  text: '<jats:title>Abstract</jats:title><jats:p>Recent approaches to Explainable
    AI (XAI) promise to satisfy diverse user expectations by allowing them to steer
    the interaction in order to elicit content relevant to them. However, little is
    known about how and to what extent the explainee takes part actively in the process
    of explaining. To tackle this empirical gap, we exploratively examined naturally
    occurring everyday explanations in doctor–patient interactions (<jats:italic>N</jats:italic> = 11).
    Following the social design of XAI, we view explanations as emerging in interactions:
    first, we identified the verbal behavior of both the explainer and the explainee
    in the sequential context, which we could assign to phases that were either monological
    or dialogical; second, we investigated in particular who was responsible for the
    initiation of the different phases. Finally, we took a closer look at the global
    conversational structure of explanations by applying a context-sensitive model
    of organizational jobs, thus adding a third layer of analysis. Results show that
    in our small sample of conversational explanations, both monological and dialogical
    phases varied in their length, timing of occurrence (at the early or later stages
    of the interaction) and their initiation (by the explainer or the explainee).
    They alternated several times in the course of the interaction. However, we also
    found some patterns suggesting that all interactions started with a monological
    phase initiated by the explainer. Both conversational partners contributed to
    the core organizational job that constitutes an explanation. We interpret the
    results as an indication for naturally occurring everyday explanations in doctor–patient
    interactions to be co-constructed on three levels of linguistic description: (1)
    by switching back and forth between monological to dialogical phases that (2) can
    be initiated by both partners and (3) by the mutual accomplishment and thus responsibility
    for an explanation’s core job that is crucial for the success of the explanation.
    Because of the explorative nature of our study, these results need to be investigated
    (a) with a larger sample and (b) in other contexts. However, our results suggest
    that future designs of artificial explainable systems should design the explanatory
    dialogue in such a way that it includes monological and dialogical phases that
    can be initiated not only by the explainer but also by the explainee, as both
    contribute to the core job of explicating procedural, clausal, or conceptual relations
    in explanations.</jats:p>'

  text: 'Hole polarons and defect-bound exciton polarons in lithium niobate are investigated
    by means of density-functional theory, where the localization of the holes is
    achieved by applying the +U approach to the oxygen 2p orbitals. We find three
    principal configurations of hole polarons: (i) self-trapped holes localized at
    displaced regular oxygen atoms and (ii) two other configurations bound to a lithium
    vacancy either at a threefold coordinated oxygen atom above or at a two-fold coordinated
    oxygen atom below the defect. The latter is the most stable and is in excellent
    quantitative agreement with measured g factors from electron paramagnetic resonance.
    Due to the absence of mid-gap states, none of these hole polarons can explain
    the broad optical absorption centered between 2.5 and 2.8 eV that is observed
    in transient absorption spectroscopy, but such states appear if a free electron
    polaron is trapped at the same lithium vacancy as the bound hole polaron, resulting
    in an exciton polaron. The dielectric function calculated by solving the Bethe–Salpeter
    equation indeed yields an optical peak at 2.6 eV in agreement with the two-photon
    experiments. The coexistence of hole and exciton polarons, which are simultaneously
    created in optical excitations, thus satisfactorily explains the reported experimental
    data.'

  text: Lithium niobate (LiNbO3), a material frequently used in optical applications,
    hosts different kinds of polarons that significantly affect many of its physical
    properties. In this study, a variety of electron polarons, namely free, bound,
    and bipolarons, are analyzed using first-principles calculations. We perform a
    full structural optimization based on density-functional theory for selected intrinsic
    defects with special attention to the role of symmetry-breaking distortions that
    lower the total energy. The cations hosting the various polarons relax to a different
    degree, with a larger relaxation corresponding to a larger gap between the defect
    level and the conduction-band edge. The projected density of states reveals that
    the polaron states are formerly empty Nb 4d states lowered into the band gap.
    Optical absorption spectra are derived within the independent-particle approximation,
    corrected by the GW approximation that yields a wider band gap and by including
    excitonic effects within the Bethe-Salpeter equation. Comparing the calculated
    spectra with the density of states, we find that the defect peak observed in the
    optical absorption stems from transitions between the defect level and a continuum
    of empty Nb 4d states. Signatures of polarons are further analyzed in the reflectivity
    and other experimentally measurable optical coefficients.

