 Dynamical mean-field theory

Dynamical mean-field theory (DMFT) is a theoretical framework used to study strongly correlated electron systems, particularly in the context of condensed matter physics. It is especially useful for understanding phenomena in materials where the interactions between electrons are strong and cannot be treated perturbatively. ### Key Features of DMFT: 1. **Strong Correlation Effects**: In materials with strong electron-electron interactions, many-body effects are significant.
