Subject: 15.03.05 Webinar presented by Prof. M. Head-Gordon, "Combinatorial design of new density functionals using a 'survival of the most transferable' approach"
Registration: https://attendee.gotowebinar.com/register/9124668143157483010 Time: 1pm - 2pm EST Summary: The accuracy and efficiency of large-scale density functional theory (DFT) calculations is an issue that is central to the ability of computational chemistry to solve practical problems. At the heart of this issue is the design of more accurate and more transferable density functionals that yield the very high accuracy needed for both intermolecular and intramolecular interactions. We describe the development of two new density functionals, a new range-separated hybrid GGA, ÏB97X-V, and a meta GGA, B97M-V, using a combinatorial method. The resulting functionals are compared against leading existing functionals on a broad variety of test cases. It is shown that substantially fewer parameters are required than have been commonly employed, and that very significant improvements in accuracy for intermolecular interactions can be obtained, as well as significant improvements in accuracy for bonded interactions. Presenter: Martin Head-Gordon is the Kenneth S. Pitzer Distinguished Professor of Chemistry at the University of California at Berkeley and the Scientific Advisor to Q-Chem, Inc. Dr. Head-Gordon's research group centers on the development of new electronic structure theory methods, and their implementation as efficient computer algorithms. He is recognized with many awards, such as the Medal of the International Academy of Quantum Molecular Sciences (1998) and his election to the American Academy of Arts and Sciences (2011) and the American Chemical Society Fellow (2012).NOTE THAT E-MAIL ADDRESSES HAVE BEEN MODIFIED!!!
