Current Research Interests

My research in computational condensed matter physics and materials science involves developing and applying codes, based on density functional theory to the study of the properties of metals, insulators, and semiconductors. The techniques used are various forms of the augmented plane wave method and tight-binding approaches. This research covers calculations of energy bands and densities of states which lead to evaluation of Fermi surface properties and the determination of parameters controlling superconductivity via the electron phonon coupling; evaluation of magnetic moments and Curie temperatures via spin-polarized calculations. These techniques are also used in the computation of total energies used to determine the stability of crystal structures and calculate equilibrium lattice constants and mechanical properties such as elastic constants. Using the NRL tight-binding method the above first-principles approach extends to calculating the total energies of larger systems and utilizes molecular dynamics to obtain quantities such as phonon frequencies, mean-squared displacements, thermal expansion coefficients and radial distribution functions in the amorphous state.

Dimitrios A. Papaconstantopoulos was born in Athens, Greece, and graduated from the University of Athens with a B.S. degree in Physics in 1961. He received a Ph.D. in theoretical solid state physics from the University of London, England, in 1967. He was a professor of physics at George Mason University from 1967 to 1977 and Chair of the Physics Department from 1974 to 1977. He then joined the Naval Research Laboratory(NRL) as a research physicist. He was director of the Center for Computational Materials Science in the Materials and Technology Division of NRL from 1992 to 2004.

His areas of expertise are in computational condensed matter physics and include band structure calculations, theory of superconductivity, and tight-binding parametrizations. He has authored 279 journal articles and three books and has given more than 300 presentations at professional meetings. He has won four Alan Berman Research Publication awards and the 1990 Sigma Xi Pure Science Award at NRL. He has been a Fellow of the American Physical Society since 1980. He has over 9,500 citations in the scientific literature. In August 2000 he was awarded the Navy Meritorious Civilian Service Award. In August 2004 he was appointed as professor of materials science at George Mason where he had held an adjunct professorship since 1992. He has been Chair of the Department of Computational and Data Sciences at George Mason University from January 2006 to December 2010.
