  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>Muonic hydrogen
    is an exotic atom where a muon instead of an electron is bound to a proton. The
    comparably high mass of the muon (≈ 207 · <jats:italic>m<jats:sub>e</jats:sub>\r\n
    \                 </jats:italic>) has two important effects, (i) the reduced mass
    of the system becomes more important, and (ii) the muon is localized much closer
    to the nucleus. Thus, muonic hydrogen is not only excellently suitable for evaluating
    highly precise quantum electrodynamic (QED) calculations, but may also be used
    for assessing new approaches including finite nuclear size (FNS) effects to evaluate
    the proton structure and improve calculation schemes for the hyperfine splittings
    of many-particle systems, as e.g. to be implemented in density functional theory
    (DFT) software packages. Here, starting from Dirac’s equation we calculate the
    relativistic hyperfine splitting of the ground state and several excited states
    of muonic hydrogen analytically for different charge and magnetization models.
    The FNS related hyperfine shifts are compared with the differences between QED
    calculations and experimental measurements. This comparison also allows to unravel
    the role of the reduced mass, which is on one hand crucial in case of muonic atoms,
    but on the other hand is by no means well defined in relativistic quantum mechanics.</jats:p>"

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>Fostering digital
    competencies is an important aspect of pre-service teacher education. However,
    for physics, there is a lack of systematically surveyed and evidence-based seminars
    that specifically take into account relevant research findings. Thus, we developed
    a research-based seminar on the effective use of digital media in physics classrooms
    and investigated its effects on pre-service teachers (PSTs) professional competencies
    in a mixed-methods design. Our quantitative analyses of different competence components
    surveyed in a pre-post-design indicate that the seminar leads to an increase in
    motivation to use digital media in the physics classroom. Nevertheless, no significant
    increase in digital-media PCK was found, which could be due to the small sample.
    The seminar design, however, was predominantly evaluated positively by experts
    and PSTs in guided interviews. Based on the results, it is planned to further
    refine the original seminar using a Design-Based Research approach.</jats:p>"

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>Theoretical spectroscopy
    based on double perturbation theory is typically challenged by systems with large
    orbital hyperfine splitting. Therefore, we here derive a rigorous, non-perturbative
    scheme starting from Dirac’s equation which allows to calculate the contribution
    of the orbital HFI for complex structures including heavy atoms with strong spin-orbit
    coupling (SOC). Using the PAW formalism, the method has been implemented in the
    software package Quantum ESPRESSO. We show that the ‘orbital part’ actually scales
    with SOC strength if orbital quenching is hindered by low local symmetry, i.e.
    in case of dimers or atoms at surfaces. This holds true in particular when the
    unpaired electron is localized in quasi-atomic <jats:italic>p</jats:italic>-like
    orbitals. Here, the orbital part is by far not negligible, but becomes dominant
    by surpassing the dipolar contribution by a factor of five.</jats:p>"

  text: Curvature scale-space (CSS) analysis is an important technique for contour-based
    object recognition in digital images. To compute the CSS for a given contour,
    it is systematically convolved (smoothed) with Gaussians with increasing standard
    deviation. The convolutions are computationally expensive, especially for large
    and high resolution contours, but can be approximated using box filtering (also
    known as mean and average filtering). Together with running sums, the convolutions
    can be accelerated by 2–3 magnitudes without significant loss of precision. Nonetheless,
    box filtering has not been systematically investigated in connection with CSS
    computation. In this work, we present a theoretical and experimental analysis
    of different box-filtering techniques in this context and conclude which is the
    most efficient implementation. Based on this, the CSS of a contour can be computed
    in real time with high precision.

  text: We study a single quantum dot molecule doped with one electron in the presence
    of electron-phonon coupling. Both diagonal and off-diagonal interactions representing
    real and virtual processes with acoustic phonons via deformation potential and
    piezoelectric coupling are taken into account. We employ a non-perturbative quantum
    kinetic theory and show that the phonon-mediated relaxation is dominated by an
    electron tunneling on a picosecond time scale.A dependence of the relaxation on
    the temperature and the strength of the tunneling coupling is analyzed.

  text: Growth of GaN on Si(111) potentially enables cost efficient manufacturing
    of optoelectronic devices due to the possibility of using cheap large area substrates.
    However, GaN layers grown on Si(111) substrates suffer from high tensile stress
    that can lead to cracking at layer thicknesses exceeding 1 μm. Another challenge
    is the high dislocation density of GaN layers grown on Si(111) which is detrimental
    to device performance. In this paper we show that a step graded AlGaN buffer layer
    can compensate tensile stress, avoiding cracking, and at the same time reduce
    the dislocation density. An additional SiNx interlayer in the GaN layer is shown
    to further reduce the dislocation density down to the high 108 /cm². Weak beam
    dark field TEM was used to study the dislocation reduction in cross sectional
    samples and for comparison of the step graded AlGaN buffer layer structure to
    a continuously graded one. STEM ADF was used to determine the exact location of
    dislocation bending with respect to the position of the interface.
