Session S3 - Non-abelian States in Quantum Systems.
INVITED session, Wednesday afternoon, March 24
518AC, Palais des Congres
We study the groundstates of interacting Bose gases at high angular momentum. We discuss both the case of energy-independent repulsion, and the case where interactions are strongly affected by a nearby Feshbach resonance. We show that exact groundstates at high angular momentum can be found analytically for a general and realistic model for the resonant interactions. We identify parameter regimes where the exact groundstates are exotic fractional quantum Hall states, the excitations of which obey non-abelian exchange statistics.
