text: While plasmonic particles can provide optical resonances in a wide spectral
range from the lower visible up to the near-infrared, often, symmetry effects
are utilized to obtain particular optical responses. By breaking certain spatial
symmetries, chiral structures arise and provide robust chiroptical responses to
these plasmonic resonances. Here, we observe strong chiroptical responses in the
linear and nonlinear optical regime for chiral L-handed helicoid-III nanoparticles
and quantify them by means of an asymmetric factor, the so-called g-factor. We
calculate the linear optical g-factors for two distinct chiroptical resonances
to −0.12 and –0.43 and the nonlinear optical g-factors to −1.45 and −1.63. The
results demonstrate that the chirality of the helicoid-III nanoparticles is strongly
enhanced in the nonlinear regime.

text: AbstractTailored nanoscale quantum light
sources, matching the specific needs of use cases, are crucial building blocks
for photonic quantum technologies. Several different approaches to realize solid-state
quantum emitters with high performance have been pursued and different concepts
for energy tuning have been established. However, the properties of the emitted
photons are always defined by the individual quantum emitter and can therefore
not be controlled with full flexibility. Here we introduce an all-optical nonlinear
method to tailor and control the single photon emission. We demonstrate a laser-controlled
down-conversion process from an excited state of a semiconductor quantum three-level
system. Based on this concept, we realize energy tuning and polarization control
of the single photon emission with a control-laser field. Our results mark an
important step towards tailored single photon emission from a photonic quantum
system based on quantum optical principles.

text: Resonant evanescent coupling can be utilized to selectively excite orbital
angular momentum (OAM) modes of high angular order supported by a thin circular
dielectric rod. Our 2.5-D hybrid-analytical coupled mode model combines the vectorial
fields associated with the fundamental TE- and TM-modes of a standard silicon
photonics slab waveguide, propagating at oblique angles with respect to the rod
axis, and the hybrid modes supported by the rod. One observes an efficient resonant
interaction in cases where the common axial wavenumber of the waves in the slab
matches the propagation constant of one or more modes of the rod. For certain
modes of high angular order, the incident wave is able to transfer its directionality
to the field in the fiber, exciting effectively only one of a pair of degenerate
OAM modes

text: In dieser Arbeit wird die elektromagnetische Wellenausbreitung in integrierten
optischen Wellenleitern mit Hilfe von halb analytischen und numerischen Simulationsmethoden
untersucht. Im ersten Teil werden 2-D Si/SiO2-Wellenleiterkonfigurationen mit
hohem Brechungsindexkontrast betrachtet. Die Strukturen werden mit halb geführten
Wellen unter schrägen Ausbreitungswinkeln angeregt. Dadurch kann die Leistungsübertragung
zu bestimmten ausgehenden Moden unterdrückt werden, wodurch vollständig verlustfreie
Systeme entstehen. Zusätzlich dient die Anregung mit einem seitlich begrenzten,
einfallenden Wellenbündel aus halb geführten Wellen dazu, praktisch relevantere
3-D Konfigurationen zu realisieren. Darüber hinaus wird eine schrittweise Winkelspektrum-Methode
vorgestellt, die es ermöglicht, in Kombination mit voll vektoriellen 2-D Finite-Elemente-Lösungen
für Teilprobleme mit geringerer Komplexität, die Wellenausbreitung in planaren,
linsenförmigen Wellenleitern numerisch in drei Raumrichtungen zu berechnen. Im
zweiten Teil dieser Arbeit wird die Ausbreitung in Wellenleiterstrukturen aus
Lithiumniobat untersucht, welche für quantenoptische Effekte genutzt werden. Zur
Detektion einzelner Photonen werden supraleitende Nanodrähte auf eindiffundierten
Lithiumniobat Wellenleitern mit zusätzlicher Taperschicht aus Silizium betrachtet.
Um die Wellenausbreitung in diesen 3-D Wellenleitern zu beschreiben, wird eine
einseitig gerichtete Finite-Elemente „Modal Matching“ Methode eingeführt. Abschließend
werden Rippenwellenleiter aus Lithiumniobat analysiert, die auf Siliziumdioxid
Plattformen aufgebracht sind. Der Schwerpunkt liegt hier auf dem nichtlinearen
„Parametric Down-Conversion“ Prozess, der für die Erzeugung verschränkter Photonen
verwendet wird.

text: In this work, the electromagnetic wave propagation in integrated optical waveguides
is studied by using semi-analytical and numerical simulation methods. In the first
part, 2-D high-index contrast Si/SiO2 dielectric slab waveguide configurations
are investigated. The structures are excited with semi-guided waves at oblique
angles of propagation. Due to this, power transfer to specific outgoing modes
can be suppressed, resulting in completely lossless configurations. The excitation
is further examined for incoming, laterally confined wave bundles of semi-guided
waves to realize practically more relevant 3-D configurations. Additionally, a
stepwise angular spectrum method in combination with full vectorial 2-D finite
element solutions for subproblems of lower complexity to numerically simulate
the wave propagation in full 3-D planar lens-like waveguides is presented. In
the second part, the wave propagation in lithium niobate waveguide structures
is examined, which are used for quantum optical effects. On the one hand, superconducting
nanowires on titanium in-diffused lithium niobate waveguides with an additional
tapered silicon layer are used for single photon detection. The wave propagation
in these 3-D multiscale tapers is studied by introducing a unidirectional finite
element modal matching method. On the other hand, lithium niobate rib waveguides
on silicon dioxide platforms are analyzed, focusing on the nonlinear parametric
down-conversion process used for the generation of entangled photons.

