text: The nonlinear optical response of quantum well excitons is investigated experimentally
using polarization resolved four wave mixing, optical-pump optical-probe, and
optical-pump Terahertz-probe spectroscopy. The four-wave mixing data reveal clear
signatures of coherent biexcitons which concur with straight-forward polarization
selection rules at the Γ point. The type-I samples show the well-established time-domain
beating signatures in the transients as well as the corresponding spectral signatures
clearly. The latter are also present in type-II samples; however, the smaller
exciton and biexciton binding energies in these structures infer longer beating
times which, in turn, are accompanied by faster dephasing of the type-II exciton
coherences. Furthermore, the THz absorption following spectrally narrow, picosecond
excitation at energies in the vicinity of the 1s exciton resonance are discussed.
Here, the optical signatures yield the well-established redshifts and blueshifts
for the appropriate polarization geometries in type-I quantum well samples also
termed “AC Stark Effect”. The THz probe reveals intriguing spectral features which
can be ascribed to coherent negative absorption following an excitation into a
virtual state for an excitation below the 1s exciton resonance. Furthermore, the
scattering and ionization of excitons is discussed for several excitation geometries
yielding control rules for elastic and inelastic quasiparticle collisions.

text: The nonlinear optical response of quantum well excitons excited by optical
fields is analyzed by numerical solutions of the semiconductor Bloch equations.
Differential absorption spectra are computed for resonant pumping at the exciton
resonance and the dependence of the absorption changes on the polarization directions
of the pump and probe pulses is investigated. Coherent biexcitonic many-body correlations
are included in our approach up to third-order in the optical fields. Results
are presented for spatially-direct type-I and spatiallyindirect type-II quantum
well systems. Due to the spatial inhomogeneity, in type-II structures a finite
coupling between excitons of opposite spins exists already on the Hartree-Fock
level and contributes to the absorption changes for the case of opposite circularly
polarized pump and probe pulses.

text: High harmonic generation (HHG) from solids shows great application
prospects in compact short-wavelength light sources and as a tool for imaging
the dynamics in crystals with subnanometer spatial and attosecond temporal resolution.
However, the underlying collision dynamics behind solid HHG is still intensively
debated and no direct mapping relationship between the collision dynamics with
band structure has been built. Here, we show that the electron and its associated
hole can be elastically scattered by neighboring atoms when their wavelength approaches
the atomic size. We reveal that the elastic scattering of electron/hole from neighboring
atoms can dramatically influence the electron recombination with its left-behind
hole, which turns out to be the fundamental reason for the anisotropic interband
HHG observed recently in bulk crystals. Our findings link the electron/hole backward
scattering with Van Hove singularities and forward scattering with critical lines
in the band structure and thus build a clear mapping between the band structure
and the harmonic spectrum. Our work provides a unifying picture for several seemingly
unrelated experimental observations and theoretical predictions, including the
anisotropic harmonic emission in MgO, the atomic-like recollision mechanism of
solid HHG, and the delocalization of HHG in ZnO. This strongly improved understanding
will pave the way for controlling the solid-state HHG and visualizing the structure-dependent
electron dynamics in solids.

text: We investigate the transient optical response in high-quality Cd0.88Zn0.12Te
crystals in the regime of slow light propagation on the lower exciton-polariton
branch. Femtosecond photoexcitation leads to very substantial transmission changes
in a ∼10-meV broad spectral range within the transparency window of the unexcited
semiconductor. These nonlinear optical signatures decay on picosecond time scales
governed by carrier thermalization and recombination. The temporal and spectral
dependence indicate the dynamical optical response as arising from excitation-induced
dephasing and perturbed free induction decay. Model simulations for the optical
response taking into account the actual exciton-polariton dispersion and excitation-induced
dephasing of a nonlinearly driven two-level system support this interpretation.
