"Quantum Hall tunnel junctions: Natural settings for Luttinger liquid physics and quantum coherence effect"

Abstract:
I will talk about some exotic physics we can learn by studying Quantum Hall tunnel junctions in various settings. In particular, I will present our theoretical picture on the physics of Quantum Hall line junction observed in recent experiments. I will also talk about our work in progress, in which we are investigating a clear cut signature of fractional statistics in Quantum Hall Jain states. In this on going project, we have noted more boson like behavior for some filling factors and more fermion like behavior for some other filling factors.
