Abstract in another language

A comprehensive analysis of the effect of pure dephasing processes on the linear as well as the nonlinear optical response of quantum dots is presented. The focus is on small dots where it is permissible to consider only the lowest energy states. It turns out that pure dephasing can be studied analytically in this limit. The analysis is based on exact closed form expressions for the linear susceptibility as well as for the nonlinear response to a sequence of delta pulses. The dependences of linear absorption spectra on statically applied fields and on the temperature for different dot sizes are discussed. Exact results are compared with calculations based on the correlation expansion. Four-Wave-Mixing spectra are presented for different temperatures and strength of the inhomogeneous broadening. Good qualitative agreement with experiments is found.
