Shortcut to adiabatic passage in two- and three-level atoms — •Andreas Ruschhaupt — Institut für Theoretische Physik, Leibniz Universität Hannover, Appelstraße 2, 30167 Hannover, Germany

We propose a method to speed up adiabatic passage techniques in two-level and three-level atoms extending to the short-time domain their robustness. It supplements or substitutes the standard laser beam setups with auxiliary pulses that steer the system along the adiabatic path. Compared to other strategies such as composite pulses or the original adiabatic techniques, it provides a fast and robust approach to population control.
