Edge transport in 2D cold atom optical lattices. Scarola, V., W. & Das Sarma, S. Physical Review Letters, 98(21):210403, 2007. Paper Website doi abstract bibtex We theoretically study the observable response of edge currents in two dimensional cold atom optical lattices. As an example we use Gutzwiller mean-field theory to relate persistent edge currents surrounding a Mott insulator in a slowly rotating trapped Bose-Hubbard system to time of flight measurements. We briefly discuss an application, the detection of Chern number using edge currents of a topologically ordered optical lattice insulator.
