description: We present relativistic analyses of 9257 measurements of times-of-arrival from the first binary pulsar, PSR B1913+16, acquired over the last thirty-five years. The determination of the 'Keplerian' orbital elements plus two relativistic terms completely characterizes the binary system, aside from an unknown rotation about the line of sight; leading to a determination of the masses of the pulsar and its companion: 1.438 $\pm$ 0.001 solar masses and 1.390 $\pm$ 0.001 solar masses, respectively. In addition, the complete system characterization allows the creation of tests of relativistic gravitation by comparing measured and predicted sizes of various relativistic phenomena. We find that the ratio of observed orbital period decrease due to gravitational wave damping (corrected by a kinematic term) to the general relativistic prediction, is 0.9983 pm 0.0016; thereby confirming the existence and strength of gravitational radiation as predicted by general relativity. For the first time in this system, we have also successfully measured the two parameters characterizing the Shapiro gravitational propagation delay, and find that their values are consistent with general relativistic predictions. We have also measured for the first time in any system the relativistic shape correction to the elliptical orbit, $δ_θ$,although its intrinsic value is obscured by currently unquantified pulsar emission beam aberration. We have also marginally measured the time derivative of the projected semimajor axis, which, when improved in combination with beam aberration modelling from geodetic precession observations, should ultimately constrain the pulsar's moment of inertia.

description: OJ 287 is a blazar thought to be a binary system containing a ~ 18 billion solar mass primary black hole accompanied by a ~ 150 million solar mass secondary black hole in an eccentric orbit, which triggers electromagnetic flares twice in every ~ 12 year orbital period when it traverses the accretion disk of the primary. The times of these emissions are consistent with the predictions of general relativity calculated to the 4.5th post-Newtonian order. The orbit of the secondary black hole samples the gravitational field at distances between O(10) and O(50) Schwarzschild radii around the primary, and hence is sensitive to the possible presence of a dark matter spike around it. We find that the agreement of general-relativistic calculations with the measured timings of flares from OJ 287 constrains the mass of such a spike to < 3% of the primary mass.

description: Thermal higgsino dark matter (DM), with mass around 1 TeV, is a well-motivated, minimal DM scenario that arises in supersymmetric extensions of the Standard Model. Higgsinos may naturally be the lightest superpartners in Split-supersymmetry models that decouple the scalar superpartners while keeping higgsinos and gauginos close to the TeV scale. Higgsino DM may annihilate today to give continuum gamma-ray emission at energies less than a TeV in addition to a line-like signature at energies equal to the mass. Previous searches for higgsino DM, for example with the H.E.S.S. gamma-ray telescope, have not reached the necessary sensitivity to probe the higgsino annihilation cross-section. In this work we make use of 14 years of $\textit{Fermi}$ gamma-ray data at energies above $\sim$10 GeV to search for the continuum emission near the Galactic Center from higgsino annihilation. We interpret our results using DM profiles from Milky Way analogue galaxies in the FIRE-2 hydrodynamic cosmological simulations. We set the strongest constraints to-date on higgsino-like DM. Our results show a mild, $\sim$2$σ$ preference for higgsino DM with a mass near the thermal higgsino mass and, depending on the DM density profile, the expected cross-section.

description: We analyse new observations with the International Low Frequency Array (LOFAR) telescope, and archival data from the Multi-Element Radio Linked Interferometer Network (MERLIN) and the Karl G. Jansky Very Large Array (VLA). We model the spatially resolved radio spectrum of Arp 220 from 150 MHz to 33 GHz. We present an image of Arp 220 at 150 MHz with resolution $0.65''\times0.35''$, sensitivity 0.15 mJy beam$^{-1}$, and integrated flux density $394\pm59$ mJy. More than 80% of the detected flux comes from extended ($6''\approx$2.2 kpc) steep spectrum ($α=-0.7$) emission, likely from star formation in the molecular disk surrounding the two nuclei. We find elongated features extending $0.3''$ (110 pc) and $0.9''$ (330 pc) from the eastern and western nucleus respectively, which we interpret as evidence for outflows. The extent of radio emission requires acceleration of cosmic rays far outside the nuclei. We find that a simple three component model can explain most of the observed radio spectrum of the galaxy. When accounting for absorption at 1.4 GHz, Arp 220 follows the FIR/radio correlation with $q=2.36$, and we estimate a star formation rate of 220 M$_\odot\text{yr}^{-1}$. We derive thermal fractions at 1 GHz of less than 1% for the nuclei, which indicates that a major part of the UV-photons are absorbed by dust. International LOFAR observations shows great promise to detect steep spectrum outflows and probe regions of thermal absorption. However, in LIRGs the emission detected at 150 MHz does not necessarily come from the main regions of star formation. This implies that high spatial resolution is crucial for accurate estimates of star formation rates for such galaxies at 150 MHz.

