text: Light-emitting diodes (LEDs) are becoming increasingly important across various
sectors of the lighting industry and are being used more frequently. In the field
of symbolic projection, research is increasingly focusing on implementing light
modulation using energy-efficient, incoherent LEDs rather than lasers. Since light
modulation in micro- and nano-optics is typically achieved through phase modulation,
Finite-Difference Time-Domain (FDTD) simulations are employed for analysis. The
objective of this article is to investigate different approaches for approximating
incoherent monochromatic light sources within FDTD simulations. To this end, two
approaches based on dipole sources are considered, as well as a method involving
plane waves with modulated wavefronts based on Cosine–Fourier functions and a
method based on the superposition of Gaussian beams. These methods are evaluated
in terms of their accuracy using a two-dimensional double-slit configuration and
are compared against a fully incoherent analytical reference.

text: Probing novel properties, arising from twisted interfaces, has traditionally
relied on the stacking of exfoliated two-dimensional materials and the spontaneous
formation of van der Waals bonds. So far, investigations involving intimate covalent
or ionic bonds have not been a focus. Yet, we show here that an established technique,
involving thermocompressional wafer bonding, works well for creating twisted non-van
der Waals interfaces. We have successfully bonded z-cut lithium niobate single
crystals to create ferroelectric oxide interfaces with strong polar discontinuities
and have mapped the associated emergent interfacial conductivity. In some instances,
a dramatic change in microstructure occurs, involving local dipolar switching.
A twist-induced collapse in the capability of the system to effec8tively screen
interfacial bound charge is implied. Importantly, this only occurs around specific
moiré twist angles with sparse coincident lattices and associated short-range
aperiodicity. In quasicrystals, aperiodicity is known to induce pseudo-bandgaps
and we suspect a similar phenomenon here.

text: Continuous flow catalysis utilizing gel-bound organocatalysts within a microfluidic
reactor represents a compelling strategy in the realm of organic synthesis. In
this study, a quinuclidine-based catalytic monomer (QMA) was synthesized to create
polymer gel dots through the process of photopolymerization that serve as a support
for the catalyst. The resulting gel-bound organocatalysts were assembled within
a continuous microfluidic reactor to facilitate the Baylis–Hillman reaction between
various aldehydes and acrylonitrile at a temperature of 50 °C. The conversion
of the product was assessed using 1H NMR spectroscopy as an offline analytical
method over a duration of 8 h. The findings indicated that highly reactive aldehydes
achieved conversion rates exceeding 90%, in contrast to their less reactive counterparts.
Furthermore, these results were juxtaposed with previously published data derived
from alternative synthetic methodologies, revealing that the continuous microfluidic
reactions employing integrated organocatalysts within polymer networks exhibited
significantly higher conversions with reduced reaction times (8 h) at the same
temperature (50 °C). Additionally, the influence of different geometries (round,
triangular, and square) of the gel dots on catalytic activity was investigated,
with round and square gel dots demonstrating slightly superior performance compared
with triangular gel dots, attributed to their increased surface area. Moreover,
an extended reaction period of 6 days was conducted using 4-bromobenzaldehyde
and acrylonitrile, resulting in a conversion rate exceeding 70%, which remained
stable for 5 days before experiencing a slight decline due to product accumulation
on the gel dots.

text: AbstractMetasurface holography offers a powerful approach
for manipulating wavefronts at the nano and micro scale. Extensive research has
been conducted to enhance the multiplexing capacity for diverse wavefronts. However,
the independence of multiplexed channels is fundamentally restricted in techniques
using single‐layer metasurfaces, resulting in unavoidable crosstalk and the need
for post‐filtering of the output wavefronts. Here, a universal wavefront multiplexing
concept is presented based on non‐injective transformation. By employing joint
optimization on two metasurfaces, different channels can be independently designed
without any constraints on the output wavefronts. To validate this approach, ultra‐compact
orbital angular momentum (OAM) sorters are designed. In these experiments, the
output beams from different channels can be independently mapped to 2D positions
with high fineness. In another application of wavefront‐multiplexed holography,
10‐channel multiplexing is experimentally achieved with minimal crosstalk and
without the need for post‐processing. These results demonstrate the independence
between channels enabled by the non‐injective transformation in the method. The
precise wavefront control and high multiplexing capacity underscore its potential
for scalable wavefront manipulation devices.

