Title: Two-dimensional superexchange-mediated magnetization dynamics in an optical lattice.
Authors: Brown, R. C., Wyllie, R., Koller, S. B., Goldschmidt, E. A., Foss-Feig, M., Porto, J. V.

Subjects: Magnetization, Optical lattices, Bosons, Magnetic resonance, Quantum tunneling
Abstract: The article examines nonequilibrium magnetization dynamics in two-dimensional systems by loading bosons into a spin-dependent optical lattice. It states the lattice is used to control resonance conditions for superexchange and tunneling. It comments that relaxation dynamics were observed to be governed by two well-separated rates that scaled with parameters associated with tunneling and superexchange. It suggests the experiment will work as a benchmark on future theoretical work.
