Professor Thors Hans Hansson from Stockholm University will give us a series of lectures at TDLI Meeting Room N600 during October 11-25, please see below for more details:
Title: Effective Field Theories for Quantum Hall liquids
Abstract: Prof. Hansson will start with some QH basics and then concentrate on how model QH liquids using quantum field theory.
