Research — Composite dark matter
Summary: The 2010 Nobel Prize in Physics was awarded to recognize the experimental isolation and characterization of graphene, a remarkable two-dimensional material consisting of carbon atoms arranged in a regular honeycomb lattice. Among the many unusual properties of graphene, in the context of lattice field theory the existence of strongly interacting massless fermion quasi-particles is particularly significant. My work on graphene focused on showing how lattice gauge theory can be applied to study this material non-perturbatively from first principles.
Image: A picture showing the layout of carbon atoms in the two-dimensional graphene system, taken from 2015 Aspen lectures by Igor Herbut. The colors show the two triangular sub-lattices of graphene: Atoms colored red have three nearest-neighbor atoms colored blue (and vice versa), and are farther away from any other atoms colored red.

A longer discussion of this project will soon be completed in December 2017.
