"Dualities in Quantum Hall Physics"

Coffee and cookies will be served at 3:45pm in RLM 4.102

Abstract: Dualities are a powerful concept in quantum field theory, helping us to identify to correct low energy degrees of freedom. In this talk several old and many new dualities in 2+1 dimensions will be shown to all follow from one conjectural base pair, with potential applications to the physics of the quantum Hall effect.
