Optically induced spin-dependent diffusive transport in the presence of spin-orbit interaction for all-optical magnetization reversal

description: We have considered the effect of different spin-orbit interaction mechanisms on the process of demagnetization under the influence of short-pulse lasers. All-optical magnetization reversal of perpendicularly magnetized thin films can occur if there are sufficient strong spin-Hall, skew scattering, and Rashba interactions. In the presence of spin-orbit interactions, the transient charge currents provide the generation of transverse-spin currents and accumulations, which eventually exert spin-transfer torque on the magnetization. By combining the optically excited spin-dependent diffusive transport with the spin and charge currents due to skew scattering, spin-Hall, inverse spin-Hall and Rashba interactions, into a numerical model, we demonstrate a possibility of ultra-fast all-optical magnetization reversal. This understanding provokes intriguing, more in-depth experimental studies on the role of spin-orbit interaction mechanisms in optimizing structures for all-optical magnetization reversal.

Mathematical Research Data Initiative
Interdisciplinary Workflows

description: The Mathematical Research Data Initiative (MaRDI) has set itself the goal of making information about mathematical objects, e.g. algorithms or models, available in a structured and easy-to-find manner in the form of a knowledge graph. The linking of all these objects with concrete questions, input and output data, software and hardware is done in specific workflows. To achieve reproducibility of these often interdisciplinary workflows, detailed documentation is required. For this purpose, a standardized template for workflow documentation was developed in the MaRDI project, which can be completed by answering a simple questionnaire in RDMO. Workflows recorded in this way can be stored locally or published directly on the MaRDI portal. In addition, central information of the documentations is integrated into the MaRDI Knowledge Graph. Next to the pure documentation of workflows, MaRDMO offers the possibility to retrieve existing workflows from the MaRDI Knowledge Graph in order to provide researchers with suggestions for future projects and to document workflows based on these suggestions. Thus, MaRDMO creates a community-driven knowledge loop that could help to overcome the replication crisis.
Kepler-108: A Mutually Inclined Giant Planet System

description: The vast majority of well studied giant-planet systems, including the Solar System, are nearly coplanar which implies dissipation within a primordial gas disk. however, intrinsic instability may lead to planet-planet scattering, which often produces non-coplanar, eccentric orbits. Planet scattering theories have been developed to explain observed high eccentricity systems and also hot Jupiters; thus far their predictions for mutual inclination (I) have barely been tested. Here we characterize a highly mutually-inclined (I ~ 15-60 degrees), moderately eccentric (e >~ 0.1) giant planet system: Kepler-108. This system consists of two approximately Saturn-mass planets with periods of ~49 and ~190 days around a star with a wide (~300AU) binary companion in an orbital configuration inconsistent with a purely disk migration origin.

description: We describe a new technique to obtain representations of the braid group B_n from the R-matrix of a quantum deformed algebra of the one dimensional harmonic oscillator. We consider the action of the R-matrix not on the tensor product of representations of the algebra, that in the harmonic oscillator case are infinite dimensional, but on the subspace of the tensor product corresponding to the lowest weight vectors.
The cross-over from tunnelling to multiphoton ionization of atoms

subject: FOS: Physical sciences

description: We present a theory illuminating the cross-over from strong-field tunnelling ionization to weak-field multiphoton ionization in the interaction of a classical laser field with a hydrogen atom. A simple formula is derived in which the ionization amplitude appears as a product of two separate amplitudes. The first describes the initial polarization of the atom by virtual multiphoton absorption and the second the subsequent tunnelling out of the polarized atom. Tunnelling directly from the ground state and multiphoton absorption without tunnelling appear naturally as the limits of the theory.

