Bloch oscillations of strongly interacting Bose atoms
  We analyse Bloch oscillations (i.e., oscillations induced by a static force) of strongly interacting Bose atoms {\em beyond} the hard-core bosons model. It is shown that residual interactions between the atoms modulate Bloch oscillations, where the type of modulations depends on the magnitude of the static force.
