Abstract

Simulation experts win Dirac Medal Condensed-matter theorists Roberto Car of Princeton University in the US and Michele Parrinello of the Swiss Federal Institute of Technology (ETH Zurich) have won the 2009 Dirac Medal for their work on numerical-simulation techniques. The pair began developing new methods of modelling molecular dynamics in the mid-1980s, using elements of density functional theory and Newtonian molecular dynamics to calculate the mechanical motion of atoms and molecules in real time. Now known as the Car-Parrinello method, their technique has become a standard tool in computational physics and chemistry. The award, which is announced each year on 8August, Dirac's birthday, carries a cash prize of $5000 and is sponsored by the Abdus Salam International Centre for Theoretical Physics in Trieste, Italy.
