Controlled Antiadiabatic Crossing of Quantum Phase Transitions — Patrick Doria, Tommaso Calarco, and •Simone Montangero — Ulm University, Ulm, Germany

A control strategy that can be applied to a vast range of non integrable one dimensional systems is introduced and applied to the 1D Mott Insulator-Superfluid quantum phase transition recently demonstrated in cold atoms in optical lattice experiments. We present an optimal pulse to speed up of about an order of magnitude the experimental setup of T.Stoeferle, et. al., Phys. Rev. Lett. 92, 130403 (2004).
