text: "Despite the fundamental role the Quantum Satisfiability (QSAT) problem has\r\nplayed
in quantum complexity theory, a central question remains open: At which\r\nlocal
dimension does the complexity of QSAT transition from \"easy\" to \"hard\"?\r\nHere,
we study QSAT with each constraint acting on a $k$-dimensional and\r\n$l$-dimensional
qudit pair, denoted $(k,l)$-QSAT. Our first main result shows\r\nthat, surprisingly,
QSAT on qubits can remain $\\mathsf{QMA}_1$-hard, in that\r\n$(2,5)$-QSAT is $\\mathsf{QMA}_1$-complete.
In contrast, $2$-SAT on qubits is\r\nwell-known to be poly-time solvable [Bravyi,
2006]. Our second main result\r\nproves that $(3,d)$-QSAT on the 1D line with
$d\\in O(1)$ is also\r\n$\\mathsf{QMA}_1$-hard. Finally, we initiate the study
of 1D $(2,d)$-QSAT by\r\ngiving a frustration-free 1D Hamiltonian with a unique,
entangled ground state.\r\n Our first result uses a direct embedding, combining
a novel clock\r\nconstruction with the 2D circuit-to-Hamiltonian construction
of [Gosset, Nagaj,\r\n2013]. Of note is a new simplified and analytic proof for
the latter (as\r\nopposed to a partially numeric proof in [GN13]). This exploits
Unitary Labelled\r\nGraphs [Bausch, Cubitt, Ozols, 2017] together with a new \"Nullspace
Connection\r\nLemma\", allowing us to break low energy analyses into small patches
of\r\nprojectors, and to improve the soundness analysis of [GN13] from\r\n$\\Omega(1/T^6)$
to $\\Omega(1/T^2)$, for $T$ the number of gates. Our second\r\nresult goes via
black-box reduction: Given an arbitrary 1D Hamiltonian $H$ on\r\n$d'$-dimensional
qudits, we show how to embed it into an effective null-space\r\nof a 1D $(3,d)$-QSAT
instance, for $d\\in O(1)$. Our approach may be viewed as a\r\nweaker notion of
\"simulation\" (\\`a la [Bravyi, Hastings 2017], [Cubitt,\r\nMontanaro, Piddock
2018]). As far as we are aware, this gives the first\r\n\"black-box simulation\"-based
$\\mathsf{QMA}_1$-hardness result, i.e. for\r\nfrustration-free Hamiltonians."

text: "Estimating ground state energies of many-body Hamiltonians is a central task\r\nin
many areas of quantum physics. In this work, we give quantum algorithms\r\nwhich,
given any $k$-body Hamiltonian $H$, compute an estimate for the ground\r\nstate
energy and prepare a quantum state achieving said energy, respectively.\r\nSpecifically,
for any $\\varepsilon>0$, our algorithms return, with high\r\nprobability, an
estimate of the ground state energy of $H$ within additive\r\nerror $\\varepsilon
M$, or a quantum state with the corresponding energy. Here,\r\n$M$ is the total
strength of all interaction terms, which in general is\r\nextensive in the system
size. Our approach makes no assumptions about the\r\ngeometry or spatial locality
of interaction terms of the input Hamiltonian and\r\nthus handles even long-range
or all-to-all interactions, such as in quantum\r\nchemistry, where lattice-based
techniques break down. In this fully general\r\nsetting, the runtime of our algorithms
scales as $2^{cn/2}$ for $c<1$, yielding\r\nthe first quantum algorithms for low-energy
estimation breaking the natural\r\nbound based on Grover search. The core of our
approach is remarkably simple,\r\nand relies on showing that any $k$-body Hamiltonian
has a low-energy subspace\r\nof exponential dimension."

