text: "The Circular Economy is considered a key approach to addressing resource
scarcity, rising raw material prices, and the need for more resilient value chains.
However, its practical implementation is often hindered by the lack of suitable
and standardized metrics, as well as by high requirements for horizontal and vertical
data integration. This white paper illustrates, through selected Manufacturing-X
projects, how federated data ecosystems can help establish Circular Economy metrics
as an effective management instrument for growth, margin protection, and resilience.\r\nBased
on literature, industrial practice, and demonstrators, Circular Economy metrics
are structured into four groups: overarching assessment approaches, disassembly-related
indicators, lifetime-oriented metrics, and end-of-life and recycling-focused indicators.
Use cases from Construct-X, Decide4ECO, Fluid 4.0, Chem-X, and other Manufacturing-X
initiatives demonstrate the benefits of data-driven approaches for product, component,
and material loops. At the same time, they reveal a current lack of interoperable,
cross-industry standards for both metrics and data models.\r\nThe white paper
concludes that data ecosystems such as Manufacturing-X are a key enabler for scaling
circular business models. In particular, shared cross-sector frameworks for metrics,
standardized information models based for example on the Asset Administration
Shell, and the integration of circular metrics into existing systems and processes
are essential. The work presented therefore marks an important step toward a data-driven
and economically viable Circular Economy."

text: 'Scalable plasmonic technologies face a critical trade‐off: few‐body architectures
offer high enhancement but are sensitive to fabrication flaws, while scalable
methods like solid‐state dewetting yield large, low‐enhancement gaps. We introduce
a paradigm shift using a many‐body plasmonic architecture inspired by statistical
mechanics. By moving toward the continuum limit, local geometric variations are
statistically averaged out, effectively decoupling optical performance from microscopic
disorder. We implement this concept via a lithography‐ and etching‐free, multi‐step
dewetting strategy, creating wafer‐scale nanoclusters. This process strategically
forms a robust many‐body system by introducing numerous small satellite nanoparticles
between larger particles. Crucially, this design achieves a high collective enhancement
that surpasses even optimized few‐body systems, despite having larger individual
gaps. Under optimized conditions, these substrates exhibit a surface‐enhanced
Raman scattering enhancement factor approaching 4 × 10^8 with unprecedented reproducibility
(RSD of ∼10%). This scalable, low‐cost concept establishes a practical route toward
reproducible wafer‐scale nanophotonic platforms for sensing, spectroscopy, and
quantum technologies.'

text: "Im ComeMINT-Netzwerk wurde für das Fach Physik ein zweiphasiges Fortbildungskonzept
zum Einsatz digitaler Medien im Physikunterricht entwickelt. Die erste Phase besteht
aus einem Online-Selbstlernkurs auf der Plattform iMooX, welcher neben einer Einführung
in das Lernen mit digitalen Medien auch Module zu spezifischen Medien wie z. B.
Erklärvideos, digitale Messwerterfassung, Smartphones im Physikunterricht oder
Mikrocontroller umfasst.\r\nDarauf aufbauend werden vertiefende Präsenzfortbildungen
zu einzelnen Medien an den beteiligten Standorten angeboten, die einen stärkeren
Praxisbezug verfolgen. Der Beitrag stellt neben den Konzepten des Online-Selbstlernkurses
und den Präsenzfortbildungen auch die bisherigen Erfahrungen aus der Implementation
der Fortbildung in die Praxis vor."

abstract:
- lang: eng
text: We introduce a method for determining the sensitivity of any given entangled
two-photon absorption (ETPA) measurement. By modeling all signal and noise contributions
to the measurement, we derive a single numerical value that describes the sensitivity
of the ETPA measurement in Göppert-Mayer units. This allows us to directly compare
vastly different experimental approaches and determine whether ETPA will be detectable
under the given conditions. Therefore we can quantify the effect of any change
to a given experimental apparatus and identify the ideal optimization pathway.

