Abstract
We apply the tools of adiabatic Floquet theory to study the control of population transfer and tunneling processes by strong laser pulses. We show how tunneling can be enhanced by intermediate resonant levels by choosing appropriate pulse parameters. We obtain complete tunneling in times that are much shorter than the bare tunneling time or the times obtained without intermediate levels.Keywords
