Electronic structure methods

Electronic structure methods are computational techniques used in quantum chemistry and condensed matter physics to determine the electronic properties and behavior of atoms, molecules, and solids. These methods provide insights into the arrangement and energy of electrons in a system, which is crucial for understanding chemical bonding, reactivity, material properties, and various physical phenomena. Here are some key concepts and categories of electronic structure methods: 1. **Ab Initio Methods**: These methods rely on fundamental principles of quantum mechanics without empirical parameters.
