Emission of gravitational radiation from ultra-relativistic sources

description: Recent observations suggest that blobs of matter are ejected with ultra-relativistic speeds in various astrophysical phenomena such as supernova explosions, quasars, and microquasars. In this paper we analyze the gravitational radiation emitted when such an ultra-relativistic blob is ejected from a massive object. We express the gravitational wave by the metric perturbation in the transverse-traceless gauge, and calculate its amplitude and angular dependence. We find that in the ultra-relativistic limit the gravitational wave has a wide angular distribution, like $1+\cosθ$. The typical burst's frequency is Doppler shifted, with the blue-shift factor being strongly beamed in the forward direction. As a consequence, the energy flux carried by the gravitational radiation is beamed. In the second part of the paper we estimate the anticipated detection rate of such bursts by a gravitational-wave detector, for blobs ejected in supernova explosions. Dar and De Rujula recently proposed that ultra-relativistic blobs ejected from the central core in supernova explosions constitute the source of Gamma-ray bursts. Substituting the most likely values of the parameters as suggested by their model, we obtain an estimated detection rate of about 1 per year by the advanced LIGO-II detector.

description: In a recent paper, M. F. Sacchi [Phys. Rev. A 96, 042325 (2017)] addressed the general problem of approximating an unavailable quantum state by the convex mixing of different available states. For the case of qubit mixed states, we show that the analytical solutions in some cases are invalid. In this Comment, we present complete analytical solutions for the optimal convex approximation. Our solutions can be viewed as correcting and supplementing the results in the aforementioned paper.

Comparison and evaluation of pair distribution functions, using a similarity measure based on cross‐correlation functions
Creators: name: Habermehl, Stefan
name: Schlesinger, Carina
name: Prill, Dragica
Publisher: name: International Union of Crystallography
Year: 2021

description: An approach for the comparison of pair distribution functions (PDFs) has been developed using a similarity measure based on cross‐correlation functions. The PDF is very sensitive to changes in the local structure, i.e. small deviations in the structure can cause large signal shifts and significant discrepancies between the PDFs. Therefore, a comparison based on pointwise differences (e.g. R values and difference curves) may lead to the assumption that the investigated PDFs as well as the corresponding structural models are not in agreement at all, whereas a careful visual inspection of the investigated structural models and corresponding PDFs may reveal a relatively good match. To quantify the agreement of different PDFs for those cases an alternative approach is introduced: the similarity measure based on cross‐correlation functions. In this paper, the power of this application of the similarity measure to the analysis of PDFs is highlighted. The similarity measure is compared with the classical Rwp values as representative of the comparison based on pointwise differences as well as with the Pearson product‐moment correlation coefficient, using polymorph IV of barbituric acid as an example.

description: The temperature dependent surface relaxation of Ag(111) is calculated by density-functional theory. At a given temperature, the equilibrium geometry is determined by minimizing the Helmholtz free energy within the quasiharmonic approximation. To this end, phonon dispersions all over the Brillouin zone are determined from density-functional perturbation theory. We find that the top-layer relaxation of Ag(111) changes from an inward contraction (-0.8 %) to an outward expansion (+6.3%) as the temperature increases from T=0 K to 1150 K, in agreement with experimental findings. Also the calculated surface phonon dispersion curves at room temperature are in good agreement with helium scattering measurements. The mechanism driving this surface expansion is analyzed.

This technique promises to greatly reduce the overhead for performing the integrals that involves non-local parts of pseudopotentials, with keeping a high degree of accuracy. Our procedure gives rise to no Pulay forces, unlike other real-space methods using adaptive coordinates. Moreover, we demonstrate the potential power of the method by calculating several properties of atoms and molecules.