description: Laser beam scanning is central to many applications, including displays, microscopy, three-dimensional mapping, and quantum information. Reducing the scanners to microchip form factors has spurred the development of very-large-scale photonic integrated circuits of optical phased arrays and focal plane switched arrays. An outstanding challenge remains to simultaneously achieve a compact footprint, broad wavelength operation, and low power consumption. Here, we introduce a laser beam scanner that meets these requirements. Using microcantilevers embedded with silicon nitride nanophotonic circuitry, we demonstrate broadband, one- and two-dimensional steering of light with wavelengths from 410 nm to 700 nm. The microcantilevers have ultracompact ~0.1 mm$^2$ areas, consume ~31 to 46 mW of power, are simple to control, and emit a single light beam. The microcantilevers are monolithically integrated in an active photonic platform on 200-mm silicon wafers. The microcantilever-integrated photonic circuits miniaturize and simplify light projectors to enable versatile, power-efficient, and broadband laser scanner microchips.

description: Any matrix product state $|Ψ\rangle$ has a set of associated kept and discarded spaces, needed for the description of $|Ψ\rangle$, and changes thereof, respectively. These induce a partition of the full Hilbert space of the system into mutually orthogonal spaces of irreducible $n$-site variations of $|Ψ\rangle$. Here, we introduce a convenient projector formalism and diagrammatic notation to characterize these $n$-site spaces explicitly. This greatly facilitates the formulation of MPS algorithms that explicitly or implicitly employ discarded spaces. As an illustration, we derive an explicit expression for the $n$-site energy variance and evaluate it numerically for a model with long-range hopping. We also describe an efficient algorithm for computing low-lying $n$-site excitations above a finite MPS ground state.

description: We study information theoretic quantities in models with three and four spin interactions. These models show distinctive characteristics compared to their nearest neighbour counterparts. Here, we quantify these in terms of the Nielsen complexity in static and quench scenarios, the Fubini-Study complexity, and the entanglement entropy. The models that we study have a rich phase structure, and we show how the difference in the nature of phase transitions in these, compared to ones with nearest neighbour interactions, result in different behaviour of information theoretic quantities, from ones known in the literature. For example, the derivative of the Nielsen complexity does not diverge but shows a discontinuity near continuous phase transitions, and the Fubini-Study complexity may be regular and continuous across such transitions. The entanglement entropy shows a novel discontinuity both at first and second order quantum phase transitions. We also study multiple quench scenarios in these models and contrast these with quenches in the transverse XY model.

description: Using one-dimensional spin-1/2 systems as prototypes of quantum many-body systems, we study the emergence of quantum chaos. The main purpose of this work is to answer the following question: how does the spin-orbit interaction, as a pure quantum interaction, may lead to the onset of quantum chaos? We consider three integrable spin-1/2 systems: the Ising, the XX, and the XXZ limits, and analyze whether quantum chaos develops or not after the addition of the Dzyaloshinskii-Moriya interaction. We find that, depending on the strength of the anisotropy parameter, the answer is positive for the XXZ and Ising models, while no such evidence is observed for the XX model. We also discuss the relationship between quantum chaos and thermalization.

