  text: "This thesis studies three topics in quantum computation and information:
    The approximability of quantum problems, quantum proof systems, and non-classical
    correlations in quantum systems. \r\n\r\nIn the first area, we demonstrate a polynomial-time
    (classical) approximation algorithm for dense instances of the canonical QMA-complete
    quantum constraint satisfaction problem, the local Hamiltonian problem. In the
    opposite direction, we next introduce a quantum generalization of the polynomial-time
    hierarchy, and define problems which we prove are not only complete for the second
    level of this hierarchy, but are in fact hard to approximate. \r\n\r\nIn the second
    area, we study variants of the interesting and stubbornly open question of whether
    a quantum proof system with multiple unentangled quantum provers is equal in expressive
    power to a proof system with a single quantum prover. Our results concern classes
    such as BellQMA(poly), and include a novel proof of perfect parallel repetition
    for SepQMA(m) based on cone programming duality. \r\n\r\nIn the third area, we
    study non-classical quantum correlations beyond entanglement, often dubbed \"non-classicality\".
    Among our results are two novel schemes for quantifying non-classicality: The
    first proposes the new paradigm of exploiting local unitary operations to study
    non-classical correlations, and the second introduces a protocol through which
    non-classical correlations in a starting system can be \"activated\" into distillable
    entanglement with an ancilla system. \r\n\r\nAn introduction to all required linear
    algebra and quantum mechanics is included."

  text: We study three variants of multi-prover quantum Merlin-Arthur proof systems.
    We first show that the class of problems that can be efficiently verified using
    polynomially many quantum proofs, each of logarithmic-size, is exactly MQA (also
    known as QCMA), the class of problems which can be efficiently verified via a
    classical proof and a quantum verifier. We then study the class BellQMA(poly),
    characterized by a verifier who first applies unentangled, nonadaptive measurements
    to each of the polynomially many proofs, followed by an arbitrary but efficient
    quantum verification circuit on the resulting measurement outcomes. We show that
    if the number of outcomes per nonadaptive measurement is a polynomially-bounded
    function, then the expressive power of the proof system is exactly QMA. Finally,
    we study a class equivalent to QMA(m), denoted SepQMA(m), where the verifier's
    measurement operator corresponding to outcome "accept" is a fully separable operator
    across the m quantum proofs. Using cone programming duality, we give an alternate
    proof of a result of Harrow and Montanaro [FOCS, pp. 633--642 (2010)] that shows
    a perfect parallel repetition theorem for SepQMA(m) for any m.

  text: We demonstrate that trapping of dispersive waves between two optical solitons
    takes place when resonant scattering of the waves on the solitons leads to nearly
    perfect reflections. The momentum transfer from the radiation to solitons results
    in their mutual attraction and a subsequent collision. The spectrum of the trapped
    radiation can either expand or shrink in the course of the propagation, which
    is controlled by arranging either collision or separation of the solitons.

  text: The frequency-dependent dielectric function and the second-order polarizability
    tensor of ferroelectric LiNbO3 are calculated from first principles. The calculations
    are based on the electronic structure obtained from density-functional theory.
    The subsequent application of the GW approximation to account for quasiparticle
    effects and the solution of the Bethe-Salpeter equation for the stoichiometric
    material yield a dielectric function that slightly overestimates the absorption
    onset and the oscillator strength in comparison with experimental measurements.
    Calculations at the level of the independent-particle approximation indicate that
    these deficiencies are, at least, partially related to the neglect of intrinsic
    defects typical for the congruent material. The second-order polarizability calculated
    within the independent-particle approximation predicts strong nonlinear coefficients
    for photon energies above 1.5 eV. The comparison with measured data suggests that
    the inclusion of self-energy effects in the nonlinear optical response leads to
    a better agreement with experiments. The intrinsic defects of congruent samples
    reduce the optical nonlinearities, in particular, for the 21 and 31 tensor components,
    further improving the agreement between experiments and theory.

  text: We investigate the band dispersion and relevant electronic properties of rubrene
    single crystals within the GW approximation. Due to the self-energy correction,
    the dispersion of the highest occupied molecular orbital (HOMO) band increases
    by 0.10 eV compared to the dispersion of the Kohn-Sham eigenvalues within the
    generalized gradient approximation, and the effective hole mass consequently decreases.
    The resulting value of 0.90 times the electron rest mass along the Γ-Y direction
    in the Brillouin zone is closer to experimental measurements than that obtained
    from density-functional theory. The enhanced bandwidth is explained in terms of
    the intermolecular hybridization of the HOMO(Y) wave function along the stacking
    direction of the molecules. Overall, our results support the bandlike interpretation
    of charge-carrier transport in rubrene.

