Excursions Through Flatland: Braiding Interactions of Anyons

Speaker: Gavin Brennen, Macquarie University, Sydney

Talk Title: Excursions Through Flatland: Braiding Interactions of Anyons

Abstract: In systems with physics constrained to two dimensions, point like particles named anyons can occur which have more general exchange statistics than bosons or fermions. While these particles emerge as quasiparticle excitions from strongly correlated ``vacuum" states, they are long- lived and robust to perturbations. I will describe the transport properties of anyons in the presence of ordered and random topological environments. Using both a discrete time quantum walk model and a continuous time Hubbard model we find very distinct behaviours for Abelian and non-Abelian anyons which could be observed in experiment.

Biography: Gavin Brennen grew up in Alaska and did his studies at the U. of Alaska and U. of New Mexico receiving his PhD in theoretical physics from UNM in 2001. Afterward he worked as a research fellow at U. Maryland/NIST Gaithersburg, MD and as senior scientist at the Institute for Quantum Optics and Quantum Information, Innsbruck Austria. In 2007 he was appointed Assoc. Prof. at Macquarie University, Sydney where he and his group work on quantum information theory, coherent control of atomic/molecular/optical systems, and topological phases.
