The Coherent Potential Approximation (CPA) is a theoretical framework used in condensed matter physics to describe the properties of disordered materials, particularly systems with random disorder, such as alloy phases, where different types of atoms or ions occupy certain sites in a lattice. The main idea behind the CPA is to treat the disorder in the material in an averaged way.
