Richard B. Stephens is an Adjunct Professor in the Department of Physics and Astronomy at the University of Pennsylvania's School of Arts & Sciences. His research focuses on disordered solids, low-energy excitations in amorphous materials, and plasma physics applications in inertial confinement fusion. He has contributed to experimental and theoretical studies of laser-generated hot electrons, cone-guided fast ignition systems, and x-ray diagnostic techniques.
Education: PhD in Solid State Physics from Cornell University (1974), M.S. in Physics (1968), and A.B. in Physics (Magna Cum Laude, Honors) from the University of Pennsylvania (both 1968).
Research interests include simulating zero-energy states in disordered materials, studying a-Se glass dynamics, and advancing experimental setups for mapping state densities. His theoretical work bridges packed sphere simulations with physical systems. He collaborates with institutions like the Naval Research Laboratory and has served as Chair of the DOE HEDLP RENEW program.
Publications span plasma physics, condensed matter, and optics, with recent work addressing hot electron divergence in cone geometries and fusion target implosion dynamics. His earlier research includes surface plasmon phenomena and stress effects on amorphous materials.
