Research Interests

Multiphase equations of state and phase diagrams of materials, optical properties of systems in extreme conditions of pressure and temperature, many-electron effects in optical properties of bulk solids and nanostructures, physics of highly collisional plasmas.

Personal Background

Lorin Benedict joined the Physics Division at the end of 1998 as a computational condensed matter theorist. Prior to being at LLNL, he was an NRC postdoc at the National Institute of Standards and Technology in Gaithersburg, MD, where he worked with Eric Shirley on the computation of excitonic effects in optical spectra of solids. He holds a BA in Physics from the University of Chicago (1992), and a PhD in Physics from the University of California at Berkeley (1996), where he worked in the groups of Steven Louie and Marvin Cohen. His thesis work was on predicting various properties of carbon nanotubes and other closely related materials. His current interests are two-fold: 1) Using phenomenological models to produce very accurate multi-phase equations of state for materials such as hydrogen, carbon, beryllium, etc., and 2) Investigating the physics of dense, highly collisional plasmas using MD and kinetic equations.
