For specific oblique excitation by semi-guided waves at sufficiently high angles of incidence, the idealized structures do not exhibit any radiative losses, such that reflectance and transmittance for the single port mode add strictly up to one. We consider a series of symmetric, fully and partly etched finite gratings, for parameters found in integrated silicon photonics. These can act as spectral filters with a reasonably flattop response. Apodization can lead to more box shaped reflectance and transmittance spectra. Together with a narrowband Fabry–Perot filter, these configurations are characterized by reflection bands, or transmittance peaks, with widths that span three orders of magnitude. author: - first_name: Manfred full_name: Hammer, Manfred id: '48077' last_name: Hammer orcid: 0000-0002-6331-9348 - first_name: Henna full_name: Farheen, Henna last_name: Farheen - first_name: Jens full_name: Förstner, Jens id: '158' last_name: Förstner orcid: 0000-0001-7059-9862 citation: ama: Hammer M, Farheen H, Förstner J.

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. article_number: '1241909' author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: M. full_name: Stein, M. last_name: Stein - first_name: F. full_name: Schäfer, F. last_name: Schäfer - first_name: D. full_name: Anders, D. last_name: Anders - first_name: J.

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. article_number: 124190G author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: C. full_name: Ngo, C. last_name: Ngo - first_name: S. full_name: Priyadarshi, S. last_name: Priyadarshi - first_name: H.

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." article_type: original author: - first_name: Jeannette full_name: Brosig-Koch, Jeannette last_name: Brosig-Koch - first_name: Burkhard full_name: Hehenkamp, Burkhard id: '37339' last_name: Hehenkamp - first_name: Johanna full_name: Kokot, Johanna last_name: Kokot citation: ama: Brosig-Koch J, Hehenkamp B, Kokot J.

A theory and a laboratory experiment on the relevance of patient characteristics type: journal_article user_id: '37339' year: '2023' ... --- _id: '44093' abstract: - lang: eng 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. author: - first_name: Burkhard full_name: Hehenkamp, Burkhard id: '37339' last_name: Hehenkamp - first_name: Oddvar M. full_name: Kaarbøe, Oddvar M. last_name: Kaarbøe citation: ama: Hehenkamp B, Kaarbøe OM.

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. article_type: original author: - first_name: David full_name: Hähnel, David last_name: Hähnel - first_name: Christian full_name: Golla, Christian last_name: Golla - first_name: Maximilian full_name: Albert, Maximilian last_name: Albert - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Viktor full_name: Myroshnychenko, Viktor id: '46371' last_name: Myroshnychenko - first_name: Jens full_name: Förstner, Jens id: '158' last_name: Förstner orcid: 0000-0001-7059-9862 - first_name: Cedrik full_name: Meier, Cedrik id: '20798' last_name: Meier orcid: https://orcid.org/0000-0002-3787-3572 citation: ama: 'Hähnel D, Golla C, Albert M, et al.
