description: We present the new MSHT20 set of parton distribution functions (PDFs) of the proton, determined from global analyses of the available hard scattering data. The PDFs are made available at NNLO, NLO, and LO, and supersede the MMHT14 sets. They are obtained using the same basic framework, but the parameterisation is now adapted and extended, and there are 32 pairs of eigenvector PDFs. We also include a large number of new data sets: from the final HERA combined data on total and heavy flavour structure functions, to final Tevatron data, and in particular a significant number of new LHC 7 and 8 TeV data sets on vector boson production, inclusive jets and top quark distributions. We include up to NNLO QCD corrections for all data sets that play a major role in the fit, and NLO EW corrections where relevant. We find that these updates have an important impact on the PDFs, and for the first time the NNLO fit is strongly favoured over the NLO, reflecting the wider range and in particular increased precision of data included in the fit. There are some changes to central values and a significant reduction in the uncertainties of the PDFs in many, though not all, cases. Nonetheless, the PDFs and the resulting predictions are generally within one standard deviation of the MMHT14 results. The major changes are the $u-d$ valence quark difference at small $x$, due to the improved parameterisation and new precise data, the $\bar d, \bar u$ difference at small $x$, due to a much improved parameterisation, and the strange quark PDF due to the effect of LHC $W,Z$ data and inclusion of new NNLO corrections for dimuon production in neutrino DIS. We discuss the phenomenological impact of our results, and in general find reduced uncertainties in predictions for processes such as Higgs, top quark pair and $W,Z$ production at post LHC Run-II energies.

description: We consider a Stark Hamiltonian on a two-dimensional bounded domain with Dirichlet boundary conditions. In the strong electric field limit we derive, under certain local convexity conditions, a three-term asymptotic expansion of the low-lying eigenvalues. This shows that the excitation frequencies are proportional to the square root of the boundary curvature at a certain point determined by the direction of the electric field.

description: Quantum dots (QDs) made from semiconductors are among the most promising platforms for the developments of quantum computing and simulation chips, and have advantages over other platforms in high density integration and in compatibility to the standard semiconductor chip fabrication technology. However, development of a highly tunable semiconductor multiple QD system still remains as a major challenge. Here, we demonstrate realization of a highly tunable linear quadruple QD (QQD) in a narrow bandgap semiconductor InAs nanowire with fine finger gate technique. The QQD is studied by electron transport measurements in the linear response regime. Characteristic two-dimensional charge stability diagrams containing four groups of resonant current lines of different slopes are found for the QQD. It is shown that these current lines can be individually assigned as arising from resonant electron transport through the energy levels of different QDs. Benefited from the excellent gate tunability, we also demonstrate tuning of the QQD to regimes where the energy levels of two QDs, three QDs and all the four QDs are energetically on resonance, respectively, with the fermi level of source and drain contacts. A capacitance network model is developed for the linear QQD and the simulated charge stability diagrams based on the model show good agreements with the experiments. Our work presents a solid experimental evidence that narrow bandgap semiconductor nanowires multiple QDs could be used as a versatile platform to achieve integrated qubits for quantum computing and to perform quantum simulations for complex many-body systems.

description: We study the magnetic field evolution of an isolated spiral galaxy, using isolated Milky Way-mass galaxy formation simulations and a novel prescription for magnetohydrodynamic (MHD) supernova feedback. Our main result is that a galactic dynamo can be seeded and driven by supernova explosions, resulting in magnetic fields whose strength and morphology is consistent with observations. In our model, supernovae supply thermal energy, and a low level magnetic field along with their ejecta. The thermal expansion drives turbulence, which serves a dual role by efficiently mixing the magnetic field into the interstellar medium, and amplifying it by means of turbulent dynamo. The computational prescription for MHD supernova feedback has been implemented within the publicly available ENZO code, and is fully described in this paper. This improves upon ENZO's existing modules for hydrodynamic feedback from stars and active galaxies. We find that the field attains $μG$-levels over Gyr-time scales throughout the disk. The field also develops large-scale structure, which appears to be correlated with the disk's spiral arm density structure. We find that seeding of the galactic dynamo by supernova ejecta predicts a persistent correlation between gas metallicity and magnetic field strength. We also generate all-sky maps of the Faraday rotation measure from the simulation-predicted magnetic field, and present a direct comparison with observations.

