Abstract

We have directly observed spin-dependent transport of single cesium atoms in a 1D optical lattice. A superposition of two circularly polarized standing waves is generated from two counter propagating, linearly-polarized laser beams. Rotation of one of the polarizations by π causes displacement of the σ⁺ and the σ^--lattices by one lattice site. Unidirectional transport over several lattice sites is achieved by rotating the polarization back and forth and flipping the spin after each transport step. We have analyzed the transport efficiency over 10 and more lattice sites, and we discuss and quantify the relevant error sources.