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Exploitation of time-frequency properties of SPDC photon pairs has recently found application in many endeavors. Complete characterization and control over the states in this degree of freedom is of paramount importance for the development of optical quantum technologies. This is achieved by accessing information both on the joint spectral amplitude and the joint spectral phase. Here we propose a novel scheme based on the MICE algorithm, which aims at reconstructing the joint spectral phase by adopting a multi-shear approach, making the technique suitable for noisy environments. We report on simulations for the phase reconstruction and propose an experiment using a Franson modified interferometer.

description: Rovnoxestus gen. nov.
(Figs 1–4)
 Type species. Rovnoxestus rasnitsyni sp. nov. here designated.
 Etymology. The genus name, a masculine noun, was formed by combining the name of the fossil amber, Rovno, with an abbreviation of the name of a possibly related modern genus, Xestocephalus; from Greek: ξεστός, smooth, polished.
 Diagnosis. The new genus differs from other fossil and modern cicadellid genera in having the following combination of traits: head slightly broader than pronotum with anterior margin slightly produced and rounded to face, ocelli on anterior margin well separated from eyes, lateral frontal sutures extended to ocelli; forewing fully developed, venation somewhat elevated and complete, appendix very narrow; hind wing well developed with submarginal vein narrowly separated from apical margin; front tibia with stout anteroventral seta near midlength; hind femur macrosetal formula 2+2+1, tarsomere I with elongate ventromesal seta at apex.
 Rovnoxestus resembles Xestocephalites Dietrich & Gonçalves, 2014 from Eocene Baltic amber in overall habitus and in having a stout anteroventral seta near the midlength of the front femur, but differs in having the head wider than the pronotum, the pronotum relatively long, the hind femur macrosetal formula 2+2+1, and hind tarsomere I with an elongate ventroapical seta.

description: We develop a method to calculate the persistent currents and their spatial distribution (and transport properties) on graphs made of quasi-1D diffusive wires. They are directly related to the field derivatives of the determinant of a matrix which describes the topology of the graph. In certain limits, they are obtained by simple counting of the nodes and their connectivity. We relate the average current of a disordered graph with interactions and the non-interacting current of the same graph with clean 1D wires. A similar relation exists for orbital magnetism in general.

description: In this letter, it is proposed that cryogenic quantum bits can operate based on the nonlinearity due to the quantum capacitance of two-dimensional Dirac materials, and in particular graphene. The anharmonicity of a typical superconducting quantum bit is calculated, and the sensitivity of quantum bit frequency and anharmonicity with respect to temperature are found. Reasonable estimates reveal that a careful fabrication process can reveal expected properties, putting the context of quantum computing hardware into new perspectives.

description: The behaviour of Jacobi fields along a time-like geodesic running into an isotropic singularity is studied. It is shown that the Jacobi fields are crushed to zero length at a rate which is the same in every direction orthogonal to the geodesic. We show by means of a counter-example that this crushing effect depends crucially on a technicality of the definition of isotropic singularities, and not just on the uniform degeneracy of the metric at the singularity.

description: Terrorism is an age-old phenomenon. Mankind has witnessed acts of terrorism in some form or the otherthroughout history. But the ferocity of the 9/11 events in USA has totally changed the worlds’ understandingof the word ‘terrorism’. The day to day increase in the terrorist acts all over the world, made terrorism a globalproblem threatening the very existence of human race. Obviously lots of time and energies are being spentto counter and control this monster. Modern research, unlike the earlier studies that have focussed more onthe political roots of terrorism, dwells on the psychological underpinnings of this menace. Present review is anattempt to briefly summarise the available information on terrorism and the related matters.
Künstlerisch-ästhetische Praxis als Lebensbewältigung: Eine explorative Forschungsarbeit über Menschen mit geistiger Behinderung
Creators: name: Richard, Celestyn
Publisher: name: Hochschule Luzern – Soziale Arbeit
Year: 2024

description: Die vorliegende Arbeit befasst sich mit Menschen mit geistiger Behinderung, welche in einer Kunstabteilung einer sozialpädagogischen Einrichtung arbeiten. Dort wird die künstlerisch-ästhetische Praxis angewandt. Diese kann als Methode zur Lebensbewältigung nach Lothar Böhnisch angeschaut werden, da sie den Selbstwert, die soziale Anerkennung und die Selbstwirksamkeit fördert.

In Form einer qualitativ-empirischen Forschungsarbeit werden vier Personen mit geistiger Behinderung zu ihren künstlerischen Tätigkeiten befragt. Ziel dabei ist es herauszufinden, wie die künstlerischästhetische Praxis für Menschen mit geistiger Behinderung in sozialpädagogischen Einrichtungen Entwicklungsschritte in ihrer Lebensbewältigung sichtbar machen kann. 

