The Kohn-Sham approach is a method within density functional theory (DFT) that simplifies the many-body problem of interacting electrons in a system by introducing an auxiliary system of non-interacting electrons. This approach enables the calculation of the electron density and the properties of a quantum system using a single-particle framework while still accounting for the effects of electron-electron interactions through an exchange-correlation functional.
congrats on reading the definition of Kohn-Sham Approach. now let's actually learn it.
