Query: Coherent control of atom dynamics in an optical lattice   On the basis of a simple exactly solvable model we discuss the possibilities
for state preparation and state control of atoms in a periodic optical
potential. In addition to the periodic potential a uniform force with an
arbitrary time dependence is applied. The method is based on a formal
expression for the full evolution operator in the tight-binding limit. This
allows us to describe the dynamics in terms of operator algebra, rather than in
analytical expansions.
