Kohn's Algorithm is a computational method used in quantum chemistry to solve the electronic structure of many-body systems. It is particularly effective for calculating the ground state energy of electrons in atoms and molecules by utilizing the principles of density functional theory (DFT). The algorithm simplifies complex interactions by focusing on electron density rather than wave functions. The algorithm operates by iteratively updating the electron density until it converges to a stable solution. This approach allows for efficient calculations, making it suitable for large systems where traditional methods may be computationally prohibitive. Overall, Kohn's Algorithm has significantly advanced the field of theoretical chemistry.
