Geometry and Topology in two-dimensional Chiral Liquids

Hans Hansson, University of Stockholm

Weekly Theory Seminar.


I will explain in simple terms what are two-dimensional chiral liquids, and why they are interesting objects to study. I quickly specialize to Quantum Hall liquids and topological superconductors and explain the concept of orbital spin and how it can be related to observable quantities. I will then introduce “Majorinos” or  “half fermions” that are signatures of odd pairing topological phases, and discuss a couple of amusing thought experiments where geometrical effects play an important role. The talk is aimed at a general theoretical physics audience.

(The slides will be available here)
