2016 – David M. Ceperley and Eberhard K. U. Gross
The Berni J. Alder CECAM Prize for 2016 will be jointly awarded to Professor David M Ceperley, Department of Physics, University of Illinois at Urbana-Champaign and to Professor Hardy Gross, Director of the Max Planck Institute of Microstructure Physics, Halle on November 23 2016, EPFL, Lausanne, Switzerland.
The two nominees have made fundamental ground-breaking contributions to the modern field of electronic structure calculations widely used to describe by first principles the equilibrium and excited state properties of materials and molecular structures. Even if they have not worked together they have jointly shaped the filed and many of the major achievements are based on their pioneering contributions. They have always focus their activities on fundamental questions and very carefully developed the formalism that ultimately leads to novel computational techniques.
Professor David Ceperley is one of the pioneers in the development and application of path integral Monte Carlo methods for quantum systems at finite temperature, such as superfluid helium and hydrogen under extreme conditions. He developed novel methods for stochastic computation of quantum systems and introduced and developed the Coupled Electron-Ion Monte Carlo, a first- principles simulation method to perform statistical calculations of finite temperature quantum nuclei using electronic energies. His most important contribution is the calculation of the energy of the electron gas, providing basic input for most numerical calculations of electronic structure.
Professor Hardy Gross on the other hand has made outstanding contributions to the development of time-dependent (TD) density functional theory (DFT) that are among the most influential works in computational physics. Hardy is best known for the development of time dependent density functional theory (TDDFT). But this is by no means his only contribution. He followed this up with developing superconducting density functional theory (SCDFT) and most recently the time dependent potential energy surface (TDPES). He has also made pioneering contributions to reduced density matrix functional theory (RDMFT), ultra-fast phenomena, as well as non-adiabatic processes.
This joint award recognises that they have developed genuinely complementary methods to rigorously solve the quantum many-body problem at the level of interacting electrons and nuclei .
