Condensed-Matter Physics & Materials Science Seminar

"Topological Insulators and Dirac Semimetals - Recent Progress in New Materials"

Presented by Robert J. Cava, Princeton University

Thursday, March 31, 2016, 10:00 am — Large Seminar Room, Bldg. 510

"New materials give new properties" describes the goal of our solid state chemistry research program. This goal would be much easier to attain if there was a reliable way to predict the stability of an unknown non-molecular solid, then predict what its properties would be, then make it as a real material and then finally test it, but unfortunately that is not the case; establishing such a process is the grand challenge in contemporary solid state chemistry, and so we have to operate differently. Our discussions with experimental and theoretical physicists teach us about current issues in the electronic and magnetic properties of matter, and our chemistry background teaches us how to think about crystal structures and bonding; our work is about trying to put these two cultures together to find new materials. In this talk I will describe some of our recent results in Topological Insulators and Dirac and Weyl Semimetals.