text: "We consider the combinatorial bandits problem with semi-bandit feedback under\r\nfinite
sampling budget constraints, in which the learner can carry out its\r\naction
only for a limited number of times specified by an overall budget. The\r\naction
is to choose a set of arms, whereupon feedback for each arm in the\r\nchosen set
is received. Unlike existing works, we study this problem in a\r\nnon-stochastic
setting with subset-dependent feedback, i.e., the semi-bandit\r\nfeedback received
could be generated by an oblivious adversary and also might\r\ndepend on the chosen
set of arms. In addition, we consider a general feedback\r\nscenario covering
both the numerical-based as well as preference-based case and\r\nintroduce a sound
theoretical framework for this setting guaranteeing sensible\r\nnotions of optimal
arms, which a learner seeks to find. We suggest a generic\r\nalgorithm suitable
to cover the full spectrum of conceivable arm elimination\r\nstrategies from aggressive
to conservative. Theoretical questions about the\r\nsufficient and necessary budget
of the algorithm to find the best arm are\r\nanswered and complemented by deriving
lower bounds for any learning algorithm\r\nfor this problem scenario."

text: AbstractWe consider the problem of maximization
of metabolite production in bacterial cells formulated as a dynamical optimal
control problem (DOCP). According to Pontryagin’s maximum principle, optimal solutions
are concatenations of singular and bang arcs and exhibit the chattering or Fuller
phenomenon, which is problematic for applications. To avoid chattering, we introduce
a reduced model which is still biologically relevant and retains the important
structural features of the original problem. Using a combination of analytical
and numerical methods, we show that the singular arc is dominant in the studied
DOCPs and exhibits the turnpike property. This property
is further used in order to design simple and realistic suboptimal control strategies.

text: "Algorithm configuration (AC) is concerned with the automated search of the\r\nmost
suitable parameter configuration of a parametrized algorithm. There is\r\ncurrently
a wide variety of AC problem variants and methods proposed in the\r\nliterature.
Existing reviews do not take into account all derivatives of the AC\r\nproblem,
nor do they offer a complete classification scheme. To this end, we\r\nintroduce
taxonomies to describe the AC problem and features of configuration\r\nmethods,
respectively. We review existing AC literature within the lens of our\r\ntaxonomies,
outline relevant design choices of configuration approaches,\r\ncontrast methods
and problem variants against each other, and describe the\r\nstate of AC in industry.
Finally, our review provides researchers and\r\npractitioners with a look at future
research directions in the field of AC."

text: Federkraftbremsen sind weit verbreitete Komponenten der Antriebstechnik, ansteigend
mit abnehmender Größe erreichen sie aktuell Drehzahlen von bis zu 5 000 min−1.
Es besteht ein Trend zu schnell laufenden Antrieben, mit Drehzahlen von 10 000
min−1 und darüber. Bisher sind wenig Kenntnisse über das Verhalten des Reibwerts
und -moments herkömmlicher Federkraftbremsen mit kostengünstigen organischen Reibbelägen
bei diesen Einsatzbedingungen bekannt. Daher wurde ein Prüfstand entwickelt, der
die Untersuchung bei Gleitgeschwindigkeiten von bis zu 50 m/s bei verschiedenen
Lastträgheiten ermöglicht. Die Versuche zeigten, dass bei begrenzten Reibarbeiten
die herkömmliche Federkraftbremse durchaus das Nennbremsmoment bei höheren Gleitgeschwindigkeiten
erreicht.

text: "Context: The implementation of successful measures to support immigrants'
integration in cultural, social, and economic life can be considered as one of
today's greatest challenges for many societies. This is especially true for adolescent
immigrants who have not yet been able to finish education or gain qualifications
relevant to joining the labour market. That is why many receiving countries have
developed and implemented special programmes that aim at supporting immigrants'
integration by facilitating their employability. Unfortunately, not much is known
about the process of implementing these programmes or about how education systems,
schools, and teachers are dealing with the new situation and target group. In
this contribution, the implementation, development, and challenges of German Vocational
Integration Classes (VIC), as an example of comparable programmes in the EU, are
investigated to address this research gap. The paper considers the following exploratory
research questions: (a) What challenges have been experienced by teachers and
social workers in the implementation of VIC as well as in the integration of immigrants
into the labour market in recent years? (b) How can these challenges be met in
the long run and how should VIC be developed to better achieve its aims? \r\n\r\nMethods:
To answer these questions, a sequential qualitative study containing questionnaire
and interview elements was conducted. First, teachers and social workers involved
in VIC filled in a questionnaire about their experiences and experienced challenges
in implementing VIC (N = 46). Then, supplementing interviews were conducted with
participants from the first sample in order to generate further insights and to
contextualise the findings from the first study part (N = 14). \r\n\r\nFindings:
From the respondents' answers, it appears that the VIC programme is well implemented.
The results show, however, that central challenges continue to exist. This concerns,
for example, legal regulations or the development of adequate curricula, but also
the scope and quality of language education. In addition, problems have also been
identified with regard to students' culture-specific education and their individual
attitudes. These prevailing problems seem to affect schooling and educational
processes. In addition, respondents report feeling left alone to deal with problems
and that their experiences from their daily work in VIC and with immigrants are
not sufficiently taken into account in policy and school-related decisions. \r\n\r\nConclusions:
Although VIC seems well implemented, key challenges remain in the view of the
participants. It was found that teachers cannot solve many of the identified problems
themselves, as they require action at the level of policy or school organisation.
For staff, this can be accompanied by increased stress and demotivation. For the
young immigrants, the existing challenges can have a long-term impact on school
success and transition to vocational education and training. The study thus highlights
the importance of targeted and holistic strategies to support immigrant integration
through education. "
