text: "A microscopic approach is presented to compute nonlinear optical properties
of semiconductor surfaces. The method uses quasiparticle wave functions and dispersions
obtained from ab initio band-structure theory as an input for Bloch equations
which describe the optical properties. Excitonic effects in the linear absorption
spectra of the Si(111)-\r\n(2×1) surface are obtained by integrating equations
of motion. To demonstrate the applicability of the approach for analyzing nonlinear
optical properties, ultrafast light-intensity-dependent absorption changes of
the surface exciton are predicted. The numerical results discuss the optical Stark
effect and spectral oscillations of the surface exciton which can both be observed
in pump-probe experiments."

text: A novel microscopic approach for computing nonlinear optical properties of
semiconductor surfaces is outlined. The linear and nonlinear response of the Si(111)-(2×1)
surface is studied using a combination of ab-initio band-structure theory and
equation of motion technique. The usefulness of the method is shown by reproducing
known excitonic effects in the linear differential reflectivity spectrum. To additionally
demonstrate the applicability of the approach for the nonlinear regime, the nonlinear
optical response in Stark effect configuration is examined.

text: A three-beam configuration is used to investigate the spectrally resolved
wave-mixing signal of a ZnSe single quantum well. The spectrum recorded in direction
2 k2–k1 shows coherent oscillations induced by a delayed third pulse with direction
k3. Intensity and polarization-dependent measurements indicate that the signal
is generated by a combination of four- and six-wave mixing. The origin of the
oscillations can be explained qualitatively by a two-level model. The polarization-dependent
experimental results require the treatment of many-body correlations and are well
explained by microscopic calculations including four-particle correlations up
to fifth order in the fields.

text: The nonlinear optical response of a ZnSe single quantum well is investigated
by spectrally resolving a wave-mixing signal using a three-beam configuration.
A delayed third pulse with direction k3 leads to coherent oscillations in the
spectrum emitted in 2k2–k1. Polarization-dependent measurements highlight the
importance of higher-order Coulomb correlations as the dominant coupling mechanism
between the three pulses. The experimental results are well explained by microscopic
calculations including four-particle correlations up to fifth order in the fields.

text: A phenomenological multi-exciton level scheme is used to calculate the excitonic
differential absorption as measured in pump and probe experiments. Numerical results
are compared to those obtained by a fully microscopic density-matrix theory. For
resonant excitation, optimized parameters yield qualitative agreement, but the
phenomenological approach soon reaches its limit for non-resonant pumping.