Anisotopic inflation with a non-abelian gauge field in Gauss-Bonnet gravity

Year: 2016
Subjects: subject: High Energy Physics - Theory (hep-th)

description: In presence of Gauss-Bonnet corrections, we study anisotropic inflation aided by a massless $SU(2)$ gauge field where both the gauge field and the Gauss-Bonnet term are non-minimally coupled to the inflaton. In this scenario, under slow-roll approximations, the anisotropic inflation is realized as an attractor solution with quadratic forms of inflaton potential and Gauss-Bonnet coupling function. We show that the degree of anisotropy is proportional to the additive combination of two slow-roll parameters of the theory. The anisotropy may become either positive or negative similar to the non-Gauss-Bonnet framework, a feature of the model for anisotropic inflation supported by a non-abelian gauge field but the effect of Gauss-Bonnet term further enhances or suppresses the generated anisotropy.

description: The computational discovery and design of zeolites is a crucial part of the chemical industry. Finding highly accurate while computationally feasible protocol for identification of hypothetical zeolites that could be targeted experimentally is a great challenge. To tackle the challenge, we trained neural network potentials (NNP) with the SchNet architecture on a structurally diverse database of density functional theory (DFT) data. This database was iteratively extended by active learning to cover not only low-energy equilibrium configurations but also high-energy transition states. We demonstrate that the resulting reactive NNPs retain the accuracy of the DFT reference for thermodynamic stabilities, vibrational properties, and reactive and non-reactive phase transformations. The novel NNPs outperforms specialized, analytical force fields for silica, such as ReaxFF, by order(s) of magnitude in accuracy, while speeding up the calculations in comparison to DFT by at least three orders of magnitude. As a showcase, we screened an existing zeolite database containing 330 thousand structures and revealed more than 20 thousand additional hypothetical frameworks in the thermodynamically accessible range of zeolite synthesis. Hence, our NNPs are expected to be essential for future high-throughput studies on the structure and reactivity of hypothetical and existing zeolites.

description: Τις τελευταίες δεκαετίες, υπάρχει μια ραγδαία αύξηση των νέων συνθετικών οπιοειδών. Αυτές οι ουσίες συχνά πωλούνται στο διαδίκτυο με την ονομασία “ χημικά έρευνας”, “ άλατα μπάνιου”, ¨φυσικά τονωτικά” και είναι σχεδιασμένες έτσι ώστε να μιμούνται τις ιδιότητες των ψυχοτρόπων ουσιών, προκαλώντας εξάρτηση. Συχνά συναντώνται και ως νοθεία σε ήδη υπάρχουσα ναρκωτικά όπως η ηρωίνη, καθιστώντας δύσκολο τον άμεσο εντοπισμό τους. Για τον λόγο αυτό, αποτελούν σοβαρό κίνδυνο για την δημόσια υγεία. Δεδομένου των καταγεγραμμένων θανάτων που σχετίζονται με τα συνθετικά οπιοειδή, αποτελεί επείγουσα ανάγκη η ανίχνευση αυτών των ενώσεων σε βιολογικά δείγματα , με σκοπό την εύρεση αποτελεσματικών θεραπειών και την αντιμετώπιση της αναπνευστικής καταστολής που προκαλείται από αυτές, αλλά και τον έλεγχο τους σε επίπεδο κοινωνίας. Συνεπώς, η αναλυτική ταυτοποίηση αυτών των ουσιών σε βιολογικά δείγματα είναι υψίστης σημασίας. Οι κύριες μέθοδοι ανάλυσης που χρησιμοποιούνται για την ταυτοποίηση των συνθετικών οπιοειδών είναι η αέρια χρωματογραφία συζευγμένη με φασματομετρία μάζας (GC-MS) καθώς και η υγρή χρωματογραφία συζευγμένη με φασματομερία μάζας ,συνήθως σε σειρά ,(LC-MS/MS), αλλά και άλλες πιο σύγχρονες τεχνικές βασισμένες στην υγρή χρωματογραφία ( LC-TOF, UHPLC, HILC)
description: Over the few decades, there is an emerging increase of new synthetic opioids. These substances are often sold via internet and are usually mentioned as “research chemicals”, “ bath salts”, “ herbal highs” and they are designed to mimic the effects of psychoactive substances, causing abuse. There are often present as adulteration in other drugs, such such heroin, making difficult their immediate identification. That’s why, the represent an alarming threat to public health. Given the wide number of fatalities related to these compounds, it is an urgent need to identify them in biological samples, in order to administer an effective treatment and reverse the respiratory depression caused by opioid related substances, as well as their control in the society. Consequently, the analytical identification of these substances in biological matrices is of utmost importance. The major analytical techniques used for the identification of novel synthetic opioids are gas chromatography coupled with mass spectrometry (GS-MS) and liquid chromatography coupled with tandem mass spectrometry, (LC-MS/MS), and other modern techniques based in liquid chromatography as well (LC-TOF, UHPLC, HILC).

