"The emergent "Graviton" in the Fractional Quantum Hall Effect"

Dam Thanh 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 a graviton-like

mode in fractional quantum Hall effect and its broader implications.
