Here, we present an experimentally feasible protocol for the probabilistic orthogonalisation of a pair of coherent states, independent of their amplitude and phase. In contrast to unambiguous state discrimination, a successful operation of our protocol is heralded without measuring the states. As such, they remain suitable for further manipulation and the obtained orthogonal states serve as a discretevariable basis. Therefore, our protocol doubles as a simple continuous-to-discrete variable converter, which may find application in hybrid continuous-discrete quantum information processing protocols.</jats:p>}},

In particular, photoinduced phase transitions (PIPTs) in solids provide a test case for how forces, and the resulting atomic motion along a reaction coordinate, originate from a nonequilibrium population of excited electronic states. Using femtosecond photoemission, we obtain access to the transient electronic structure during an ultrafast PIPT in a model system: indium nanowires on a silicon(111) surface. We uncover a detailed reaction pathway, allowing a direct comparison with the dynamics predicted by ab initio simulations. This further reveals the crucial role played by localized photoholes in shaping the potential energy landscape and enables a combined momentum- and real-space description of PIPTs, including the ultrafast formation of chemical bonds.</jats:p>}},

Auch angehende Physiklehrkräfte sollten schon in der ersten Ausbildungsphase auf diese Anforderungen vorbereitet werden. Hierzu müssen sie Kompetenzen insbesondere zum Einsatz spezifischer digitaler Medien für das Lehren und Lernen von Physik erwerben. Um dies zu ermöglichen, wurde an der Universität Paderborn das Seminarkonzept MORPH entwickeln und erprobt. Dabei handelt es sich um einen fachdidaktischen Projektkurs, der den Nutzen digitaler Werkzeuge für das naturwissenschaftliche Arbeiten betont. Als zentrale Lernaktivitäten nutzen die Teilnehmenden digitale Werkzeuge, um physikalische Alltagsphänomene experimentell zu analysieren und zu modellieren. Neben einer Beschreibung didaktischer Hintergründe des Konzepts und einer konkreten Umsetzung berichtet der Beitrag zudem die Ergebnisse einer Evaluation der ersten beiden Erprobungen. Dabei stellte sich heraus, dass die Studierenden zwar die angestrebten Fähigkeiten zum Umgang mit digitalen Werkzeugen erwerben, sie aber für eine Nutzung digitaler Medien in ihrer späteren Unterrichtstätigkeit eher weniger motiviert werden konnten.}},

  abstract     = {{In recent years, Raman spectroscopy has been used to visualize and analyze ferroelectric domain structures.
The technique makes use of the fact that the intensity or frequency of certain phonons is strongly influenced
by the presence of domain walls. Although the method is used frequently, the underlying mechanism responsible
for the changes in the spectra is not fully understood. This inhibits deeper analysis of domain structures based
on this method. Two different models have been proposed. However, neither model completely explains all
observations. In this work, we have systematically investigated domain walls in different scattering geometries
with Raman spectroscopy in the common ferroelectric materials used in integrated optics, i.e., KTiOPO4,
LiNbO3, and LiTaO3. Based on the two models, we can demonstrate that the observed contrast for domain
walls is in fact based on two different effects. We can identify on the one hand microscopic changes at the
domain wall, e.g., strain and electric fields, and on the other hand a macroscopic change of selection rules at the
domain wall. While the macroscopic relaxation of selection rules can be explained by the directional dispersion
of the phonons in agreement with previous propositions, the microscopic changes can be explained qualitatively
in terms of a simplified atomistic model.}},

  abstract     = {{In the context of ferroelectrics spatially resolved Raman spectroscopy is a powerful tool to investigate stoichiometry, defects or the ferroelectric properties, as well as to visualize domain structures or waveguides. Using Raman spectroscopy for investigations requires a throughout understanding of the spectra and underlying mechanisms. For example, in the context of the common nonlinear materials, lithium niobate and potassium titanyl phosphate, no comprehensive understanding of the Raman spectra of the bulk materials is available, while the underlying mechanism of the domain wall contrast in Raman spectroscopy is not well understood. In this work, questions like these have been addressed in terms of systematic experimental investigations in close cooperation with density functional theory. In particular, it was possible to present a complete assignment of all phonons in the lithium niobate system, which serves as the basis for the understanding of the domain wall spectrum. Here, the domain wall spectrum can be explained with regard to microscopic structural effects, such as strains and electric fields, as well as a macroscopic change of selections rules. Both mechanisms are likewise present in the domain wall spectrum, while being present at different length scales. In the context of potassium titanyl phosphate the first throughout Raman investigations of domain structure, waveguides and periodically poled waveguides are presented. In the context of Rb-exchanged waveguides the change in stoichiometry, but also effects of strain are detected. Here, the Raman analysis provides a method to evaluate these effects.}},
