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: Anomalous currents refer to electronic currents that flow perpendicularly
to the direction of the accelerating electric field. Such anomalous currents can
be generated when Terahertz fields are applied after an optical interband excitation
of GaAs quantum wells. The underlying processes are investigated by numerical
solutions of the semiconductor Bloch equations in the length gauge. Excitonic
effects are included by treating the manybody Coulomb interaction in time-dependent
Hartree-Fock approximation and additionally also carrier-phonon scattering processes
are considered. The band structure and matrix elements are obtained from a 14-band
k · p model within the envelope function approximation. The random phase factors
of the matrix elements that appear due to the separate numerical diagonalization
at each k-point are treated by applying a smooth gauge transformation. We present
the macroscopic Berry curvature and anomalous current transients with and without
excitonic effects. It is demonstrated that the resonant optical excitation of
excitonic resonances can significantly enhance the Berry curvature and the anomalous
currents.

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: "We study how competition between physicians affects the provision of medical
care. In\r\nour theoretical model, physicians are faced with a heterogeneous patient
population, in which patients\r\nsystematically vary with regard to both their
responsiveness to the provided quality of care and their\r\nstate of health. We
test the behavioral predictions derived from this model in a controlled laboratory\r\nexperiment.
In line with the model, we observe that competition significantly improves patient
benefits\r\nas long as patients are able to respond to the quality provided. For
those patients, who are not able\r\nto choose a physician, competition even decreases
the patient benefit compared to a situation without\r\ncompetition. This decrease
is in contrast to our theoretical prediction implying no change in benefits for\r\npassive
patients. Deviations from patient-optimal treatment are highest for passive patients
in need of\r\na low quantity of medical services. With repetition, both, the positive
effects of competition for active\r\npatients as well as the negative effects
of competition for passive patients become more pronounced. Our\r\nresults imply
that competition can not only improve but also worsen patient outcome and that
patients’\r\nresponsiveness to quality is decisive."

text: We consider a model where for-profit providers compete in quality in a price-regulated
market that has been opened to competition, and where the incumbent is located
at the center of the market, facing high costs of relocation. The model is relevant
in markets such as public health care, education and schooling, or postal services.
We find that, when the regulated price is low or intermediate, the entrant strategically
locates towards the corner of the market to keep the incumbent at the low monopoly
quality level. For a high price, the entrant locates at the corner of the market
and both providers implement higher quality compared to a monopoly. In any case,
the entrant implements higher quality than the incumbent provider. Social welfare
is always higher in a duopoly if the cost of quality is low. For higher cost levels
welfare is non-monotonic in the price and it can be optimal to the regulator not
to use its entire budget. Therefore, the welfare effect of entry depends on the
price and the size of the entry cost, and the regulator should condition the decision
to allow entry on an assessment of the entry cost.

text: We present strong enhancement of third harmonic generation in an amorphous
silicon metasurface consisting of elliptical nano resonators. We show that this
enhancement originates from a new type of multi-mode Fano mechanism. These ‘Super-Fano’
resonances are investigated numerically in great detail using full-wave simulations.
The theoretically predicted behavior of the metasurface is experimentally verified
by linear and nonlinear transmission spectroscopy. Moreover, quantitative nonlinear
measurements are performed, in which an absolute conversion efficiency as high
as ηmax ≈ 2.8 × 10−7 a peak power intensity of 1.2 GW cm−2 is found. Compared
to an unpatterned silicon film of the same thickness amplification factors of
up to ~900 are demonstrated. Our results pave the way to exploiting a strong Fano-type
multi-mode coupling in metasurfaces for high THG in potential applications.