Dipole polarizabilities of light pseudoscalar mesons within the Domain Model of QCD vacuum

Year: 2022

description: Dipole polarizabilities of light pseudoscalar mesons are calculated in the framework of the mean field approach to QCD vacuum and bosonization based on the statistical ensemble of almost everywhere homogeneous Abelian (anti-)self-dual gluon fields -- the domain model of QCD vacuum. In this approach, one derives a nonlocal effective action of meson fields which describes two-point correlation functions and all possible strong, weak and electromagnetic interactions of meson fields including their excited states. Specifically, the role of intermediate scalar meson fields in formation of the polarizabilities is addressed. Within the domain model, the propagators of scalar meson fields composed of light quark-anti-quark pairs have no poles at real momenta. It turns out that for charged pions and kaons, the contribution of intermediate scalar fields to polarizability is substantial, but not the largest one. The calculated polarizabilities are in reasonable agreement with COMPASS experimental data and results of Chiral Perturbation Theory.

description: The axion-nucleon coupling enables the production of axions through the decay of excited ${}^{57}\textrm{Fe}$ isotopes, and axions produced in the Sun through this process are often a target of helioscope searches. We show for the first time that hot, highly magnetic white dwarfs such as ZTF J1901+1458 are a viable target to search for the X-ray signature of axions that were produced by the ${}^{57}\textrm{Fe}$ transition in the core and then converted to photons in the magnetosphere. We calculate that a 100 ks observation of ZTF J1901+1458 with NuSTAR would constrain the coupling of axions to nucleons and photons at a level below the bounds of both current and future planned helioscopes.

description: The quality of ontologies in terms of their correctness and completeness is crucial for developing high-quality ontology-based applications. Traditional debugging techniques repair ontologies by removing unwanted axioms, but may thereby remove consequences that are correct in the domain of the ontology. In this paper we propose an interactive approach to mitigate this for $\mathcal{EL}$ ontologies by axiom weakening and completing. We present algorithms for weakening and completing and present the first approach for repairing that takes into account removing, weakening and completing. We show different combination strategies, discuss the influence on the final ontologies and show experimental results. We show that previous work has only considered special cases and that there is a trade-off between the amount of validation work for a domain expert and the quality of the ontology in terms of correctness and completeness.

description: The interplay between plasma turbulence and magnetic reconnection remains an unsettled question in astrophysical and laboratory plasmas. Here we report the first observational evidence that magnetic reconnection drives subion scale turbulence in magnetospheric plasmas by transferring energy to small scales. We employ a spatial coarse-grained model of Hall magnetohydrodynamics, enabling us to measure the nonlinear energy transfer rate across scale $\ell$ at position $x$. Its application to Magnetospheric Multiscale mission data shows that magnetic reconnection drives intense energy transfer to subion scales. This observational evidence is remarkably supported by the results from Hybrid Vlasov-Maxwell simulations of turbulence to which the coarse-grained model is also applied. These results can potentially answer some open questions on plasma turbulence in planetary environments.

Criteria For Superfluid Instabilities of Geometries with Hyperscaling Violation

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

description: We examine the onset of superfluid instabilities for geometries that exhibit hyperscaling violation and Lifshitz-like scaling at infrared and intermediate energy scales, and approach AdS in the ultraviolet. In particular, we are interested in the role of a non-trivial coupling between the neutral scalar supporting the scaling regime, and the (charged) complex scalar which condenses. The analysis focuses exclusively on unstable modes arising from the hyperscaling-violating portion of the geometry. Working at zero temperature, we identify simple analytical criteria for the presence of scalar instabilities, and discuss under which conditions a minimal charge will be needed to trigger a transition. Finite temperature examples are constructed numerically for a few illustrative cases.

