Query: Sauter-Schwinger like tunneling in tilted Bose-Hubbard lattices in the
  Mott phase   We study the Mott phase of the Bose-Hubbard model on a tilted lattice. On the
(Gutzwiller) mean-field level, the tilt has no effect -- but quantum
fluctuations entail particle-hole pair creation via tunneling. For small
potential gradients (long-wavelength limit), we derive a quantitative analogy
to the Sauter-Schwinger effect, i.e., electron-positron pair creation out of
the vacuum by an electric field. For large tilts, we obtain resonant tunneling
related to Bloch oscillations.
