[PAST EVENT] Colloquium - Anton Burkov (University of Waterloo)
December 4, 2015
4pm - 5pm
Abstract:
I will describe the recently discovered new state of condensed matter, Weyl semimetal.
Closely related Dirac semimetals will also be mentioned. I will describe the most basic physical properties of Weyl semimetals, focusing on the properties that follow from the nontrivial electronic structure topology, e.g. the Fermi arc edge states. Novel transport phenomena, such as the large negative longitudinal magnetoresistance, characteristic of Weyl semimetals, will be described as well.
I will demonstrate that these are also rooted in the nontrivial electronic structure topology.
Connections to particle physics, in particular the chiral anomaly, will be discussed.
