+The Projector Augmented Wave (PAW) method is an algorithm developed by Peter Blöchl for the quantum mechanical simulation of electrons in materials and molecules. The CP-PAW code is the first implementation of the PAW method.
+CP-PAW code relies heavily on the ab-initio molecular dynamics (AIMD) framework invented by Roberto Car and Michele Parrinello (CP). The first two letters of the name of the code are a tribute to their contribution. The PAW method has been developed to overcome the limitations of the Car-Parrinello method to pseudopotentials and to make it accessible to all-electron calculations. The PAW method borrows many concepts from the linear augmented wave methods of Ole Krogh Andersen, which are generalised and adjusted for that purpose.
+The quantum mechanical description of electrons rest on the Density Functional Theory (DFT) of Walter Kohn and its extensions.
+This page shall be the focal point for the communication and the sharing of resources among CP-PAW users.

-CP-PAW is a computer program for the calculation of the electronic and atomic structure of materials and molecules. The electrons are described quantum mechanically on the basis of density-functional theory (DFT) and the projector augmented wave (PAW) method. The motion of the atoms is described with ab-initio molecular dynamics (AIMD) in the implementation of Roberto Car and Michele Parrinello (CP).
