, and other observable properties of materials. Starting from the quantum equations of **density functional theory**, you can build up to advanced applications with **perturbation theories** based on DFT, and **many-body Green's functions** (GW and DMFT). **ABINIT** can calculate molecules, nanostructures and solids with any chemical composition, and comes with **several complete and robust tables of atomic potentials**. **On-line tutorials** are available for the main features of the code, and several schools and workshops are organized each year. -
