Opw method

WebThe OPW method has been brought into the modern framework of total energy functionals by the projector augmented wave (PAW) approach that uses pseudopotential operators … WebThis chapter describes some of the energy band calculations that have been made at M.I.T. To carry out the calculation in a practical fashion, one derives a secular equation connecting the various plane waves, each supplemented by its spherical part inside the spheres; it is now customary to refer to such a function as an augmented plane wave (APW).