description: We give an explicit toy qubit transport model for transferring information from the gravitational field of a black hole to the Hawking radiation by a continuous unitary transformation of the outgoing radiation and the black hole gravitational field. The model has no firewalls or other drama at the event horizon, and it avoids a counterargument that has been raised for subsystem transfer models as resolutions of the firewall paradox. Furthermore, it fits the set of six physical constraints that Giddings has proposed for models of black hole evaporation. It does utilize nonlocal qubits for the gravitational field but assumes that the radiation interacts locally with these nonlocal qubits, so in some sense the nonlocality is confined to the gravitational sector. Although the qubit model is too crude to be quantitively correct for the detailed spectrum of Hawking radiation, it fits qualitatively with what is expected.

description: We study the one-dimensional asymmetric simple exclusion process on the lattice $\{1, \dots,N\}$ with creation/annihilation at the boundaries. The boundary rates are time dependent and change on a slow time scale $N^{-a}$ with $a>0$. We prove that at the time scale $N^{1+a}$ the system evolves quasi-statically with a macroscopic density profile given by the entropy solution of the stationary Burgers equation with boundary densities changing in time, determined by the corresponding microscopic boundary rates. We consider two different types of boundary rates: the "Liggett boundaries" that correspond to the projection of the infinite dynamics, and the reversible boundaries, that correspond to the contact with particle reservoirs in equilibrium. The proof is based on the control of the Lax boundary entropy--entropy flux pairs and a coupling argument.

description: The detailed characterization of non-trivial coherence properties of composite quantum systems of increasing size is an indispensable prerequisite for scalable quantum computation, as well as for understanding of nonequilibrium many-body physics. Here we show how autocorrelation functions in an interacting system of phonons as well as the quantum discord between distinct degrees of freedoms can be extracted from a small controllable part of the system. As a benchmark, we show this in chains of up to 42 trapped ions, by tracing a single phonon excitation through interferometric measurements of only a single ion in the chain. We observe the spreading and partial refocusing of the excitation in the chain, even on a background of thermal excitations. We further show how this local observable reflects the dynamical evolution of quantum discord between the electronic state and the vibrational degrees of freedom of the probe ion.

Magnetoelectric coupling in superconductor-helimagnet heterostructures

description: The Ginzburg-Landau free energy of a conventional superconductor coupled to a helimagnet is microscopically derived using functional field integral techniques. We show that the spin texture leads to a Lifshitz invariant in the free energy, which couples the momentum density of the superconducting condensate to the magnetization of the helimagnet. For helimagnets with a conical texture, the Lifshitz invariant yields a spatial modulation of the superconducting phase along the helical wavevector of the magnetic texture. Based on self-consistent numerical calculations, we verify the theoretical formalism by investigating a superconductor that contains a helical Yu-Shiba-Rusinov (YSR) chain. We demonstrate that the texture-induced magnetoelectric coupling produces a strong supercurrent along the YSR chain, which induces a detectable magnetic field.

description: We are concerned with the dependence of the lowest positive eigenvalue of the Dirac operator on the geometry of rectangles, subject to infinite-mass boundary conditions. We conjecture that the square is a global minimiser both under the area or perimeter constraints. Contrary to well-known non-relativistic analogues, we show that the present spectral problem does not admit explicit solutions. We prove partial optimisation results based on a variational reformulation and newly established lower and upper bounds to the Dirac eigenvalue. We also propose an alternative approach based on symmetries of rectangles and a non-convex minimisation problem; this implies a sufficient condition formulated in terms of a symmetry of the minimiser which guarantees the conjectured results.

Stellar Helium Burning in Other Universes: A solution to the triple alpha fine-tuning problem

description: Motivated by the possible existence of other universes, with different values for the fundamental constants, this paper considers stellar models in universes where $^8$Be is stable. Many previous authors have noted that stars in our universe would have difficulty producing carbon and other heavy elements in the absence of the well-known $^{12}$C resonance at 7.6 MeV. This resonance is necessary because $^8$Be is unstable in our universe, so that carbon must be produced via the triple alpha reaction to achieve the requisite abundance. Although a moderate change in the energy of the resonance (200 -- 300 keV) will indeed affect carbon production, an even smaller change in the binding energy of beryllium ($\sim100$ keV) would allow $^8$Be to be stable. A stable isotope with $A=8$ would obviate the need for the triple alpha process in general, and the $^{12}$C resonance in particular, for carbon production. This paper explores the possibility that $^8$Be can be stable in other universes. Simple nuclear considerations indicate that bound states can be realized, with binding energy $\sim0.1-1$ MeV, if the fundamental constants vary by a $\sim {\rm few}-10$ percent. In such cases, $^8$Be can be synthesized through helium burning, and $^{12}$C can be produced later through nuclear burning of beryllium. This paper focuses on stellar models that burn helium into beryllium; once the universe in question has a supply of stable beryllium, carbon production can take place during subsequent evolution in the same star or in later stellar generations. Using both a semi-analytic stellar structure model as well as a state-of-the-art stellar evolution code, we find that viable stellar configurations that produce beryllium exist over a wide range of parameter space. Finally, we demonstrate that carbon can be produced during later evolutionary stages.

