Query: Fast closed-loop optimal control of ultracold atoms in an optical
  lattice   We present experimental evidence of the successful closed-loop optimization
of the dynamics of cold atoms in an optical lattice. We optimize the loading of
an ultracold atomic gas minimizing the excitations in an array of
one-dimensional tubes (3D-1D crossover) and we perform an optimal crossing of
the quantum phase-transition from a Superfluid to a Mott-Insulator in a
three-dimensional lattice. In both cases we enhance the experiment performances
with respect to those obtained via adiabatic dynamics, effectively speeding up
the process by more than a factor three while improving the quality of the
desired transformation.
