Stephen Cotanch

Professor Emeritus

Riddick Hall 102


Professor Cotanch received his PhD in 1973 from the Florida State University. He was a visiting graduate student at Princeton University for the 1971-72 year and a postdoctoral research associate at the University of Pittsburgh from 1973 to 1976. He joined NC State University as Assistant Professor in 1976.  In 1985 he was a Visiting Professor at the University of Melbourne, Australia.

Area(s) of Expertise

His research contributions center on many-body techniques to diagonalize effective Hamiltonians, describing the complex behavior of systems of fermions and bosons interacting via the electromagnetic, weak and strong nuclear forces (including Quantum Chromodynamics). He advanced the understanding of the structure of nuclei, hypernuclei and elementary particles, especially exotic glueballs and hybrid mesons containing color confined gluons and quarks. He developed improved scattering and reaction formulations for direct nuclear reactions, photonuclear processes and K meson scattering and production. He also collaborated with experimentalists, including proposed particle measurements and detector design, and he derived several novel constraint relations and theorems from fundamental principles and symmetries to assist experimental analysis.