title: Evaluation and Optimisation of the Small Ring Test and its Amalgamation with the Small Punch Test
Creators: name: Joshi, Aniket
Publisher: name: The Open University
Year: 2023

description: This thesis explores the limitations of conventional mechanical testing methods and assesses two miniaturised specimen testing techniques: the small ring test (SRT) and the small punch test (SPT). Given the nascency of the SRT, especially as a tensile test, this thesis rigorously assesses the SRT for 48 pin displacement rates on Stainless Steel (Grade 316L), employing machine learning and inter-test comparison to evaluate rate dependency. The gathered data facilitates new conversion relationships for translating SRT data to equivalent stress-strain data. Material properties are obtained through inverse finite element analysis and optimisation routines, with test standardisation recommendations also proposed. Next, Digital image correlation (DIC) is applied to various SRT ring specimen locations, suggesting the design of an extensometer for the SRT. A 30° claw-like extensometer, gripping the ring at 30° points on either side of the horizontal axis, is found to be optimal. This thesis also studies the concurrent use of SRT and SPT, where SPT specimens are machined from the SRT’s blank space. Consequently, two discs are extracted from each SRT ring’s blank space and their results are compared with those from discs extracted normally. This combined testing method is applied to SS-316L, Nimonic-75 creep tests, and a plate with weld deposits. The SRT reveals encouraging results, showing a good match between the rings extracted normally and those with discs taken from their blank space. Despite rig compliance issues inhibiting proper result conversion for the SPT, the approach exhibits potential, as the results for discs from the ring’s blank space align well with normally extracted discs. The combination shows encouraging results, suggesting future research on different materials. It offers substantial material savings by theoretically reducing the volumetric material required by 97.89% compared to conventional uniaxial testing.

description: Cross-correlations between biased tracers and the dark matter field encode information about the physical variables which characterize these tracers. However, if the physical variables of interest are correlated with one another, then extracting this information is not as straightforward as one might naively have thought. We show how to exploit these correlations so as to estimate scale-independent bias factors of all orders in a model-independent way. We also show that failure to account for this will lead to incorrect conclusions about which variables matter and which do not. Morever, accounting for this allows one to use the scale dependence of bias to constrain the physics of halo formation; to date the argument has been phrased the other way around. We illustrate by showing that the scale dependence of linear and nonlinear bias, measured on nonlinear scales, can be used to provide consistent estimates of how the critical density for halo formation depends on halo mass. Our methods work even when the bias is nonlocal and stochastic, such as when, in addition to the spherically averaged density field and its derivatives, the quadrupolar shear field also matters for halo formation. In such models, the nonlocal bias factors are closely related to the more familiar local nonlinear bias factors, which are much easier to measure. Our analysis emphasizes the fact that biased tracers are biased because they do not sample fields (density, velocity, shear, etc.) at all positions in space in the same way that the dark matter does.

description: In diesem Jahr lässt sich für den deutschen Schiffbau, welcher fortführend einen strukturellen Wandel durchläuft, konstatieren, dass sich neben den verschiedenen Unternehmensverkäufen und Übernahmen ebenfalls Möglichkeiten abzeichnen, mit koordiniertem Strukturen und Entscheidungen die Situationen der maritimen Wirtschaft zu kräftigen. Im dritten Jahr in Folge muss der deutsche Schiffbau einen erneuten Beschäftigungsrückgang verkraften. Im September 2011 sind mit 16.351 direkt Beschäftigten auf allen deutschen Werften 3,9 Prozent, d.h. 409 Personen weniger beschäftigt als noch ein Jahr zuvor. Verglichen mit dem Jahr 2008 fällt die Bilanz noch negativer aus: seit dem September 2008 haben rund 4.179 Arbeitnehmer/innen ihren Job auf der Werft verloren – ein Rückgang um 20,4 Prozent. In Anlehnung an die Ergebnisse des Vorjahres, welche bestätigten, dass ein Ende des Containerschiffbaus hin zu einer Konzentration auf die Fertigung von Spezialschiffen erfolgt, lässt sich mittlerweile in der aufkommenden Offshore-Windenergie-Branche eine Chance erkennen, dass deutsche Werften Aufträge in diesen Bereichen akquirieren können.

