Projector Augmented Wave (PAW) Method

The Projector Augmented Wave (PAW) method is a computational technique used in quantum physics to efficiently and accurately simulate how electrons behave in materials. It combines the strengths of two approaches: the precise treatment of electron interactions near atomic nuclei (core regions) and simplified models farther away (valence regions). By "projecting" complex wavefunctions onto simpler forms within specific regions, PAW allows scientists to analyze materials at the atomic level without excessive computational cost, enabling better understanding of properties like conductivity, magnetism, and chemical reactivity.
