Abstract
The light-induced adiabatic population transfer of holes from the heavy-hole ( ) to the light-hole ( ) band in p-doped semiconductor quantum wells is investigated theoretically. The exact analog to the population-trapped state (PTS) used in atomic and molecular adiabatic population transfer does not exist in a semiconductor due to the continuum of transition energies and the dynamic light-induced shifts thereof. However, it is found that the population transfer only requires an approximate PTS condition to be fulfilled. As for a possible observation of the effect, the transient creation of a exciton resonance at the expense of the exciton is predicted.
