Add to Calendar 3/26/2018 12:00 pm 3/26/2018 America/Chicago ICMT Seminar: "Quantum critical scaling laws of Weyl semimetals " DESCRIPTION:

Since two topologically distinct states cannot be continuously deformed into each other, they are generally separated by an exotic critical point. In accordance with this general principle, a topologically nontrivial Weyl semimetal and a trivial insulator are separated by a quantum critical point with anisotropic dispersion relations. I will show how such a topological quantum critical point controls the scaling laws for chiral transport properties of Weyl fermions. If time permits, I will also briefly discuss the effects of quenched disorder on the scaling laws.