Die Forschungsergebnisse zeigen, dass sich die künstlerisch-ästhetische Praxis auf Entwicklungsschritte aller drei Komponenten des psychosozialen Gleichgewichtes unterschiedlich auswirkt: In Bezug auf den Selbstwert erkennen die Befragten ihr Talent im Gestalten und betiteln sich sogar als Künstler*innen. Die soziale Anerkennung wird durch Öffentlichkeitsarbeiten wie einer Kunstausstellung gefördert. Durch diese werden neue Kontakte geknüpft und die Maler*innen erfahren Wertschätzung von aussen, beispielsweise durch den Verkauf ihren Bildern. Die Selbstwirksamkeit wird durch den Erwerb von neuen Fähigkeiten positiv gestärkt. Durch die Bilder ist es den Maler*innen möglich, ihre Meinung auszudrücken und ihre Werke im Nachhinein zu reflektieren. 

In diesem Sinn ist die Bachelorarbeit als Untersuchung bestehender Umstände anzuschauen. Aus den gewonnenen Erkenntnissen lassen sich Handlungsaufforderungen und Empfehlungen für die Soziale Arbeit ableiten.

Noise Correlations in time- and angular-resolved photoemission spectroscopy

Publisher: name: arXiv
Year: 2018
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: In time-resolved photoemission experiments, more than one electron can be emitted from the solid by a single ultra-short pulse. We theoretically demonstrate how correlations between the momenta of outgoing electrons relate to time-dependent two-particle correlations in the solid. This can extend the scope of time- and angular-resolved photoemission spectroscopy to probe superconducting and charge density fluctuations in systems without long-range order, and to reveal their dynamics independent of the electronic gap and thus unrestricted by the energy-time uncertainty. The proposal is illustrated for superconductivity in a BCS model. An impulsive perturbation can quench the gap on ultrafast timescales, while non-equilibrium pairing correlations persist much longer, even when electron-electron scattering beyond mean-field theory is taken into account. There is thus a clear distinction between a dephasing of the Cooper pairs and the thermalization into the normal state. While a measurement of the gap would be blind to such pairing correlations, they can be revealed by the angular correlations in photoemission.

Cretobibio rasnitsyni

description: Cretobibio rasnitsyni sp. nov.
(Fig. 1)
 Material. Holotype, male. CCNH-139, housed at Centro de Ciências Naturais e Humanas, Universidade Federal do ABC, Santo André, São Paulo, Brazil.
 Etymology. The species epithet honors Prof A.P. Rasnitsyn, an eminent Russian paleontologist, for all his collaboration in the study of insect fossils worldwide.
 Diagnosis. Wing with extremely short distal section of M 3+4.
 Locality and horizon. Crato Formation. Brazil, Ceará, Nova Olinda (07°05′30ʺ S, 39°40′46ʺ W), Pedreira Três Irmãos; upper Aptian, Lower Cretaceous.
 Description. Male. Small, total length, 4.4; thorax length, 1.4; wing length, 3.9; wing maximal width, 1.1; abdomen length, 2.8. Head. Head height smaller than thorax height. Antenna short, flagellomeres not discernible. Thorax. Scutum short, arched. Legs. Tibial spurs not discernible. Tarsi short. Wing. C ending beyond tip of R 5, close to wing apex; Sc ending just beyond midwing. Pterostigma large, pale brown. R 1 and R 4+5 strong, R 1 ending in C level with M 1+2 furcation. Basal section of Rs oblique, long, 4x longer than r -m. Slightly curved R 4+5 forked clearly distal to tip of R 1, reaching margin before wing apex; R 5 3.7x longer than short R 4, R 5 ending in C level with M 2 tip, slightly curved. Stem M more sclerotized basally to insertion of r -m, weaker more distally. M 1+2 fork narrow, 1.4x longer than R fork and 5x longer than distal section of M 3+4. Basal section of M 3+4 gently arched, level with tip of R 1, near to M 1+2 furcation; m -cu very long, 3.5x longer than distal section of M 3+4. Not possible to recognize microtrichia on wing membrane. Terminalia. Hypopygium poorly preserved, compact, gonocoxite massive, gonostylus well-developed, short, slightly elongate, probably digitiform (only apex visible).
 4+5
 Remarks. The new species differs from the type species in extremely short distal section of M 3+4 which is subequal to m -cu in C. montsecensis. Wing of C. rasnitsyni sp. nov. male is larger than in type species, based on female (3.9 instead of 3.0–3.2) although usually females are larger.

