-------------------------------------------------------------------- COLLOQUIUM OF THE LABORATORY FOR COMPUTER DESIGN OF MATERIALS School of Computational Sciences (CSI 898-Sec 001) -------------------------------------------------------------------- Real-time chemical reactions via ab-initio molecular dynamics Nicola Marzari Department of Chemistry, Princeton University Electronic-structure calculations have radically changed the way we approach many problems in physics, chemistry, and materials science, providing novel and very powerful tools to probe the microscopic structure of materials. They rely on solving directly the quantum-mechanical equations for the constituent atoms, resorting thus to computational rather than real-life experiments. I shall discuss some of the recent progress in the area, and present in detail a few paradigmatic cases: the cannon ball dissociation of halogens on metals, the selective chemisorption dynamics of methane on platinum, and the high-spin/low-spin conversion in transition-metal compounds. Monday , March 26, 2001 4:30 pm Room 206, Science & Tech. I Refreshments will be served at 4:15 PM. ---------------------------------------------------------------------- Find the schedule at http://csi.gmu.edu/lcdm/seminar/schedule.html