description: This paper investigates how the development of AI-related inventions by Multinational Enterprises (MNEs) affects their technological trajectories and innovative performance. I combine a matched-pair analysis with an extension of the Difference-in-Difference method to analyse these effects over a novel panel dataset of MNEs. This dataset links over 30 thousand MNEs to more than 10 million patents that these companies owned directly or indirectly (i.e., through their subsidiaries) in the period from 2011 to 2019. The results indicate that MNEs introducing AI-related inventions increase the relatedness of subsequent inventions by about 10 per cent compared to a control group. These results are robust when accounting for a self-selection bias. AI is thus being used to reinforce the existing technological trajectories, rather than to disrupt them. The results also suggest that the number of subsequent inventions is about 40 per cent higher for MNEs that introduce AI during the observation period compared to the control group, without significant effects on the intensity of R&D expenditures per invention. It is argued that this increase in innovative performance is linked not only to knowledge dynamics created by learning about AI but also by AI’s technical potential to be used for learning.

Thermal effects of a photon gas with a deformed Heisenberg algebra

description: In this paper we have consider the thermodynamics of a photon gas subject to the presence of a minimal measurable length following from a covariant extension of the original generalized uncertainty principle (GUP). After establishing consistently a generalized dynamics, we define a GUP deformed Maxwell invariant which serves as the basis for our study. In order to highlight the GUP effects we compute the one- and two-loop order contribution to the partition function at the high-temperature limit. Afterwards, by computing the internal energy density we conclude that the additional terms can be seen as corrections $δσ_{\rm{gup}}$ to the Stefan-Boltzmann law due to GUP effects.

description: To understand complex physics of a system with strong electron electron interactions, it is ideal to control and monitor its properties while tuning an external electric field applied to the system. Indeed, complete electric field control of many body states in strongly correlated electron systems is fundamental to the next generation of condensed matter research and devices. However, the material must be thin enough to avoid shielding of the electric field in bulk material. Two-dimensional materials do not experience electrical screening, and their charge carrier density can be controlled by gating. 1T TiSe2 is a prototypical 2D material that shows charge density wave(CDW) and superconductivity in its phase diagram, presenting several similarities with other layered systems such as copper oxides, iron pnictides, crystals of rare-earth and actinide atoms. By studying 1T TiSe2 single crystals with thicknesses of 10 nm or less, encapsulated in 2D layers of hexagonal boron nitride, we achieve unprecedented control over the CDW transition temperature, tuned from 170 K to 40 K, and over the superconductivity transition temperature, tuned from a quantum critical point at 0 K up to 3 K. Electrically driving TiSe2 over different ordered electronic phases allows us to study the details of the phase transitions between many-body states. Observations of periodic oscillations of magnetoresistance induced by the Little Parks effect show that the appearance of superconductivity is directly correlated to the spatial texturing of the amplitude and phase of the superconductivity order parameter, corresponding to a 2D matrix of superconductivity. We infer that this superconductivity matrix is supported by a matrix of incommensurate CDW states embedded in the commensurate CDW states. Our results show that spatially modulated electronic states are fundamental to the appearance of 2D superconductivity.

description: The interaction of cosmic rays with the gas contained in our Galaxy is a guaranteed source of diffuse high energy neutrinos. We provide expectations for this component by considering different assumptions for the cosmic ray distribution in the Galaxy which are intended to cover the large uncertainty in cosmic ray propagation models. We calculate the angular dependence of the diffuse galactic neutrino flux and the corresponding rate of High Energy Starting Events in IceCube by including the effect of detector angular resolution. Moreover we discuss the possibility to discriminate the galactic component from an isotropic astrophysical flux. We show that a statistically significant excess of events from the galactic plane in present IceCube data would favour models in which the cosmic ray density in the inner galactic region is much larger than its local value, thus bringing relevant information on the cosmic ray radial distribution.

