Approaches
SPEAKER:
Professor Weitao Yang,
Department of Chemistry
Duke University
TIME: Thursday Nov. 11, 2004 at 4 PM
PLACE: George P. Williams, Jr. Lecture Hall, (Olin 101)
Refreshments will be served at 3:30 PM in the lounge.
All interested persons are cordially invited to attend.
ABSTRACT
The development of linear-scaling and multi-scale methodologies and
their applications to biological systems will be presented.
These methods extend the realm of quantum mechanical theory to complex
systems that are otherwise beyond the reach of conventional approaches.
Simulations of the complex mechanics of polymers in single-molecule
atomic force microscopy experiments (AFM) and simulations of chemical
reactions in enzymes will be featured.