description: This thesis revisits the voices of the sirens in Grecian mythology, who I argue have had their vocal power stripped away in dominant cultural representations. Homer’s sirens were monstrous half-bird creatures with powerful, beautiful voices, but have come to be represented as visually-alluring mermaids. In counter to the siren’s historical de-vocalisation, I develop a “vocalised siren” framework to investigate actress vocal performance in a selection of films and interviews about actresses. I reconfigure the trope of the Hollywood “screen siren” star actress to analyse powerful, disruptive vocal performances, overall contributing to nuanced analysis of vocality in feminist film studies.

description: In this study, internal categories in the category of the crossed modules are characterized and it has been shown that there is a natural equivalence between the category of the crossed modules over crossed modules, i.e. crossed squares, and the category of the internal categories within the category of crossed modules. Finally, we obtain examples of crossed squares using this equivalence.

Reduction formula for fermion loops and density correlations of the 1D Fermi gas

description: Fermion N-loops with an arbitrary number of density vertices N > d+1 in d spatial dimensions can be expressed as a linear combination of (d+1)-loops with coefficients that are rational functions of external momentum and energy variables. A theorem on symmetrized products then implies that divergencies of single loops for low energy and small momenta cancel each other when loops with permuted external variables are summed. We apply these results to the one-dimensional Fermi gas, where an explicit formula for arbitrary N-loops can be derived. The symmetrized N-loop, which describes the dynamical N-point density correlations of the 1D Fermi gas, does not diverge for low energies and small momenta. We derive the precise scaling behavior of the symmetrized N-loop in various important infrared limits.

description: The equilibrium shapes of InAs quantum dots (i.e., dislocation-free, strained islands with sizes >= 10,000 atoms) grown on a GaAs (001) substrate are studied using a hybrid approach which combines density functional theory (DFT) calculations of microscopic parameters, surface energies, and surface stresses with elasticity theory for the long-range strain fields and strain relaxations. In particular we report DFT calculations of the surface stresses and analyze the influence of the strain on the surface energies of the various facets of the quantum dot. The surface stresses have been neglected in previous studies. Furthermore, the influence of edge energies on the island shapes is briefly discussed. From the knowledge of the equilibrium shape of these islands, we address the question whether experimentally observed quantum dots correspond to thermal equilibrium structures or if they are a result of the growth kinetics.

description: As the energy footprint generated by software is increasing at an alarming rate, understanding how to develop energy-efficient applications has become a necessity. Previous work has introduced catalogs of coding practices, also known as energy patterns. These patterns are yet limited to Mobile or third-party libraries. In this study, we focus on the Web domain--a main source of energy consumption. First, we investigated whether and how Mobile energy patterns could be ported to this domain and found that 20 patterns could be ported. Then, we interviewed six expert web developers from different companies to challenge the ported patterns. Most developers expressed concerns for antipatterns, specifically with functional antipatterns, and were able to formulate guidelines to locate these patterns in the source code. Finally, to quantify the effect of Web energy patterns on energy consumption, we set up an automated pipeline to evaluate two ported patterns: 'Dynamic Retry Delay' (DRD) and 'Open Only When Necessary' (OOWN). With this, we found no evidence that the DRD pattern consumes less energy than its antipattern, while the opposite is true for OOWN. Data and Material: https://doi.org/10.5281/zenodo.8404487

description: We present the results of fitting elastic $pp$ differential cross section data at 23.5 $\leq \sqrt{s} \leq$ 62.5 GeV with a novel analytic parametrization for the scattering amplitude. Making use of a fitting method, the errors from the free parameters are propagated to the imaginary part of the eikonal in the momentum transfer space. A novel systematic study of the effects coming from data at large momentum transfer is also performed. We find statistical evidence for the existence of eikonal zeros in the interval of momentum transfer 5-9 $GeV^{2}$.
