Magnetism in Quantum Gases

Speaker: Prof. Dan Stamper-Kurn, Berkeley University

With quantum gases, one can explore magnetic ordering and dynamics in regimes inaccessible in solid-state systems. For example, in degenerate spinor Bose gases, magnetization of the atomic spin is established along with Bose-Einstein condensation, allowing minute spin-dependent energies to dictate the magnetic ordering of the gas. The extreme isolation of the atomic system allows us to populate the magnetic superfluids with magnetic excitations, and observe their coherent dynamics and eventual re-condensation. A second cold-atom material, in which atoms are confined within the periodic potential of an optical lattice, bears a stronger resemblance to condensed-matter systems. I will present progress to explore the effects of geometric frustration with cold atoms that are confined in a twodimensional kagome optical lattice.