  text: The GW approximation for the electronic self-energy is an important tool for
    the quantitative prediction of excited states in solids, but its mathematical
    exploration is hampered by the fact that it must, in general, be evaluated numerically
    even for very simple systems. In this paper I describe a nontrivial model consisting
    of two electrons on the surface of a sphere, interacting with the normal long-range
    Coulomb potential, and show that the GW self-energy, in the absence of self-consistency,
    can in fact be derived completely analytically in this case. The resulting expression
    is subsequently used to analyze the convergence of the energy gap between the
    highest occupied and the lowest unoccupied quasiparticle orbital with respect
    to the total number of states included in the spectral summations. The asymptotic
    formula for the truncation error obtained in this way, whose dominant contribution
    is proportional to the cutoff energy to the power −3/2, may be adapted to extrapolate
    energy gaps in other systems.

  text: Modelle Allgemeiner Didaktik sind in der Regel weder empirisch fundiert noch
    ist ihr Verhältnis zum realen Planungshandeln von Lehrerinnen und Lehrern geklärt.
    Theoretische Basis für empirische Studien zur Unterrichtsplanung sind selten allgemeindidaktische
    Modelle, sondern eher psychologische Theorien. Auch die Forschungzu Aufgaben ist
    bislang eher kognitionspsychologisch orientiert. Vor diesem Hintergrund knüpft
    der vorliegende Beitrag an die allgemeindidaktische Aufgabenforschung an. Allerdings
    erwies sich der Begriff der Aufgabe im Laufe des Forschungsprozesses als zu eng
    bzw. voraussetzungsvoll und wurde daher zugunsten des Konzepts der Schüleraktivitäten
    erweitert. Die zentrale Frage der explorativen Studie lautet demnach, wie Lehrerinnen
    und Lehrer Schüleraktivitäten planen. Die Überlegungen wurden dabei mit der Methode
    des Lauten Denkens erfasst und qualitativ inhaltsanalytisch ausgewertet. Erste
    Ergebnisse zeigen, dass Lehrerinnen und Lehrer zwar implizit in ihrer Planung
    einige der Dimensionen berücksichtigen, die mit allgemeindidaktischen Modellen
    in Einklang stehen, dass aber noch ungenügend erforscht wurde, wie Schüleraktivitäten
    in den subjektiven Planungsüberlegungen vorkommen.

  text: "Die Kooperation von Lehrkräften wird als ein zentrales Merkmal „guter\r\nSchulen“
    eingestuft. Gleichwohl sind die zugehörigen Befunde mitunter wi-\r\ndersprüchlich.
    Vor dem Hintergrund eines theoretischen Wirkungsmodells\r\nreferiert der vorliegende
    Beitrag sowohl bestätigende als auch relativierende\r\nErgebnisse im Hinblick
    auf die Bedeutung der Lehrerkooperation für die\r\nSchulleistung, welche ihrerseits
    zunächst als Indikator des Erfolgs kumulati-\r\nver Bildungsprozesse theoretisch
    gefasst wird.\r\nBestätigende Befunde lassen sich etwa im Hinblick auf einen Konsens
    zwi-\r\nschen Lehrkräften bei der Umsetzung des Curriculums, den Lerngelegenhei-\r\nten
    für Lehrkräfte oder den fachdidaktischen Impulsen innerhalb von Kolle-\r\ngien
    ausmachen. Relativierende Hinweise liefern beispielsweise – vor dem\r\nHintergrund
    einer elaborierten Kooperationskultur – die häufig erwartungs-\r\nwidrig schlechten
    Schulleistungen an Gesamtschulen sowie die fehlenden\r\nEffekte der Kooperationspraktiken
    auf das kumulative Kompetenzniveau in\r\nDeutsch und Englisch gemäß der DESI-Studie.\r\nDie
    aufgezeigten Perspektiven für die Forschung beziehen sich u.a. auf eine\r\npräzisere
    Erfassung solcher Faktoren des Unterrichts, die einerseits durch\r\nLehrerkooperation
    verbessert werden können und andererseits in großer\r\nProximität zum Schülerlernen
    stehen, zum Beispiel die kognitive Aktivierung."