text: "The degrees of freedom (DoFs) of light determine the maximum number of independent
signal\r\nchannels an optical system can support. However, the polarization DoF
is intrinsically limited to two by\r\northogonality, which causes unavoidable
crosstalk and often forces position multiplexing, where different\r\nchannels
are assigned to distinct spatial locations to suppress crosstalk. This research
introduces a multilayer\r\nsynchronous polarization projection method that fundamentally
increases the DoF for polarization\r\nmultiplexing. The DoF equals twice the number
of projection layers. We experimentally demonstrate six-\r\nchannel polarization
multiplexing holography without position multiplexing. The six-channel multiplexing\r\nresults
indicate that our approach exceeds the conventional polarization multiplexing
method, yielding an\r\naverage 3.79 dB improvement in extinction ratio across
the six channels. Compared with the theoretical\r\nlimit of traditional polarization
multiplexing, our method reduces crosstalk by an average of 6.52 dB across\r\nall
channels in a seven-channel design. The polarization projection method breaks
the DoF limitation\r\nof polarization multiplexing, opening a path toward high-dimensional
photonic information encoding for\r\ncommunication, encryption, and imaging."

text: "\r\n The development of practical sensors for
optical coherence tomography (OCT) with undetected photons requires miniaturization
via integration. To be practical, these sensors must exhibit a large spectral
bandwidth and a high brightness, which are linked to a high axial resolution and
a sufficient signal-to-noise ratio, respectively. Here, we combine these requirements
in a scheme for OCT measurements with undetected photons based on nonlinear\r\n

We investigate the performance benchmarks of the commonly used SU(1,1) scheme
in comparison to an induced-coherence scheme and find that the latter is actually
better suited when implementing measurements with undetected photons in integrated
systems. In both schemes, we perform pump-gain optimization and OCT measurements
with undetected photons with an axial resolution as low as\r\n \r\n 28\r\n

text: "\r\n Precise measurements of both the arrival
time and carrier frequency of light pulses are essential for time–frequency-encoded
quantum technologies. Quantum mechanics, however, imposes fundamental limits on
the simultaneous determination of these quantities. In this work, we derive and
experimentally verify the quantum uncertainty bounds governing joint time–frequency
measurements. We show that when detection is restricted to finite time windows,
the problem is naturally described by a quantum rotor, rendering the commonly
used Heisenberg uncertainty relation inapplicable. We further propose an optimal
detection scheme that saturates these fundamental limits. By sampling the\r\n
\ Q\r\n -function,
we demonstrate the reconstruction of the Wigner function beyond the harmonic oscillator.
Using an experimental implementation based on a quantum pulse gate, we confirm
that the proposed scheme approaches the ultimate quantum limit for simultaneous
time–frequency measurements. These results provide a framework for joint time–frequency
detection with direct implications for precision measurements and quantum information
processing.\r\n "

text: Superconducting nanowire single-photon detectors (SNSPDs) can enable
photon-number resolution (PNR) based on accurate measurements of the detector’s
response time to few-photon optical pulses. In this work, we investigate the impact
of the optical pulse shape and duration on the accuracy of this method. We find
that Gaussian temporal pulse shapes yield cleaner arrival-time histograms and,
thus, more accurate PNR, compared to bandpass-filtered pulses of equal bandwidth.
For low system jitter and an optical pulse duration comparable to the other jitter
contributions, photon numbers can be discriminated in our system with a commercial
SNSPD. At 60 ps optical pulse duration, photon-number discrimination is significantly
reduced. Furthermore, we highlight the importance of using the correct arrival-time
histogram model when analyzing photon-number assignment. Using exponentially modified
Gaussian distributions, instead of the commonly used Gaussian distributions, we
can more accurately determine photon-number misidentification probabilities. Finally,
we reconstruct the positive operator-valued measures of the detector, revealing
sharp features that indicate the intrinsic PNR capabilities.

