Thors Hans Hansson: Composite Boson theory: mean field approximation, conformal correlators and Quantum Hall wave functions

Abstract

After a short prelude on the recent experimental results on fractional statistics in the 𝜈=1/3 Quantum Hall fluid, I will present some recent results in composite boson theory. The first part is on an extension of the theory that allows for an interpolation between the physical theory, and a model where the mean field approximation can be convincingly justified. The second is about a method to use the the mean field composite boson theory to  derive abelian QH wave functions directly in terms of correlators in a conformal field theory, and in particular I will explain how this helps us to understand the origin of orbital spin.