New agegraphic dark energy in Brans-Dicke theory with logarithmic form of scalar field

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In a very recent paper, the current authors (arXiv:gr-qc/1609.01477) have proposed and analyzed in detail the logarithmic form of Brans-Dicke scalar field $ϕ$ as $ϕ\propto ln(α+βa)$, where $α$ and $β$ are positive constants, to alleviate the problems of interacting holographic dark energy models in Brans-Dicke theory. In this paper, the cosmological evolution of a new agegraphic dark energy (NADE) model within the framework of Friedmann-Robertson-Walker Universe is analyzed with the same form of scalar field in Brans-Dicke theory. We derive the equation of state parameter $w_D$ and deceleration parameter $q$ of NADE model. It is observed that $w_D\rightarrow -1$ when $a\rightarrow \infty$, i.e., the NADE mimics cosmological constant in the late time evolution. Indeed, due to the assumption of logarithmic form of Brans-Dicke scalar field the NADE in Brans-Dicke theory behaves like NADE in general relativity in the late time evolution. The NADE model shows a phase transition from matter dominated phase in early time to accelerated phase in late time. We further extend NADE model by including the interaction between dark matter and NADE. In this case, $w_D$ definitely crosses the phantom divide line ($w_D=-1$) in the late time evolution. The phase transition from matter dominated to NADE dominated phase may be achieved at early stage in interacting model. Further, we show that the interacting NADE model resolves the cosmic coincidence problem as the energy density ratio may evolve sufficiently slow at present.

Semiconductor bandgap engineering

description: Developing a semiconductor platform with strong second-order optical nonlinearity can enable better integration with semiconductor photonics and improved performance compared to traditional nonlinear optical materials (i.e. LiNbO₃). In a coupled quantum well structure, the quantum well thicknesses, tunneling barrier thickness, material compositions, and other parameters can be designed to tune the second-order susceptibility, χ⁽²⁾. Utilizing interband transitions allows access to energy level transitions across the bandgap, thus enabling strong, tunable χ⁽²⁾ in the near-IR. Schrodinger-Poisson methods and density functional theory were used to calculate the second-harmonic generation χ⁽²⁾ for GaAs/AlGaAs coupled quantum well structures. By using rigorous wavefunction calculation methods and considering all possible transitions contributing to second-harmonic generation, multiple methods to enhance and tailor χ⁽²⁾ have been determined. Using coupled asymmetric GaAs/AlGaAs quantum wells and varying the quantum well thicknesses, the 50 meV off-resonant wavelength for χ⁽²⁾ can be tuned across the optical communications wavelengths between 1.5 m and 1.7 m. This work lays the foundation for designing III-V superlattices and digital alloys with enhanced second-order optical nonlinearities that can be tailored for the wavelength requirements of particular applications

‘Seven Sages’ in Comparative Folk Narrative Research

description: The present contribution considers the ‘Seven Sages’ from the perspective of comparative folk narrative research. It surveys the history of how the tales embedded in versions of the ‘Seven Sages’ were assessed in Victor Chauvin’s ‘Bibliographie’, Stith Thompson’s ‘Motif-Index’, and in the international tale-type index compiled by Antti Aarne as revised by Thompson and Hans-Jörg Uther. Whereas the Latin denominations for the tales embedded in versions of the ‘Seven Sages’ that are often employed in research derive from and mainly relate to European tradition, the concept of tale types widens the discussion to assess the tales in international tradition, thus documenting their long-lasting impact, whether as part of the ‘Seven Sages’ or as independently performed narratives.

Ẓahīrī of Samarqand’s ‘Sindbādnāma’

description: It is now more than sixty years since Ben E. Perry published his groundbreaking studies on the ‘Sindbādnāma’ in an essay entitled ‘The Origin of the Book of Sindbad’ (1960), in which he surveyed and discussed the vast literature about the genesis and dissemination of this book. Since then, the book’s Oriental career, from its inception in pre-Islamic Iran to its amazing world journey in the form of mediaeval European translations, adaptation, transformations, or imitations, remains still at the stage where Perry left it. The Persian and Arabic versions of the book have not received the kind of attention that a comparative study of an exemplary sample of world literature of this magnitude entails. Just to narrow the gap in the division between ‘the West’ and ‘the Rest’, I propose to look briefly at the contents of Ẓahīrī of Samarqand’s Persian ‘Sindbādnāma’ (written c. 1161) not as a misogynistic text but, rather, as a ‘mirror for princes’.

