text: Lithium niobate (LiNbO3), a material frequently used in optical applications,
hosts different kinds of polarons that significantly affect many of its physical
properties. In this study, a variety of electron polarons, namely free, bound,
and bipolarons, are analyzed using first-principles calculations. We perform a
full structural optimization based on density-functional theory for selected intrinsic
defects with special attention to the role of symmetry-breaking distortions that
lower the total energy. The cations hosting the various polarons relax to a different
degree, with a larger relaxation corresponding to a larger gap between the defect
level and the conduction-band edge. The projected density of states reveals that
the polaron states are formerly empty Nb 4d states lowered into the band gap.
Optical absorption spectra are derived within the independent-particle approximation,
corrected by the GW approximation that yields a wider band gap and by including
excitonic effects within the Bethe-Salpeter equation. Comparing the calculated
spectra with the density of states, we find that the defect peak observed in the
optical absorption stems from transitions between the defect level and a continuum
of empty Nb 4d states. Signatures of polarons are further analyzed in the reflectivity
and other experimentally measurable optical coefficients.

text: Multimode integrated interferometers have great potential for both
spectral engineering and metrological applications. However, the material dispersion
of integrated platforms constitutes an obstacle that limits the performance and
precision of such interferometers. At the same time, two-colour nonlinear interferometers
present an important tool for metrological applications, when measurements in
a certain frequency range are difficult. In this manuscript, we theoretically
developed and investigated an integrated multimode two-colour SU(1,1) interferometer
operating in a supersensitive mode. By ensuring the proper design of the integrated
platform, we suppressed the dispersion, thereby significantly increasing the visibility
of the interference pattern. The use of a continuous wave pump laser provided
the symmetry between the spectral shapes of the signal and idler photons concerning
half the pump frequency, despite different photon colours. We demonstrate that
such an interferometer overcomes the classical phase sensitivity limit for wide
parametric gain ranges, when up to 3×104 photons are generated.

text: Lithium niobate on insulator (LNOI) has a great potential for photonic integrated
circuits, providing substantial versatility in design of various integrated components.
To properly use these components in the implementation of different quantum protocols,
photons with different properties are required. In this paper, we theoretically
demonstrate a flexible source of correlated photons built on the LNOI waveguide
of a special geometry. This source is based on the parametric down-conversion
(PDC) process, in which the signal and idler photons are generated at the telecom
wavelength and have different spatial profiles and polarizations, but the same
group velocities. Distinguishability in polarizations and spatial profiles facilitates
the routing and manipulating individual photons, while the equality of their group
velocities leads to the absence of temporal walk-off between photons. We show
how the spectral properties of the generated photons and the number of their frequency
modes can be controlled depending on the pump characteristics and the waveguide
length. Finally, we discuss special regimes, in which narrowband light with strong
frequency correlations and polarization-entangled Bell states are generated at
the telecom wavelength.

text: Quantum walks function as essential means to implement quantum simulators,
allowing one to study complex and often directly inaccessible quantum processes
in controllable systems. In this contribution, the notion of a driven Gaussian
quantum walk is introduced. In contrast to typically considered quantum walks
in optical settings, we describe the operation of the walk in terms of a nonlinear
map rather than a unitary operation, e.g., by replacing a beam-splitter-type coin
with a two-mode squeezer, being a process that is controlled and driven by a pump
field. This opens previously unattainable possibilities for quantum walks that
include nonlinear elements as core components of their operation, vastly extending
their range of applications. A full framework for driven Gaussian quantum walks
is developed, including methods to dynamically characterize nonlinear, quantum,
and quantum-nonlinear effects. Moreover, driven Gaussian quantum walks are compared
with their classically interfering and linear counterparts, which are based on
classical coherence of light rather than quantum superpositions. In particular,
the generation and boost of highly multimode entanglement, squeezing, and other
quantum effects are studied over the duration of the nonlinear walk. Importantly,
we prove the quantumness of the evolution itself, regardless of the input state.
A scheme for an experimental realization is proposed. Furthermore, nonlinear properties
of driven Gaussian quantum walks are explored, such as amplification that leads
to an ever increasing number of correlated quantum particles, constituting a source
of new walkers during the walk. Therefore, a concept for quantum walks is proposed
that leads to—and even produces—directly accessible quantum phenomena, and that
renders the quantum simulation of nonlinear processes possible.

text: "Anwendungen von Laser-Sinter Bauteilen als Sichtteile sind aufgrund der vergleichsweise
schlechten Oberflächenqualität sehr begrenzt. In dieser Arbeit werden dreidimensionale
Kennwerte benutzt, um die Oberflächenqualität von Laser-Sinter Bauteiloberflächen
und die Einflüsse aus unterschiedlichen Bereichen der gesamten Prozesskette zu
evaluieren. Beispielsweise wurden objektive Kennwerte, mit deren Hilfe Orangenhaut
zu identifizieren ist, und Prozessparameter, die diese deutlich vermindern, gefunden.
Mittels Durchführung von haptischen Versuchen wurde das subjektive Empfinden ermittelt
und konnten zu objektiven Kennwerten korreliert werden. Eine mikroskopische Betrachtung
des flachen Oberflächenwinkels mit verschieden farbigen Pulvern zeigt neue Erkenntnisse
zum Anschmelzvorgang von Partikeln an die Schmelze. Zur nachträglichen Glättung
von Oberflächen wurden mechanische, chemische und optische Nachbehandlungsmethoden
verwendet und deren Potential aufgezeigt. Eine abschließende neuartige Simulation
der dreidimensionalen Topografie bildet die Grundlage für ein Programm zur automatischen
und funktionsgerechten Orientierung von Bauteilen, welche am Beispiel eines realen
Bauteils erfolgreich validiert wurde. Zusammengenommen zeigen die Ergebnisse,
dass die richtige Wahl von Bauorientierung und Prozessparametern entscheidend
für die Bauteilqualität ist und selbst eine aufwendige Nachbearbeitung eine ungeschickte
Wahl derer nur schwerlich ausgleichen kann.\r\n"

