- Physics Department Colloquium
- The emergent "graviton" of the fractional quantum Hall effect
- Time: 3:30 pm - 5:00 pm
- Place: Chamberlin 2241
- Speaker: Dam T. Son, University of Chicago
- Abstract: In fractional quantum Hall states, electrons self-organize into a strongly interacting fluid with nontrivial emergent properties. It has recently been understood that fractional quantum Hall fluids accommodate one or several spin-2 excitations, which have been argued to be condensed-matter analogues of the graviton. In this talk we will review the origin of the idea of the graviton and the basic physics of the fractional quantum Hall effect. We then discuss a recent experiment claiming observation of "chiral graviton modes" and its broader implications.
