Shortcut to adiabatic passage in two- and three-level atoms

Phys Rev Lett. 2010 Sep 17;105(12):123003. doi: 10.1103/PhysRevLett.105.123003. Epub 2010 Sep 16.


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 with respect to parameter variations. 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.
