What are the key features and applications of the Holstein model in the field of quantum mechanics?

Answer 1

The Holstein model is a theoretical model used in quantum mechanics to study the interaction between electrons and lattice vibrations in solid materials. Its key features include considering both electronic and vibrational degrees of freedom, and it is often used to study phenomena like electron-phonon coupling and charge transport in materials. Applications of the Holstein model include understanding superconductivity, thermal transport, and other properties of materials at the quantum level.
