The electrons in solids interacting via Coulomb interaction obey the law of quantum mechanics. Furthermore, the relativistic effect is often enhanced since the velocities of electrons are rather fast due to the strong binding potential of the atomic nuclei. Starting from these fundamentals of solid state physics, we will explore theoretically the new functionalities of the strongly correlated electronic systems. Especially, the special focus will be put on the development of "quantum electrodynamics" in solids and its consequent "cross correlation effect". We will create new device concepts by combining the field theoretical approach, computer simulations, and the first-principles band calculations, with the close collaboration with the experimental groups.