text: "We investigate the role of energy, i.e. average photon number, as a resource\r\nin
the computational complexity of bosonic systems. We show three sets of\r\nresults:
(1. Energy growth rates) There exist bosonic gate sets which increase\r\nenergy
incredibly rapidly, obtaining e.g. infinite energy in finite/constant\r\ntime.
We prove these high energies can make computing properties of bosonic\r\ncomputations,
such as deciding whether a given computation will attain infinite\r\nenergy, extremely
difficult, formally undecidable. (2. Lower bounds on\r\ncomputational power) More
energy ``='' more computational power. For example,\r\ncertain gate sets allow
poly-time bosonic computations to simulate PTOWER, the\r\nset of deterministic
computations whose runtime scales as a tower of\r\nexponentials with polynomial
height. Even just exponential energy and $O(1)$\r\nmodes suffice to simulate NP,
which, importantly, is a setup similar to that of\r\nthe recent bosonic factoring
algorithm of [Brenner, Caha, Coiteux-Roy and\r\nKoenig (2024)]. For simpler gate
sets, we show an energy hierarchy theorem. (3.\r\nUpper bounds on computational
power) Bosonic computations with polynomial\r\nenergy can be simulated in BQP,
``physical'' bosonic computations with\r\narbitrary finite energy are decidable,
and the gate set consisting of Gaussian\r\ngates and the cubic phase gate can
be simulated in PP, with exponential bound\r\non energy, improving upon the previous
PSPACE upper bound. Finally, combining\r\nupper and lower bounds yields no-go
theorems for a continuous-variable\r\nSolovay--Kitaev theorem for gate sets such
as the Gaussian and cubic phase\r\ngates."

text: "The Quantum k-SAT problem is the quantum generalization of the k-SAT problem.\r\nIt
is the problem whether a given local Hamiltonian is frustration-free.\r\nFrustration-free
means that the ground state of the k-local Hamiltonian\r\nminimizes the energy
of every local interaction term simultaneously. This is a\r\ncentral question
in quantum physics and a canonical QMA_1-complete problem. The\r\nQuantum k-SAT
problem is not as well studied as the classical k-SAT problem in\r\nterms of special
tractable cases, approximation algorithms and parameterized\r\ncomplexity. In
this paper, we will give a graph-theoretic study of the Quantum\r\nk-SAT problem
with the structures core and radius. These hypergraph structures\r\nare important
to solve the Quantum k-SAT problem. We can solve a Quantum k-SAT\r\ninstance in
polynomial time if the derived hypergraph has a core of size n-m+a,\r\nwhere a
is a constant, and the radius is at most logarithmic. If it exists, we\r\ncan
find a core of size n-m+a with the best possible radius in polynomial time,\r\nwhereas
finding a general minimum core with minimal radius is NP-hard."

text: Local droplet etching and subsequent refilling enables the fabrication
of highly symmetric quantum dots with low fine structure splitting, suitable for
generating polarization entangled photons. While well established in GaAs/AlxGa1−xAs,
this approach does not yield emission in the telecom bands required for low loss
fiber-based quantum communication. To achieve emission at 1.55 μm, local droplet
etching must be adapted to alternative material platforms such as InP. Here, we
systematically investigate how the etching material deposition rate and etching
time influence nanohole morphology in In0.52Al0.48As layers lattice-matched to
InP. In the first experiment, InAl was deposited at fluxes of 0.2–4.0 Å s−1 at
Tetch = 350 °C and 460 °C. Lower fluxes produced nanoholes with lower density
and larger ring diameters, indicating fewer and larger initial droplets, consistent
with scaling theory. The average nanohole diameter decreased monotonically with
increasing flux, whereas the average depth showed no clear dependence on flux.
In the second experiment, etching times of 30–600 s were tested for InAl, In,
and Al droplets. Average nanohole diameters remained constant for Al across all
etching times, but decreased for In and InAl with increasing etching time, suggesting
sidewall redeposition during etching. For all droplet types, depths peaked at
intermediate times and decreased for prolonged etching, consistent with material
diffusion into the nanohole after droplet consumption.

text: Abstract. Saving emissions and a circular economy are key aspects
of sustainable production and compliance global climate change targets. Friction-induced
solid-state recycling of aluminum scrap to production endless semi-finished products.
Scrap is fed into a continuously rotating wheel. This requires less energy compared
to heat-based recycling processes. Different sizes, shapes and surfaces of chips
can be used as starting material in the process. The influence of this has been
shown in past publications. A native oxide layer is a fixed component of aluminum
surface. This layer is broken up during the forming process, allowing the aluminum
to bond. In addition to the geometry, the surface finishes and the thickness of
the oxide layer are therefore also important input variables in friction-induced
solid-state recycling. The oxide layers on the chips were determined for the investigation.
In addition, different layer thicknesses were produced to survey their influence.
The resulting semi-finished products were evaluated on the basis of their tensile
strength and microstructure. The main result of the investigations is the fact
that semi-finished products made from chips with thicker oxide layers tend to
be more brittle. In addition, thick oxide layers cause microstructural and surface
defects.

