Adiabatic Population Transfer with Control Fields

This paper explores the benefit of using time dependent basis sets in the description of adiabatic population transfer between molecular states. Using a time dependent basis set formalism, we develop a counter-diabatic field paradigm that generates adiabatic population transfer for apparently unfavorable conditions. We also describe a time dependent perturbation approach to account for the effect of stochastic dephasing on adiabatic population transfer.
