Title: Quantum control of ultracold atoms and molecules
 

Abstract
We will review several time-dependent schemes for controlling the quantum states of ultracold bosons in an optical lattice and for
controlling the orientation of cold molecules. Our calculations are based on the exact solution of the time-dependent Schroedinger equation, using the Floquet formalism. We show that tunneling and localization properties of interacting ultracold atoms in an optical lattice can be controlled by adiabatically turning on a fast oscillatory force even in the presence of disorder. Implications of our findings for larger systems and the possibility of controlling the phase diagram of disordered-interacting bosonic systems
are discussed. We will also discuss the possibility of generating finite momentum using this fast oscillatory force. Finally, we will briefly review recent work on orientation of molecules using ultrafast laser fields.