description: Soziale Arbeit hat im zurückliegenden Jahrhundert sowohl eine erhebliche Expansion wie auch Professionalisierung erlebt. Während Soziale Arbeit noch vor einhundert Jahren als karitatives Betätigungsfeld bürgerlicher Frauen galt, handelt es sich dabei heute um eine wissens- und interaktionsintensive Dienstleistungsarbeit. Gleichwohl hat sich arbeitssoziologische Forschung mit diesem Tätigkeitsfeld bisher kaum beschäftigt. Aber auch da, wo Soziale Arbeit in den Mittelpunkt des Forschungsinteresses rückt, sind es zumeist nicht die Beschäftigten selbst und ihre Arbeitsverhältnisse, die in das Blickfeld wissenschaftlicher Betrachtung geraten. Dabei ist gerade dieser Arbeitsbereich auf Grund seiner Mischung von traditionellen Beharrungsstrukturen und innovativen Neuerungen höchst spannend. Diese Forschungslücke gilt es – zumindest in Ansätzen – zu schließen. Im Projekt „Regulierung professioneller Dienstleistungsarbeit zwischen Individualvertrag und Kollektivvereinbarung“ stehen die Ansprüche der Beschäftigten an die Arbeitsorganisation und die Regulierung der Arbeitsverhältnisse im Mittelpunkt. Gefragt wird nach den Ansprüchen von Sozialpädagoginnen und -pädagogen, Sozialarbeitern und Sozialarbeiterinnen z.B. an Arbeitszeiten, soziale Sicherung, eigenverantwortliches Handeln usw. Zudem stellt sich die Frage danach, ob und wie diese Ansprüche gestaltet werden.

description: We investigate the ground state properties of $\mathrm{Na_2IrO_3}$ based on numerical calculations of the recently proposed {\it ab initio} Hamiltonian represented by Kitaev and extended Heisenberg interactions. To overcome the limitation posed by small tractable system sizes in the exact diagonalization study employed in a previous study (Yamaji $\textit{et al.}$, Phys. Rev. Lett. $\textbf{113}$, 107201 (2014)), we apply two-dimensional density matrix renomalization group, and infinite-size tensor-network method. By calculating at much larger system sizes, we critically test the validity of the exact diagonalization results. The results consistently indicate that the ground state of $\mathrm{Na_2IrO_3}$ is a magnetically ordered state with zigzag configuration in agreement with experimental observations and the previous diagonalization study. Applications of the two independent methods in addition to the exact diagonalization study further uncover a consistent and rich phase diagram near the zigzag phase beyond the accessibility of the exact diagonalization. For example, in the parameter space away from the $\textit{ab initio}$ value of $\mathrm{Na_2IrO_3}$ controlled by the trigonal distortion, we find three phases: (i) an ordered phase with the magnetic moment aligned mutually in $120$ degrees orientation on every third hexagon, (ii) a magnetically ordered phase with a $16$-site unit-cell, and (iii) an ordered phase with presumably incommensurate periodicity of the moment. It suggests that potentially rich magnetic structures may appear in $A_\mathrm{2}\mathrm{IrO_3}$ compounds for $A$ other than Na. The present results also serve to establish the accuracy of the first-principles approach in reproducing the available experimental results thereby further contribute to find a route to realize the Kitaev spin liquid.

description: Given a hyperbolic knot $K$ and any $n\geq 2$ the abelian representations and the holonomy representation each give rise to an $(n-1)$-dimensional component in the $\operatorname{SL}(n,\Bbb{C})$-character variety. A component of the $\operatorname{SL}(n,\Bbb{C})$-character variety of dimension $\geq n$ is called high-dimensional. It was proved by Cooper and Long that there exist hyperbolic knots with high-dimensional components in the $\operatorname{SL}(2,\Bbb{C})$-character variety. We show that given any non-trivial knot $K$ and sufficiently large $n$ the $\operatorname{SL}(n,\Bbb{C})$-character variety of $K$ admits high-dimensional components.

