Physics / SAJEEV, JOHN


University Professor, Department of Physics, University of Toronto, Canada.

Research interests

Condensed matter physics, disordered systems, optical properties, localization, many-body theory, magnetism, superconductivity.

Professor John is one of the world's leading condensed-matter theorists. His work on the propagation of light in matter has transformed our understanding of that field. His name is synonymous with the field that has become known as "photonic crystals." The term "photonic crystals" refers to a new class of artificial optical materials that will almost certainly form the basis of revolutionary new technologies in the 2lst century. The basic concept was developed in a series of papers by Professor John in the 1980's.