description: Data analysis of the next generation effective antineutrino mass measurement experiment KATRIN requires reliable knowledge of systematic corrections. In particular, the width of the daughter molecular ion excitation spectrum rovibrational band should be known with a better then 1% precision. Very precise ab initio quantum calculations exist, and we compare them with the well known tritium molecule parameters within the framework of a phenomenological model. The rovibrational band width with accuracy of a few percent is interpreted as a result of the zero-point atomic oscillation in the harmonic potential. The Morse interatomic potential is used to investigate the impact of anharmonic atomic oscillations. The calculated corrections cannot account for the difference between the ab initio quantum calculations and the phenomenological model.

description: This paper conducts a quantitative and contextual analysis of the verbs describing verbal, cognitive, and legal activities in the narrative frame of two early versions of the ‘Seven Sages’: Michael Andreopoulos’ Greek ‘Book of Syntipas’ and the Syriac ‘History of Sindban’. Since speaking, arguing, discussing, persuading, introducing stories, drawing conclusions, and asking questions are the major activities performed by the protagonists, such analysis provides valuable insights into how these two texts tap into pre-existing narrative conventions and discursive patterns in the Greek and Syriac literary traditions, specifically into a judicial interest in Greek literature. The paper in this way contributes to the study of frame narratives and the textualisation of traditional storytelling in the Middle Ages, the history of Greco-Syriac cultural exchange, and gender roles in these two texts.

description: We have carried out $^{63,65}$Cu NMR spectra measurements in magnetic field up to about 45~T on single crystal of a multiferroic triangular antiferromagnet CuCrO$_2$. The measurements were performed for magnetic fields aligned along the crystal $c$-axis. Field and temperature evolution of the spectral shape demonstrates a number of phase transitions. It was found that the 3D magnetic ordering takes place in the low field range ($H\lesssim15$~T). At higher fields magnetic structures form within individual triangular planes whereas the spin directions of the magnetic ions from neighboring planes are not correlated. It is established that the 2D-3D transition is hysteretic in field and temperature. Lineshape analysis reveals several possible magnetic structures existing within individual planes for different phases of CuCrO$_2$. Within certain regions on the magnetic H-T phase diagram of CuCrO$_2$ a 3D magnetic ordering with tensor order parameter is expected.

description: Mogami introduced in 1995 a large class of triangulated 3-dimensional pseudomanifolds, henceforth called "Mogami pseudomanifolds". He proved an exponential bound for the size of this class in terms of the number of tetrahedra. The question of whether all 3-balls are Mogami has remained open since, a positive answer would imply a much-desired exponential upper bound for the total number of 3-balls (and 3-spheres) with N tetrahedra. Here we provide a negative answer: many 3-balls are not Mogami. On the way to this result, we characterize the Mogami property in terms of nuclei, in the sense of Collet-Eckmann-Younan: "The only three-dimensional Mogami nucleus is the tetrahedron".

Every Narrator Is Biased

Publisher: name: Das Mittelalter. Perspektiven mediävistischer Forschung
Year: 2023

description: This article demonstrates that a German-lan­guage verse version of ‘The Seven Sages’ from the first half of the 15th century, entitled ‘Of the Seven Masters’, has a sophisticated polyphonic poetics. ‘Of the Seven Masters’ shows that any single narrative and interpre­tation is necessarily biased by the particular situation of the narrator or interpreter, and that any decision based on such a single version and understanding of a narrative is rash. This is illustrated not only by the fifteen embedded stories and their interpretations but also within the frame narrative by three different accounts and interpretations of the central scene of sexual violence, neither of which justifies the quick decision and violent actions that follow. ‘Of the Seven Masters’ makes explicit that this one-sided narration even includes the heterodiegetic narrator, who in the prologue is presented as an interpreter of limited skill whose interpretations are biased by a specific didactic intent and who is on a par with the seven sages as only one of multiple voices.

