Optical Flux Lattices for Ultracold Atomic Gases

Author(s): N. R. CooperWe show that simple laser configurations can give rise to “optical flux lattices,” in which optically dressed atoms experience a periodic effective magnetic flux with high mean density. These potentials lead to narrow energy bands with nonzero Chern numbers. Optical flux lattices will greatly facili... [Phys. Rev. Lett. 106, 175301] Published Mon Apr 25, 2011
