Abstract in another language
We have analyzed the initial decoherence of strongly confined semiconductor quantum dots by performing four-wave-mixing experiments and comparing with theory. The measurements are in quantitative agreement with analytical results accounting for the pure dephasing induced by acoustic phonons. The experiments confirm the recent prediction of an unusual nonmonotonous temperature dependence of the initial decoherence time.
