Phys. Rev. Lett. 102, 053001 (2009) [4 pages]Nearest-Neighbor Detection of Atoms in a 1D Optical Lattice by Fluorescence ImagingReceived 24 July 2008; published 5 February 2009 We overcome the diffraction limit in fluorescence imaging of neutral atoms in a sparsely filled one-dimensional optical lattice. At a periodicity of 433 nm, we reliably infer the separation of two atoms down to nearest neighbors. We observe light induced losses of atoms occupying the same lattice site, while for atoms in adjacent lattice sites, no losses due to light induced interactions occur. Our method points towards characterization of correlated quantum states in optical lattice systems with filling factors of up to one atom per lattice site. © 2009 The American Physical Society URL:
