Electron-phonon coupling is a fundamental phenomenon in condensed matter physics that describes the interaction between the movement of electrons and the vibrations of atoms within a crystal lattice. This coupling plays a crucial role in determining the electronic and thermal properties of materials, such as electrical conductivity, thermal conductivity, and superconductivity. Understanding electron-phonon coupling is essential for developing new materials with desired properties for electronic and energy applications. Research in this area involves theoretical modeling, computational simulations, and experimental measurements to explore the complex interplay between electron and phonon dynamics in materials.