text: "\r\n We develop a framework for identifying nonclassical
speedups in systems with polarization, likewise spin degrees of freedom. By confining
the dynamics to the manifold of angular momentum coherent states, which act as
the classical reference in this case, we compute the speed limit that bounds the
rate of change of the state achievable without generating quantum coherence. A
comparison with the unrestricted quantum speed limit enables the quantitative
identification of speedups arising from polarization nonclassicality. We apply
this framework to the cross-Kerr interaction, demonstrating a persistent speedup
scaling as\r\n \r\n
\ \r\n O\r\n
\ (\r\n \r\n
\ N\r\n \r\n
\ )\r\n \r\n
\ \r\n with the photon number\r\n
\ \r\n
\ N\r\n \r\n ,
with a parity effect in favor of even photon numbers. The results establish polarization
nonclassicality as a genuine dynamical resource, linking quantum coherence to
quantum-enhanced evolution speeds in nonlinear photonic systems.\r\n "

text: "In this work, we build a bridge between the Pólya--Schur program and Voiculescu's
free probability theory. A cornerstone of the former is the Pólya--Benz Theorem,
classifying a central family of real-root preserving operators on the space of
polynomials, as those given by $f(\\partial_z)$ for a Laguerre--Pólya function
$f$ and the derivative operator $\\partial_{z}$. We prove that any free (additive)
infinitely divisible distribution can be attained as the weak limit of root distributions
of Appell polynomials $f_n(\\partial_z)z^n$ as $n\\to\\infty$, for a suitably
chosen sequence $f_n$ of Laguerre--Pólya functions.\r\n Such questions on the
(global) limiting distributions of real rooted polynomials belong to the active
research area of finite free probability. In contrast to its standard tools, our
approach allows for non-compactly supported limiting distributions, (barely) complex
rooted polynomials and even provides the full microscopic description of the roots.
Moreover, we extend our results to differential operators generating free multiplicative
infinitely divisible distributions, to the rectangular free convolution, and to
$f_n(\\partial_z)p_n$ for real rooted polynomials $p_n$, implying a generalization
of the recent connections between the heat flow and free Brownian motion to any
free Lévy process.\r\n As corollaries, we identify free stable distributions
by choosing $f_n$ to be a fixed rescaled Laguerre--Pólya function, and we prove
various convergence results on the zero distributions of Jensen polynomials, e.g.
the limiting root distribution of Jensen polynomial of the Riemann $Ξ$-function
is given by the Cauchy distribution."

text: Efficient detection of near-infrared light at telecommunication wavelengths
remains a central challenge for GaAs-based photonic and optoelectronic devices
due to the absence of linear absorption below the bandgap. Here, we demonstrate
a hybrid nonlinear optoelectronic device that enhances the detection efficiency
of a (001)-oriented GaAs PIN photodiode under telecommunication-wavelength illumination,
where absorption is intrinsically limited to two-photon absorption (2PA). Our
approach relies on the integration of a transferred, nanopatterned 385 nm-thick
(111)-oriented GaAs nanofilm acting as an on-chip nonlinear frequency-conversion
layer. Elliptical GaAs nanoresonators are employed to enhance second-harmonic
generation (SHG) resonantly, converting incident 1550 nm radiation into above-bandgap
photons efficiently absorbed by the underlying diode. Spatially resolved current–voltage
measurements reveal a pronounced enhancement of the detector response in regions
covered by the nanoantennas. The device exhibits a low dark current, while the
metasurface-covered regions show the largest current response under 1560 nm excitation
compared to the bare GaAs(100) diode and the unstructured GaAs(111) film. These
results establish a direct functional link between dielectric metasurface–based
nonlinear frequency conversion and electrical photodetection, providing a viable
route toward integrated sub-bandgap detection schemes.

text: "Abstract\r\n The service
life of fatigue-loaded components that already contain manufacturing‑induced microcracks
is primarily governed by the direction and the rate of fatigue-crack growth. When
multiple loading components (e.g., tension, compression, shear) act simultaneously
but not in temporal synchrony, out‑of‑phase mixed‑mode conditions occur. Such
loadings are typical for automotive chassis parts and mechanically joined sheet‑metal
assemblies. For optimized design of structural components, the crack kinking angle
that occurs under mixed‑mode loading must be predicted as accurately as possible.
At present, however, this is still challenging for out‑of‑phase loading conditions.
To investigate the associated crack kinking behavior, a novel Compact‑Tension‑Shear‑Mini
(CTSM) specimen was developed, enabling controlled generation of plane out-of-phase
mixed-mode loading states. Experiments were performed under various combinations
of cyclic and static mode I and mode II load components and compared with the
analytical predictions of the Out-of-Phase Mixed-Mode (OMM) concept. The measured
crack kinking angles showed very good agreement with the predicted values, with
mean deviations of only a few degrees, demonstrating the validity and reproducibility
of the approach. These findings confirm the applicability of the OMM concept for
describing fatigue‑crack propagation under non‑proportional mixed‑mode loading
and provide a basis for fatigue‑life assessment of clinched joints and other cyclic
multi-axially loaded components."
