Event Description
Prof. Artem R. Oganov, Dept. of Geosciences, Stony Brook University
"Discovering New Materials and New Phenomena by Simulation"
This lecture will describe how supercomputers can be used to predict and tailor novel materials. Modern computational approaches are based on concepts of evolution and natural selection—trial chemical compositions and structures (generated by the computer) are allowed to compete, mate and mutate, until the fittest (most stable or possessing the needed properties) material emerges. The results of such computer experiments can then be tested by experiment. Examples of how these approaches have been used will be explored, and the new phenomena that emerged from such studies, and experimental follow-up works. This approach will dramatically reduce the effort needed to discover new materials, speeding up the progress of mankind.
Artem R. Oganov joined the Stony Brook Geosciences department in 2008. His research is in the fields of mineral physics, computational materials science and materials design. His contributions include the development of a novel methodology for predicting crystal structures, discovery of several new minerals and novel forms of elements and compounds, development of methods for studying energy landscapes of chemical systems, development of accurate pressure scales, and extensive studies of structural stability and properties of minerals and compounds, Prof. Oganov is a founding member of the Mineralogical Crystallography group of the European Crystallographic Association, and a member of editorial boards of American Mineralogist and the Journal of Superhard Materials.
Following the lecture, there will be refreshments and an opportunity for discussion. |