text: "Das Fused Deposition Modeling (FDM) ist ein Verfahren zur additiven Fertigung
(AF), welches von der Firma Stratasys Ltd. (früher Stratasys Inc.) kommerzialisiert
wurde. Heute existieren auch FDM Maschinen anderer Hersteller. Im Gegensatz zu
den Maschinen von Stratasys können bei diesen die Prozessparameter frei gewählt
werden. Dadurch ist die Verarbeitung herstellerfremder Materialien möglich. Wie
in allen AF-Verfahren, werden im FDM bestimmte Anforderungen an die zu verarbeitenden
Materialien gestellt. Die Materialien sollten daher speziell für das FDM ausgewählt
bzw. entwickelt werden. Die für eine gute Verarbeitbarkeit notwendigen Materialeigenschaften
sind aktuell jedoch nicht hinreichend bekannt. Vielmehr sind auch keine Vorgehensweisen
bekannt, um die Verarbeitungseignung verschiedener Materialien im FDM zu bewerten.\r\nIm
Rahmen dieser Arbeit werden daher Vorgehensweisen vorgestellt, um die Verarbeitungseignung
thermoplastischer Kunststoffe im FDM anhand bestimmter Merkmale zu bewerten. Die
Schweißnahtqualität, der Bauteilverzug und die Gestaltungsfreiheit werden als
wichtige Merkmale identifiziert. Unter Beachtung relevanter Einflussgrößen werden
je Merkmal Probekörper und Prüfmethoden entwickelt, um merkmalspezifische Kennwerte
zu definieren. Dadurch ist der Vergleich unterschiedlicher Materialien, unabhängig
von der verwendeten Maschine und der Datenaufbereitung, möglich. Letztendlich
werden verschiedene Materialmodifikationen auf Basis von PA 6 erstellt und mit
Hilfe der vorgestellten Vorgehensweisen untersucht und bewertet."

text: The nonlinear process of second harmonic generation (SHG) in monolayer (1L)
transition metal dichalcogenides (TMD), like WS2, strongly depends on the polarization
state of the excitation light. By combination of plasmonic nanostructures with
1L-WS2 by transferring it onto a plasmonic nanoantenna array, a hybrid metasurface
is realized impacting the polarization dependency of its SHG. Here, we investigate
how plasmonic dipole resonances affect the process of SHG in plasmonic–TMD hybrid
metasurfaces by nonlinear spectroscopy. We show that the polarization dependency
is affected by the lattice structure of plasmonic nanoantenna arrays as well as
by the relative orientation between the 1L-WS2 and the individual plasmonic nanoantennas.
In addition, such hybrid metasurfaces show SHG in polarization states, where SHG
is usually forbidden for either 1L-WS2 or plasmonic nanoantennas. By comparing
the SHG in these channels with the SHG generated by the hybrid metasurface components,
we detect an enhancement of the SHG signal by a factor of more than 40. Meanwhile,
an attenuation of the SHG signal in usually allowed polarization states is observed.
Our study provides valuable insight into hybrid systems where symmetries strongly
affect the SHG and enable tailored SHG in 1L-WS2 for future applications.

text: Processing aluminum alloys employing powder bed fusion of metals (PBF-LB/M)
is becoming more attractive for the industry, especially if lightweight applications
are needed. Unfortunately, high-strength aluminum alloys such as AA7075 are prone
to hot cracking during PBF-LB/M, as well as welding. Both a large solidification
range promoted by the alloying elements zinc and copper and a high thermal gradient
accompanied with the manufacturing process conditions lead to or favor hot cracking.
In the present study, a simple method for modifying the powder surface with titanium
carbide nanoparticles (NPs) as a nucleating agent is aimed. The effect on the
microstructure with different amounts of the nucleating agent is shown. For the
aluminum alloy 7075 with 2.5 ma% titanium carbide nanoparticles, manufactured
via PBF-LB/M, crack-free samples with a refined microstructure having no discernible
melt pool boundaries and columnar grains are observed. After using a two-step
ageing heat treatment, ultimate tensile strengths up to 465 MPa and an 8.9% elongation
at break are achieved. Furthermore, it is demonstrated that not all nanoparticles
used remain in the melt pool during PBF-LB/M.

text: N-body methods are one of the essential algorithmic building blocks of high-performance
and parallel computing. Previous research has shown promising performance for
implementing n-body simulations with pairwise force calculations on FPGAs. However,
to avoid challenges with accumulation and memory access patterns, the presented
designs calculate each pair of forces twice, along with both force sums of the
involved particles. Also, they require large problem instances with hundreds of
thousands of particles to reach their respective peak performance, limiting the
applicability for strong scaling scenarios. This work addresses both issues by
presenting a novel FPGA design that uses each calculated force twice and overlaps
data transfers and computations in a way that allows to reach peak performance
even for small problem instances, outperforming previous single precision results
even in double precision, and scaling linearly over multiple interconnected FPGAs.
For a comparison across architectures, we provide an equally optimized CPU reference,
which for large problems actually achieves higher peak performance per device,
however, given the strong scaling advantages of the FPGA design, in parallel setups
with few thousand particles per device, the FPGA platform achieves highest performance
and power efficiency.
