-------------------------------------------------------------------------- SEMINAR OF THE DYNAMICAL SYSTEMS GROUP Institute for Computational Sciences and Informatics --------------------------------------------------------------------------- TIGHT-BINDING TOTAL ENERGY CALCULATIONS FOR METALS D.A. Papaconstantopoulos Naval Research Laboratory Washington D.C. We have applied a new tight-binding total energy method1 to calculate equations of state, defect energies, elastic constants and phonon spectra in metals. The approach does not rely on the construction of a pair potential and produces results at the same level of accuracy as first principles methods, with remarkable gains in computer speed. I will present results on a variety of metals including the 29-atom unit cell of alpha-Mn. 1R.E. Cohen, M.J. Mehl and D.A. Papaconstantopoulos, Phys. Rev.