description: In Jupiter's stratosphere, gaseous carbon monosulfide (CS) was first discovered in 1994 by millimeter and ultraviolet observations as a product induced by the collision of comet Shoemaker-Levy 9 (SL9). {To constrain sulfur chemistry, in 2013, 19 years after the SL9 event, we observed Jupiter's stratospheric CS $J$=7 -- 6 rotational transition at 0.8 mm wavelength by using the Atacama Submillimeter Telescope Experiment (ASTE) 10-m single dish telescope. The CS molecular line was successfully detected with 120 mK intensity in the antenna temperature scale. The obtained CS total mass shows $\sim$90$\%$ decrease relative to that observed in 1998. From the line shape analysis, CS is suggested to be present above the 0.2$^{+0.4}_{-0.15}$ mbar pressure level, which is comparable to that of determined in 1998 which was provided by SL9 along with CS, was observed up to the 2.0 mbar pressure region. The discrepancy of CS vertical distribution with \ce{H2O} and the decrease in its total mass may be attributed to the chemical loss of CS in Jupiter's stratosphere lower than the 0.2 mbar altitude region.
Nuclear spin diffusion in the central spin system of a GaAs/AlGaAs quantum dot

description: The spin diffusion concept provides a classical description of a purely quantum-mechanical evolution in inhomogeneously polarized many-body systems such as nuclear spin lattices. The central spin of a localized electron alters nuclear spin diffusion in a way that is still poorly understood. In contrast to previous predictions, we show experimentally that in GaAs/AlGaAs quantum dots the electron spin accelerates nuclear spin diffusion, without forming any Knight field gradient barrier. Such acceleration is present even at high magnetic fields, which we explain as a result of electron spin-flip fluctuations. Diffusion-limited nuclear spin lifetimes range between 1 and 10 s, providing plenty of room for recent proposals seeking to store and process quantum information using quantum dot nuclear spins.

description: The contribution offers, for the first time, a comprehensive survey of the pre-1500 Dutch tradition of ‘The Seven Sages’. The 13th-century Dutch-language version is the oldest extant translation in the continental West Germanic language area, with at least six different Dutch versions produced by the end of the 15th century. The article also argues that not only the Dutch texts should be considered a novel or prose romance (‘Prosaroman’) rather than a story collection. It demonstrates briefly that this genre allocation allows a more holistic interpretation of the versions and makes the importance of the two empresses visible, especially the critical representation of the second empress in the first Dutch version, and in all other versions the clear political strategy of the first empress for an ideal empire in the future. Finally, the article shows that the images, typography and layout of each print or manuscript provide a different focus even when the same wording is used, and suggests that each version needs to be considered as a multimodal entity.

The theory of the Double Solution: Dynamical issues in quantum systems in the semiclassical regime

description: The "dynamical mismatch" observed in quantum systems in the semiclassical regime challenge the Pilot wave model. Indeed the dynamics and properties of such systems depend on the trajectories of the classically equivalent system, whereas the de Broglie-Bohm trajectories are generically non-classical.\ In this work we examine the situation for the model favoured by de Broglie, the theory of the Double Solution (DS). We will see that the original DS model applied to semiclassical systems is also prone to the dynamical mismatch.\ However we will argue that the DS theory can be modified in order to yield propagation of the singularity in accord with the underlying classical dynamics of semiclassical systems.
Motif of Wisdom in the Byzantine ‘Book of Syntipas the Philosopher’

Year: 2023

description: The Book of Syntipas the Philosopher’ (‘BSP’) was translated from Syriac into Greek during the last decades of the 11th century. The prologue implicitly situates this work within didactic court literature. Much of the ‘BSP’ unfolds in a manner common to all Eastern versions, with two distinctive sections – the Ten Ethical Chapters and the Twenty Questions and Answers on Kingship, Morality, and Fate–being more elaborate than in any other surviving tradition. Their topics additionally emphasise the didactic character of this work by elabo­rating on the importance of philosophical instruction and ethical life. This paper focuses on the motif of wisdom and examines its impact on the architecture, narrative motivation, and character formation of the ‘BSP’. It also considers possible resonances of this topos for Byzantine reading audiences. Keywords Syntipas; Greek; Byzantine; Frame; Subplots