Alongside sophisticated sensors, UAVs can be equipped with communication adaptors aimed for inter-UAV communication. Inter-communication of UAVs to form a UAV swarm raises questions on how to manage its communication structure and mobility. In this paper, we consider therefore the problem of establishing an efficient swarm movement model and a network topology between a collection of UAVs, which are specifically deployed for the scenario of high-quality forest-mapping. The forest environment with its highly heterogeneous distribution of trees and obstacles represents an extreme challenge for a UAV swarm. It requires the swarm to constantly avoid possible collisions with trees, to change autonomously the trajectory, which can lead to disconnection to the swarm, and to reconnect to the swarm after passing the obstacle, while continue collecting environmental data that needs to be fused and assessed efficiently. In this paper, we propose a novel solution to the formation flight problem for UAV swarms. The proposed method provides an adaptive and reliable network structure, which maintains swarm connectivity and communicability. These characteristics are needed to achieve a detailed and accurate description of the environment from the data acquired by the UAV swarm. The main characteristics of our approach are high scalability regarding the number of UAVs in the swarm and the adaptive network topology within the swarm.

spreading RDM

description: The objective of the German non-profit association NFDI (German short
 form for ”National Research Data Infrastructure”) is to make the data stock of the entire
 German science system accessible to the public. To do so, it should involve all stake-
 holders. However, currently the Universities of Applied Sciences (UAS) are underre-
 presented in the NFDI, and there is a danger of neglecting their needs. Therefore, we
 present the project ”Research Data Management at Universities of Applied Sciences
 in the State of Rhineland-Palatinate” (FDM@HAW.rlp), which is funded by the German
 Federal Ministry of Education and Research (BMBF) and financed within the Recov-
 ery and Resilience Facility of the European Union. In the project, seven public UAS
 in Rhineland-Palatinate and the Catholic University of Applied Sciences (CUAS) Mainz
 follow a common goal: They intend to establish an institutional RDM within a period of
 three years by building up competencies at the UAS, setting up services for researchers
 and finding solutions for a common technical infrastructure.

description: The nematic twist-bend (TB) phase, exhibited by certain achiral thermotropic liquid crystalline (LC) dimers, features a nanometer-scale, heliconical rotation of the average molecular long axis (director) with equally probable left- and right-handed domains. On meso to macroscopic scales, the TB phase may be considered as a stack of equivalent slabs or "pseudo-layers", each one helical pitch in thickness. The long wavelength fluctuation modes should then be analogous to those of a smectic-A phase, and in particular the hydrodynamic mode combining "layer" compression and bending ought to be characterized by an effective layer compression elastic constant $B_{eff}$ and average director splay constant $K_1^{eff}$. The magnitude of $K_1^{eff}$ is expected to be similar to the splay constant of an ordinary nematic LC, but due to the absence of a true mass density wave, $B_{eff}$ could differ substantially from the typical value of $\sim 10^6$ Pa in a conventional smectic-A. Here we report the results of a dynamic light scattering study, which confirms the "pseudo-layer" structure of the TB phase with $B_{eff}$ in the range $\sim 10^3-10^4$ Pa. We show additionally that the temperature dependence of $B_{eff}$ at the TB to nematic transition is accurately described by a coarse-grained free energy density, which is based on a Landau-deGennes expansion in terms of a heli-polar order parameter that characterizes the TB state and is linearly coupled to bend distortion of the director.

description: We develop a computationally inexpensive model to examine the dynamics of boson-assisted electron relaxation in solids, studying nonequilibrium dynamics in a metal, in a nodal superconductor with a stationary density of states, and in a nodal superconductor where the gap dynamically opens. In the metallic system, the electron population resembles a thermal population at all times, but the presence of even a fixed nodal gap both invalidates a purely thermal treatment and sharply curtails relaxation rates. For a gap that is allowed to open as electron relaxation proceeds, effects are even more pronounced, and gap dynamics become coupled to the dynamics of the electron population. Comparisons to experiments reveal that phase-space restrictions in the presence of a gap are likely to play a significant role in the widespread observation of coexisting femtosecond and picosecond dynamics in the cuprate high-temperature superconductors.

