嘉宾简介

　　Russell J. Hemley holds the position of Distinguished Chair in the Natural Sciences at the University of Illinois at Chicago. His research explores the behavior of matter and materials in extreme environments, notably high pressures and temperatures, with applications to fundamental physics and chemistry, materials science and technology, and earth and planetary science. He received his B.A. from Wesleyan University, and M.A. and Ph.D. from Harvard University, all in chemistry. He is a Member of the National Academy of Sciences, Fellow of the American Academy of Arts and Sciences, Corresponding Fellow of the Royal Society of Edinburgh, Honoris Causa Professor of the Russian Academy of Sciences, and is a recipient of the Balzan Prize and Percy W. Bridgman Award, among other honors. He has directed national materials science centers funded by the DOE, DoD, and NSF, and currently directs three such centers at UIC, including the Chicago/DOE Alliance Center (CDAC). He has co-authored approximately 720 scientific publications. His recent research at UIC has focused on the design, discovery, and synthesis of novel energy materials, including the discovery of near room temperature superconductors.

讲座摘要

　　Superconductivity in the vicinity of room temperature has the potential to revolutionize numerous technologies as well as our understanding of condensed matter. Inspired by theoretical predictions for hydrogen-rich materials under pressure, previous work from our group has established the existence of near-room temperature superconductivity at megabar pressures, now reproduced by numerous other groups. Recently reported evidence for superconductivity near ambient P-T conditions has been promising but controversial. First-principles calculations provide important insights into the behavior of this remarkable class of materials. There are prospects for ever higher Tc superconductivity in more complex hydrides as well as in other systems such as cuprates over a range of pressures.
