Phys. Rev. A 76, 063602 (2007) [5 pages]Scanning tunneling microscopy for ultracold atomsReceived 23 January 2007; revised 26 June 2007; published 4 December 2007 We propose a versatile experimental probe for cold atomic gases analogous to the scanning tunneling microscope (STM) in condensed matter. This probe uses the coherent coupling of a single particle to the system. Depending on the measurement sequence, our probe allows us to obtain either the local density and spatial density correlations, with a resolution on the nanometer scale, or the single particle correlation function in real time. We discuss applications of this scheme to the various possible phases for a two dimensional Hubbard system of fermions in an optical lattice. © 2007 The American Physical Society URL:
