Physical Implications of the Chiral Anomaly - from Condensed Matter Physics to Cosmology
Prof. Jürg Fröhlich (ETH Zürich)


To start with, I recall what the chiral anomaly is. I then illustrate the 2D chiral anomaly and some of its uses by discussing the anomalous chiral edge currents in 2D electron gases exhibiting the quantum Hall effect. A closely related topic - analyzed next - is the theory of planar time-reversal invariant topological insulators with chiral edge spin currents. Time permitting, I will also outline a general approach to the theory of 3D topological insulators. The lecture will conclude with an application of the chiral anomaly in cosmology.
