"The "graviton' of the fractional quantum Hall effect"
Talk Abstract: In a fractional quantum Hall state, electrons organize themselves into a strongly interacting fluid with nontrivial emergent properties. It has recently been understood that the fractional quantum Hall fluids accomodate a spin-2 excitation, which, in certain theoretical models, is a condensed-matter analog of the graviton. In this talk we will review the basic physics of the fractional quantum Hall effect and discuss a recent experiment observing a "chiral graviton mode" and its broader implications.
