Strongly correlated electron systems represent a central challenge in condensed matter physics, where electron–electron interactions dominate over kinetic energy and give rise to unconventional electronic, magnetic, and superconducting states. Unlike conventional metals and band insulators, these systems cannot be described adequately by single-particle theories. This paper reviews the fundamental concepts of strong electronic correlations, focusing on Mott insulators, Hubbard-type models, emergent quantum phases, and experimental realizations. The implications of correlated systems for modern materials engineering and future technologies are also discussed.
