Query: Sensitive measurement of forces at micron scale using Bloch oscillations
  of ultracold atoms   We show that Bloch oscillations of ultracold fermionic atoms in the periodic
potential of an optical lattice can be used for a sensitive measurement of
forces at the micrometer length scale, e.g. in the vicinity of dielectric
surface. In particular, the proposed approach allows to perform a local and
direct measurement of the Casimir-Polder force which is, for realistic
experimental parameters, as large as 10^-4 gravity.