description: We report on the transport study of a double quantum dot (DQD) device made from a freestanding, single crystalline InSb nanosheet. The freestanding nanosheet is grown by molecular beam epitaxy and the DQD is defined by top gate technique. Through the transport measurements, we demonstrate how a single quantum dot (QD) and a DQD can be defined in an InSb nanosheet by tuning voltages applied to the top gates. We also measure the charge stability diagrams of the DQD and show that the charge states and the inter-dot coupling between the two individual QDs in the DQD can be efficiently regulated by the top gates. Numerical simulations for the potential profile and charge density distribution in the DQD have been performed and the results support the experimental findings and provide a better understanding of fabrication and transport characteristics of the DQD in the InSb nanosheet. The achieved DQD in the two-dimensional InSb nanosheet possesses pronounced benefits in lateral scaling and can thus serve as a new building block for developments of quantum computation and quantum simulation technologies.

description: We prove extension theorems for several geometric properties such as asymptotic property C (APC), finite decomposition complexity (FDC), strict finite decomposition complexity (sFDC) which are weakenings of Gromov's finite asymptotic dimension (FAD). The context of all theorems is a finitely generated group $G$ with a word metric and a coarse quasi-action on a metric space $X$. We assume that the quasi-stabilizers have a property $P_1$, and $X$ has the same or sometimes a weaker property $P_2$. Then $G$ also has property $P_2$. We show some sample applications, discuss constraints to further generalizations, and illustrate the flexibility that the weak quasi-action assumption allows.

description: Die Privatisierung des Unternehmens Deutsche Bahn bringt nicht nur auf struktureller Ebene, sondern auch für die Beschäftigten im Zugbegleitdienst und die Bahnreisenden selbst eine Reihe von Veränderungen mit sich. Neben der traditionellen Rolle des Zugbegleiters als Kontrolleur ist die des Servicemitarbeiters stark in den Vordergrund gerückt. Bahnreisende gelten nicht mehr nur als Bahnbenutzer, sondern als zu bedienende Kunden. Welche Auswirkungen haben die Veränderungen auf die Dienstleistungsinteraktion zwischen beiden? Die Akteure müssen für sich abgleichen, welche Rolle sie in welcher Situation ausfüllen wollen und müssen. Somit ist von beiden Seiten nicht mehr eindeutig vorhersehbar, wie sich ihr Gegenüber während des Dienstleistungskontaktes verhalten wird. Sowohl Zugbegleiter als auch Reisende müssen ihre Rollen in doppelter Weise ausbalancieren.

Flexible Beschäftigungsform "Zeitarbeit" auf dem Prüfstand

description: Zeitarbeit hat sich in Deutschland zur am schnellsten expandierenden Beschäftigungsform entwickelt. Als spezifische Variante atypischer Beschäftigungsverhältnisse ist Zeitarbeit in empirischen Untersuchungen bisher jedoch nur selten analysiert worden. In Anbetracht der Zuwachsrate ist diese Nichtberücksichtigung unverständlich. Die Flexibilisierung von Beschäftigungsformen hat zu einer Verlagerung des "unternehmerischen Risikos" auf den Arbeitnehmer geführt. Die Beschäftigten sind gezwungen, ihre Arbeitskraft immer wieder anzubieten, wodurch sie auf marktfähige Qualifikationen und Kompetenzen angewiesen sind. Die vorliegende Untersuchung fragt nach Voraussetzungen bzw. Bedingungen, welche Zeitarbeit für Qualifizierung und berufliche Kompetenzentwicklung, aber auch für den Erhalt von Gesundheit bereitstellt. Erste empirische Ergebnisse einer vergleichenden Querschnittuntersuchung von Zeitarbeitnehmern und dauerhaft beschäftigten Facharbeitern in der Fertigungsbranche werden zur Diskussion gestellt.

