What Does FLAPW Stand For?

FLAPW stands for Full Potential Linearized Augmented Plane Wave

FLAPW, or Full Potential Linearized Augmented Plane Wave, is a computational method used in quantum mechanics and solid-state physics for calculating the electronic structure of materials. It combines the advantages of full potential techniques, which do not rely on spherical approximations around atomic sites, with linearized augmented plane wave functions, enabling accurate determinations of energy bands, density of states, and electronic wave functions. This approach is particularly effective for complex materials with varying local geometries and electronic properties, providing insights into fundamental interactions within solids.