  text: <jats:p>Multimode integrated interferometers have great potential for both
    spectral engineering and metrological applications. However, the material dispersion
    of integrated platforms constitutes an obstacle that limits the performance and
    precision of such interferometers. At the same time, two-colour nonlinear interferometers
    present an important tool for metrological applications, when measurements in
    a certain frequency range are difficult. In this manuscript, we theoretically
    developed and investigated an integrated multimode two-colour SU(1,1) interferometer
    operating in a supersensitive mode. By ensuring the proper design of the integrated
    platform, we suppressed the dispersion, thereby significantly increasing the visibility
    of the interference pattern. The use of a continuous wave pump laser provided
    the symmetry between the spectral shapes of the signal and idler photons concerning
    half the pump frequency, despite different photon colours. We demonstrate that
    such an interferometer overcomes the classical phase sensitivity limit for wide
    parametric gain ranges, when up to 3×104 photons are generated.</jats:p>

  text: Lithium niobate on insulator (LNOI) has a great potential for photonic integrated
    circuits, providing substantial versatility in design of various integrated components.
    To properly use these components in the implementation of different quantum protocols,
    photons with different properties are required. In this paper, we theoretically
    demonstrate a flexible source of correlated photons built on the LNOI waveguide
    of a special geometry. This source is based on the parametric down-conversion
    (PDC) process, in which the signal and idler photons are generated at the telecom
    wavelength and have different spatial profiles and polarizations, but the same
    group velocities. Distinguishability in polarizations and spatial profiles facilitates
    the routing and manipulating individual photons, while the equality of their group
    velocities leads to the absence of temporal walk-off between photons. We show
    how the spectral properties of the generated photons and the number of their frequency
    modes can be controlled depending on the pump characteristics and the waveguide
    length. Finally, we discuss special regimes, in which narrowband light with strong
    frequency correlations and polarization-entangled Bell states are generated at
    the telecom wavelength.

  text: Quantum walks function as essential means to implement quantum simulators,
    allowing one to study complex and often directly inaccessible quantum processes
    in controllable systems. In this contribution, the notion of a driven Gaussian
    quantum walk is introduced. In contrast to typically considered quantum walks
    in optical settings, we describe the operation of the walk in terms of a nonlinear
    map rather than a unitary operation, e.g., by replacing a beam-splitter-type coin
    with a two-mode squeezer, being a process that is controlled and driven by a pump
    field. This opens previously unattainable possibilities for quantum walks that
    include nonlinear elements as core components of their operation, vastly extending
    their range of applications. A full framework for driven Gaussian quantum walks
    is developed, including methods to dynamically characterize nonlinear, quantum,
    and quantum-nonlinear effects. Moreover, driven Gaussian quantum walks are compared
    with their classically interfering and linear counterparts, which are based on
    classical coherence of light rather than quantum superpositions. In particular,
    the generation and boost of highly multimode entanglement, squeezing, and other
    quantum effects are studied over the duration of the nonlinear walk. Importantly,
    we prove the quantumness of the evolution itself, regardless of the input state.
    A scheme for an experimental realization is proposed. Furthermore, nonlinear properties
    of driven Gaussian quantum walks are explored, such as amplification that leads
    to an ever increasing number of correlated quantum particles, constituting a source
    of new walkers during the walk. Therefore, a concept for quantum walks is proposed
    that leads to—and even produces—directly accessible quantum phenomena, and that
    renders the quantum simulation of nonlinear processes possible.

  text: In this publication a novel method for far-field prediction from magnetic
    Huygens box data based on the boundary element method (BEM) is presented. Two
    examples are considered for the validation of this method. The first example represents
    an electric dipole so that the obtained calculations can be compared to an analytical
    solution. As a second example, a printed circuit board is considered and the calculated
    far-field is compared to a fullwave simulation. In both cases, the calculations
    for different field integral equations are under comparison, and the results indicate
    that the presented method performs very well with a combined field integral equation,
    for the specified problem, when only magnetic Huygens box data is given.