The experiment is based on pulsed frequency bins measured with a multioutput quantum
pulse gate, which can perform projective measurements on a complete high-dimensional
basis in the time-frequency domain. Our results fit the theoretical predictions:
the bound on the sum of the entropies is never violated and is saturated by the
states that minimize the uncertainty relations.\r\n "

text: Metasurfaces are powerful tools for manipulating light using small structures
on the nanoscale. In most metasurfaces, near-field couplings are treated as being
unfavorable perturbations. Here, we experimentally investigate a structure consisting
of sinusoidally modulated silicon waveguides where near-field coupling of local
resonances leads to negative coupling, i.e., a negative coupling constant. This
gives rise to wave-vector-dependent eigenstates of elliptical, linear, and circular
polarizations. In particular, fully circular polarization states are not only
present at a single point in momentum space (k-space) but also along a line. This
circular polarization line, as well as a linear polarization line, emanates from
a polarization degeneracy at the Dirac point. We experimentally validate the existence
of these eigenstates and demonstrate the energy-, polarization-, and wave vector
dependence of this metasurface as well as its sensitivity to fabrication tolerances.
By tuning the incident k-vector, certain polarization-energy eigenstates are strongly
reflected, allowing for uses in angle-tunable polarization filters and light sources.

text: "Abstract\r\n The present study
explored the role of first-year physics students’ sense of belonging to physics
and how it relates to their learning progression in higher education-level physics.
Conducted at Paderborn University, this study examined how students’ sense of
belonging to physics influences their academic outcomes in an introductory experimental
physics course. Additionally, we investigated how physics students’ engagement
in the Physiktreff—a holistic support program for first-year physics students
to help them cope with academic and social challenges during their studies—impacts
the development of their sense of belonging to physics over time. Our findings
indicated that students with a stronger sense of belonging to physics performed
better academically. Moreover, students who actively participated in the support
program experienced a positive shift in their sense of belonging to physics. However,
our findings also revealed that physics students with a higher initial sense of
belonging to physics tended to experience a decline in their sense of belonging
to physics during their first semester. These results underscore the importance
of fostering a sense of belonging to physics within higher education, particularly
during the introductory phase of students’ studies.

text: Das Fachdidaktische Wissen (FDW) zählt zu den zentralen Elementen des Professionswissens
(angehender) Lehrkräfte und seine Relevanz ist sowohl theoretisch angenommen als
auch empirisch belegt. In der fachdidaktischen Forschung liegt daher bereits seit
längerem ein Fokus auf der Analyse des FDW, wobei mittlerweile vor allem Auswirkungen
auf die Handlungsqualität und auf Lernergebnisse in den Blick genommen werden.
Nach wie vor stellt aber auch die empirisch fundierte inhaltliche Beschreibung
des FDW sowie der Transfer entwickelter FDW-Testverfahren auf Basis von Testinstrumenten
mit offenem Antwortformat in die Ausbildungspraxis ein Forschungsdesiderat dar.
In diesem Dissertationsprojekt werden daher auf Basis eines Datensatzes von 846
Bearbeitungen eines FDW-Testinstruments im Fach Physik (1) projektübergreifende
FDW-Kompetenzniveaus auf Basis von Item-Response-Modellierungen exploriert, (2)
nicht-hierarchische FDW-Kompetenzprofile auf Basis von (probabilistischen) Cluster-
und Textanalysen beschrieben und (3) ein vollständig automatisiertes FDW-Assessment-System
auf Basis von Machine Learning entwickelt. Dabei wurden insbesondere kognitive
Anforderungskategorien als Subskalen des verwendeten Testinstruments betrachtet.
Das Assessment-System wurde dabei auf Basis dieser und weiterer Subskalen sowie
anhand der Zuordnung von Proband:innen zu den Kompetenzprofilen evaluiert und
zeigte sowohl relativ zur Interrater-Übereinstimmung als auch absolut betrachtet
hohe Performanzwerte.

text: Pedagogical Content Knowledge (PCK) is one of the central elements of the
professional knowledge of (prospective) teachers. Its relevance is theoretically
established and empirically shown multiple times. PCK has therefore been analyzed
continuously in education research, currently with a particular emphasis on its
impact on the quality of teaching and directly on learning outcomes. However,
there is still a lack of detailed empirically backed descriptions of the intricacies
of PCK and of methodologies for translating developed PCK assessment procedures
based on open-ended questionnaires into educational practice. In this dissertation
project, therefore, three objectives are pursued, based on a dataset of 846 responses
to a physics PCK test instrument. First, cross-project PCK competency levels are
explored based on item response modeling. Second, non-hierarchical PCK competency
profiles are described based on (probabilistic) cluster and text analyses. Third,
a fully automated FDW assessment system based on Machine Learning is developed.
In particular, cognitive requirement categories were considered as subscales of
the test instrument used. The assessment system was evaluated based on these and
other subscales, as well as the assignment of respondents to the competency profiles,
and demonstrated high performance values both in relation to inter-rater agreement
and in absolute terms.