description: Der Beitrag untersucht die Folgen neuartiger, durch die heutige Dynamik der Arbeitsgesellschaft ausgelöste soziale Exklusionseffekte und Spaltungstendenzen. Es geht um neue soziale Verwundungsrisiken und existentielle Gefährdungen unterschiedlicher Gruppen und Populationen. Gefährdet sind solche Personen und Personengruppen, die sich z.B. trotz guter Bildungs- und Berufsvoraussetzungen dauerhaft mit der Erfahrung von Ausgrenzung und Ausschluss konfrontiert sehen. Es entsteht eine neue soziale Grenzziehung zwischen "den Disponiblen" und "den Überflüssigen", die quer zu den alten sozialen Ungleichheiten zwischen oben und unten, Armen und Reichen usw. zu liegen scheint. Der Beitrag analysiert die Bedingungen und Mechanismen dieser sozialen Grenzziehung und interpretiert biographische Verlaufsmuster in die "Überflüssigkeit" als eine ihrer charakteristischen Erscheinungen.

Microscopic formulas for thermoelectric transport coefficients in lattice systems

description: A macroscopic description of thermoelectric phenomena involves several tensorial transport coefficients. Textbook microscopic Kubo formulas for them are plagued with ambiguities in the definitions of the current operators and the magnetization. We derive a version of these formulas for lattice systems which is free from ambiguities but contains additional terms compared to the textbook results. For symmetric components of thermoelectric tensors, we identify a large class of lattice systems for which the additional terms vanish with a natural choice of the energy current. To eliminate ambiguities in the skew-symmetric components, one needs to interpret them as relative quantities: only their differences for pairs of materials are well-defined.

Differential Inequalities in Multi-Agent Coordination and Opinion Dynamics Modeling

description: Distributed algorithms of multi-agent coordination have attracted substantial attention from the research community; the simplest and most thoroughly studied of them are consensus protocols in the form of differential or difference equations over general time-varying weighted graphs. These graphs are usually characterized algebraically by their associated Laplacian matrices. Network algorithms with similar algebraic graph theoretic structures, called being of Laplacian-type in this paper, also arise in other related multi-agent control problems, such as aggregation and containment control, target surrounding, distributed optimization and modeling of opinion evolution in social groups. In spite of their similarities, each of such algorithms has often been studied using separate mathematical techniques. In this paper, a novel approach is offered, allowing a unified and elegant way to examine many Laplacian-type algorithms for multi-agent coordination. This approach is based on the analysis of some differential or difference inequalities that have to be satisfied by the some "outputs" of the agents (e.g. the distances to the desired set in aggregation problems). Although such inequalities may have many unbounded solutions, under natural graphic connectivity conditions all their bounded solutions converge (and even reach consensus), entailing the convergence of the corresponding distributed algorithms. In the theory of differential equations the absence of bounded non-convergent solutions is referred to as the equation's dichotomy. In this paper, we establish the dichotomy criteria of Laplacian-type differential and difference inequalities and show that these criteria enable one to extend a number of recent results, concerned with Laplacian-type algorithms for multi-agent coordination and modeling opinion formation in social groups.

neutrinos

description: The CONUS experiment is located at the nuclear power plant of Brokdorf, Germany, at 17m distance from the reactor core. It aims at detecting coherent elastic neutrino nucleus scattering with four high-purity point contact Germanium detectors with a noise threshold in the range of 300 eV inside an elaborate shield. Proximity to a reactor core requires an in-depth understanding of the neutron background. The thorough characterization of the background with Bonner sphere measurements and a non-shielded Ge spectrometer will be presented and the successful suppression of all reactor-correlated background contributions within the CONUS shield will be shown. The remaining background contributions are examined with the help of Monte Carlo simulations. The special requirements for a detector close to a nuclear power plant will be discussed and the solutions will be presented. In the talk it will be illustrated how these challenges are met for the CONUS experiment. The long-term performance of the detectors and the latest results will be shown. Presented at the 2019 Magnificent CEvNS workshop.

description: We describe solutions to the problem of elementary classification in the class of group algebras of free groups. We will show that unlike free groups, two group algebras of free groups over infinite fields are elementarily equivalent if and only if the groups are isomorphic and the fields are equivalent in the weak second order logic. We will show that the set of all free bases of a free group $F$ is 0-definable in the group algebra $K(F)$ when $K$ is an infinite field, the set of geodesics is definable, and many geometric properties of $F$ are definable in $K(F)$. Therefore $K(F)$ knows some very important information about $F$. We will show that similar results hold for group algebras of limit groups.