description: Seaports form part of economic and logistics systems which are in a profound transformation. The global market place with its powerful players, extensive business networks and complex logistics systems have a dramatic impact on seaports. Mainly the logistics environment creates a high degree on uncertainty and leaves European port managers puzzled with the question how to respond effectively to market dynamics. Port authorities and port management teams are forced to re-assess role and to specify competencies that should lead to competitive advantage and should position the port for growth.

description: The complex electronic properties of $\mathrm{ZrTe_5}$ have recently stimulated in-depth investigations that assigned this material to either a topological insulator or a 3D Dirac semimetal phase. Here we report a comprehensive experimental and theoretical study of both electronic and structural properties of $\mathrm{ZrTe_5}$, revealing that the bulk material is a strong topological insulator (STI). By means of angle-resolved photoelectron spectroscopy, we identify at the top of the valence band both a surface and a bulk state. The dispersion of these bands is well captured by ab initio calculations for the STI case, for the specific interlayer distance measured in our x-ray diffraction study. Furthermore, these findings are supported by scanning tunneling spectroscopy revealing the metallic character of the sample surface, thus confirming the strong topological nature of $\mathrm{ZrTe_5}$.

Arbeitsregulierung als transnationaler Governanceprozess : Lehren aus dem NAFTA-Raum

Subjects: subject: Arbeitspolitik
subject: 320

description: In den letzten Jahrzehnten sind nicht nur vielfältige internationale Institutionen zur Regelung von Problemen und Konflikten entstanden, die sich aus den Globalisierungsprozessen herleiten. Auch haben sich die Akteurskonstellationen erweitert und schließen nicht-staatliche Akteure ein. Dies alles hat in zahlreichen Politikfeldern Formen transnationaler Governance hervorgebracht. Doch trotz deren Heterogenität überwiegen in der politikwissenschaftlichen Forschung politikfeldunspezifische und häufig auch normativ und institutionell-fixierte Ansätze. Nach einer Skizze einiger Aporien der theoretischen Diskussion werden wir dieses Problem am Beispiel des Konfliktfelds internationaler Arbeitsregulierung behandeln. Empirischer Bezugspunkt ist die Wirkungsanalyse des `North American Agreement on Labor Cooperation´ - es ist dies ein junges Arbeitsregime, das 1994 als Nebenabkommen zum nordamerikanischen Freihandelsvertrag in Kraft trat. Die Untersuchung zeigt, dass die strukturellen und institutionellen Eigensinnigkeiten der politischen Mehrebenenprozesse internationale Arbeitsregulierung als Konfliktfeld in spezifischer Weise strukturieren. Notwendig für eine umfassende Analyse internationaler Arbeitsregulierung, so die zentrale These, ist die Entwicklung eines politik- und konfliktfeldspezifischen Zugangs zu den transnationalen Governance-Prozessen, der es erst ermöglicht, komplexe innergesellschaftliche Widersprüche und Dynamiken und schließlich deren Widerspenstigkeit gegenüber internationalen Beziehungen zu erfassen.

description: Let $n$ be a nonzero integer. A set of $m$ positive integers is called a $D(n)$-$m$-tuple if the product of any two of its distinct elements increased by $n$ is a perfect square. Let $k$ be a positive integer. By elementary means, we show that the $D(-8k^2)$-pair $\{8k^2, 8k^2+1\}$ can be extended to at most a quadruple (the third and fourth element can only be $1$ and $32k^2+1$). At the end, we suggest considering a $D(-k^2)$-triple $\{ 1, 2k^2, 2k^2+2k+1\}$ as possible future research direction.
