 John Hubbard (physicist)

John Hubbard is an American physicist known for his contributions to condensed matter physics, particularly in the area of strong correlation phenomena in electrons and the study of complex systems. He is best known for developing the Hubbard model, which is a mathematical model used to describe the interactions of electrons in lattice structures and has been a crucial framework for understanding various physical systems, including superconductors and other correlated electron systems.
