Colloquium: Where the Weyl Things Are

08/25/2017 - 3:30pm to 4:30pm
Speaker(s) / Presenter(s): 
Professor Nandini Trivedi (Ohio State University)
Type of Event (for grouping events):
Where the Weyl Things Are
Nandini Trivedi (Ohio State)
I will talk about Dirac and Weyl semimetals, their recent predictions and observations. They have unusual topological properties-- Berry monopoles in the bulk and chopped up Fermi arcs on the surfaces. I will discuss consequences of these topological features on magneto-thermal transport, including predictions of a novel conveyor belt entropy transport between the bulk and surface.