text: "Die Extrusion stellt das mengenmäßig dominante Verarbeitungsverfahren für
thermoplastische Kunststoffe dar. Daher gibt es starke Bestrebungen in diesem
Bereich hin zu einer höheren Wirtschaftlichkeit, welche beispielsweise durch höheren
Massedurchsatz bei gleichbleibender Maschinengröße erreicht werden kann, oder
aber auch im Hinblick auf eine Kreislaufwirtschaft die Bestrebung hin zu einer
materialschonenden Verarbeitung. Beide Bestrebungen erfordern spezielle Schneckenkonzepte.
Hierunter fallenWave- Schnecken, welche in beiden Bereichen ein vorteilhaftes
Prozessverhalten aufzeigen sollen. Die Auslegung von Wave-Schnecken erfordert
jedoch ein stärkeres Verständnis über das geometrieabhängige Prozessverhalten
in der Extrusion. \r\nIm Rahmen der Dissertation werden zwei Themengebiete angegangen.
Das erste Thema ist die Herleitung einer Methode zur Charakterisierung des Abbauverhaltens
von Thermoplasten sowie die Nutzung der Charakterisierung als Vorhersagemodell.
Das zweite Thema behandelt die Auslegung von Wave-Schnecken basierend auf numerischen
Simulationen samt Validierung anhand von sieben Energy-Transfer-Schnecken im Vergleich
zu drei konventionellen Schnecken. Hierbei werden unter anderem der Materialabbau,
die thermische und die stoffliche Homogenität betrachtet, um ein umfassendes Bild
über das Prozessverhalten der Schnecken zu schaffen. Die vorgestellten Untersuchungen
dienen schlussendlich zu einer Bestätigung des vorteilhaften Prozessverhaltens
von Wave-Schnecken."

text: "The extrusion process is the dominant processing method for thermoplastics
in terms of quantity. For this reason, there are strong efforts in this area towards
greater economic efficiency, which can be achieved, for example, through higher
mass throughput with the same machine size, or, with regard to a circular economy,
towards material-preserving processing. Both endeavours require special screw
concepts. These include wave screws, which should demonstrate advantageous process
behaviour in both areas. However, the design of wave screws requires a better
understanding of the geometry-dependent process behaviour in extrusion. \r\nTwo
topics are addressed in the dissertation. The first topic is the derivation of
a method to characterise the degradation behaviour of thermoplastics and the use
of the characterisation as a predictive model. The second topic deals with the
design of wave screws based on numerical simulations including validation using
seven energy transfer screws in comparison to three conventional screws. Among
other things, the material degradation, the thermal and the material homogeneity
are considered in order to create a comprehensive picture of the process behaviour
of the screws. The presented investigations ultimately serve to confirm the advantageous
process behaviour of wave screws."

text: 'Ferroelectric domain wall (DW) conductivity (DWC) can be attributed to two
separate mechanisms: (a) the injection/ejection of charge carriers across the
Schottky barrier formed at the (metal-)electrode-DW junction and (b) the transport
of those charge carriers along the DW. Current-voltage (I-U) characteristics,
recorded at variable temperatures from LiNbO3 (LNO) DWs, are clearly able to differentiate
between these two contributions. Practically, they allow us to directly quantify
the physical parameters relevant to the two mechanisms (a) and (b) mentioned above.
These are, for example, the resistance of the DW, the saturation current, the
ideality factor, and the Schottky barrier height of the electrode-DW junction.
Furthermore, the activation energies needed to initiate the thermally activated
electronic transport along the DWs can be extracted. In addition, we show that
electronic transport along LNO DWs can be elegantly viewed and interpreted in
an adapted semiconductor picture based on a double-diode, double-resistor equivalent-circuit
model, the R2D2 model. Finally, our R2D2 model was checked for its universality
by successfully fitting the I-U curves of not only z-cut LNO bulk DWs, but equally
of z-cut thin-film LNO DWs, and of x-cut thin-film DWs as reported in literature.'

text: AbstractPolycarbonate (PC) is an amorphous
polymer that is an extremely robust material with a high tenacity, and thus suitable
for a lightweight construction with glass‐like transparency. Due to these advantageous
properties, PC is often used in industry for example in medical devices, automotive
headlamps, sporting equipment, electronics, and a variety of other products. PC
is often subjected to uniaxial and biaxial loading conditions. Therefore, reliable
material models have to take into account the various resulting experimental effects.
For those reasons, we investigate PC specimens under uniaxial and biaxial loading
by using different stretch rates and loading scenarios. In addition to that, we
propose methods for optical measurement of local stretches to obtain the approximated
local true stress. In future work, the displacement fields and the resulting reaction
forces will be used for parameter identification of constitutive equations.
