Tunable superlattices for correlated topological states

Electrons confined in two dimensions can show qualitatively different behaviors due to nontrivial topology and strong correlation between electrons. In one example, the collective motion of electrons behaves as exotic particles called anyons. These anyons are the fundamental elements to realize topological quantum computation in the future. My proposal will experimentally study the electronic properties of anyons in graphene an atomically thin layer of graphite. In particular, my team will investigate how the crystal lattice influences the formation of anyons and how to make the anyons robust. To achieve this goal, we will utilize nanotechnology tools to create a new type of device featuring tunable artificial lattices made from graphene and other two-dimensional materials.
