    Spherical wave transformations leave the form of spherical waves as well as the laws of optics and electrodynamics invariant in all inertial were defined between and by Harry Bateman and Ebenezer Cunningham, with Bateman giving the transformation its name. They correspond to the conformal group of "transformations by reciprocal radii" in relation to . A method of approximating the energy states of electrons in a crystal lattice; the potential is assumed to be spherically symmetrical within spheres centered at each atomic nucleus and constant in the interstitial region, wave functions (the augmented plane waves) are constructed by matching solutions of the Schrödinger equation within each sphere with plane-wave solutions .

It followed a complete reworking of the ASW method, which is summarized in my recent book published as a Lecture Notes in Physics. The projector augmented wave method is an extension of augmented wave methods and the pseudopotential approach, which combines their traditions into a unified electronic structure method. After describing the underlying ideas of the various approaches let us briefly review the history of augmented wave methods and the pseudopotential by:

Yet, they were all more or less based on the original code. Overview Since its invention in the late seventies the Augmented Spherical Wave (ASW) method has become one of the most widespread methods used for density functional based electronic structure calculations.

Its minimal basis set allows for a natural interpretation of materials properties and makes it one of the fastest allelectron methods.

The linearized augmented planewave (LAPW) method [1] is a method for solving the equations of DFT. Modern implementations allow for a number of approximations to exchange and correlation (LDA, GGA, and LDA+U, among others) and make no approximations to the shape of the crystal potential, unlike methods employing the atomic sphere approximation.

The projector augmented wave method (PAW) is a technique used in ab initio electronic structure calculations. It is a generalization of the pseudopotential and linear augmented-plane-wave methods, and allows for density functional theory calculations to be performed with greater computational efficiency.

Valence wavefunctions tend to have rapid oscillations near ion cores. The Augmented Spherical Wave Method by Volker Eyert - free mobi epub ebooks download. vanish due to the orthonormality of the spherical harmonics.

In evaluating the remaining terms we start with the first term on the right-hand side of (), namely, the integral over the unit cell, which has to be built with the pseudo functions.

The Augmented Spherical Waves (ASW) method The ASW method is one of the most efficient methods for calculating electronic and magnetic properties of real solids.

It is used to solve the one-particle Kohn-Sham equations by which the crystalline solid is. The Augmented plane-wave method (APW) The APW method was developed by Slater in Since the effective crystal potential was found to be constant in most of the open spaces between the cores, the APW method begins by assuming such a muffin-tin potential.

The potential is that of a free ion at the core, and is strictly constant outside the core.In the same way as in the APW method, the wave function of an electron with the wave vector k + G outside the MT sphere is given by Eqn 10 and is expanded into spherical harmonics in Eqn However, there are two parameters A k + G ℓ m and B k + G ℓ m to be determined in Eqn   For that, the plane wave is expanded in spherical harmonics and by requiring equality on the boundary of the sphere we fix the expansion coefficients and so we obtain the augmented plane wave.

In the process we limit the maximum azimuthal quantum number to some max value (currently 8 in the project).
