Mini-discs around spinning black holes

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Accretion onto black holes in wind-fed binaries and in collapsars forms small rotating discs with peculiar properties. Such ``mini-discs'' accrete on the free-fall time without help of viscosity and nevertheless can have a high radiative efficiency. The inviscid mini-disc model was previously constructed for a non-rotating black hole. We extend the model to the case of a spinning black hole, calculate the structure and radiative efficiency of the disc and find their dependence on the black hole spin. If the angular momenta of the disc and the black hole are anti-aligned, a hydrodynamic analog of Penrose process takes place.

Maltese language

description: In what is officially a bilingual nation-state, post-colonial Maltese public institutions operate without explicit language policy guidance, such as provided in other jurisdictions by ‘language schemes’. Whilst both official languages are used in formal institutions, English appears to be the more popular choice of language for organisational texts. As social practices are a better indicator of actual language ideologies (Spolsky, 2004), a transdisciplinary approach was adopted, looking into select textually-mediated practices that coordinate institutionally-based activities (Smith, 1990b; Campbell and Gregor, 2004) and textual analysis (Fairclough, 2003). Taking texts as social spaces where the ideational and interpersonal metafunctions of language are activated (Halliday and Matthiessen, 2014; Fairclough, 1995) and writing as a disembedding mechanism (Giddens, 1990), choice of language in organisational texts may be due to the need for objectifying knowledge for sharing within the relations of ruling (Smith, 1990a; Campbell and Gregor, 2004), abstract, intangible social connections predominantly involved in the social organisation of knowledge societies within a global inter-state system (Hopkins and Wallerstein, 1982). The analysis suggests that language choice in institutional texts may depend on knowledge exchange systems designed for frontstage and backstage performativity. Furthermore, these language patterns imply that the environment within which these language practices occur needs to be accounted for in terms of polycentric social space (Lefebvre, 1991; Soja, 1985; Blommaert, 2007). Such variation, as well as the apparent stability of such language differentiation, may be better understood when looking beyond the borders of the nation-state and taking the world analysis system (WSA) as one influential model to understand language choice.

Bounds on Black Hole Entropy in Unitary Theories of Gravity

Year: 2010
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider unitary and weakly coupled theories of gravity that extend Einstein gravity and reduce to it asymptotically at large distances. Our discussion is restricted to such theories that, similarly to Einstein gravity, contain black holes as semiclassical states in a range of scales. We show that, at a given scale, the entropy of these black holes has to be larger than the number of elementary light species in the theory. Our bound follows from the observation that the black hole entropy has to be larger than the product of its mass and horizon radius (in units of Planck's constant divided by the speed of light) and the fact that, for any semiclassical black hole, this product has to be larger than the number of light species. For theories that obey our assumptions, the bound resolves the "species problem": the tension between the geometric, species-independent nature of black hole entropy and the proportionality of ordinary thermodynamic entropy to the number of species. We then show that, when black holes in Einstein's theory are compared to those in the extended theories at a fixed value of mass, the entropy of the Einstein black holes will always be minimal. Similar considerations are also applied to the entropy density of black branes in anti-de Sitter space.

title:  Parametric Study of Residual Stresses in Wire and Arc Additive Manufactured Parts
Creators: name: Abusalma, Hisham Khaled Jamil
Publisher: name: Old Dominion University Libraries
Year: 2020

description: Wire and Arc Additive Manufacturing (WAAM) is a cost-effective additive manufacturing process due to its capability to fabricate large metal parts with high deposition rate and low equipment cost. Although this method is gaining popularity in manufacturing industry, more research is needed to understand process parameters’ effects on residual stress (RS) distribution and part distortion. As such, a 3D thermo-elastic-plastic transient model was established in ABAQUS and employed to investigate the effect of process parameters such as the torch speed, the deposition power and the interlayer dwell time on RS distribution and distortion in WAAM part. The numerical model utilized a comprehensive three-dimensional transient heat transfer model to calculate the temperature distribution and gradient in WAAM process for various process parameters. The heat source was reproduced by a user subroutine DFLUX in ABAQUS. The calculated temperature was exported into mechanical model to predict residual stress and distortion. Variation of microstructural morphology in WAAM components is also critical as it can influence RS in the part. Therefore, the USDFLD user subroutine was utilized to incorporate mechanical property change due to microstructure variation in the mechanical analysis. Both thermal and mechanical models were validated with the experimental data. A 30-layer high wall was built using a GMA-WAAM process with a collaboration with students at Clarkson University.

The WAAM setup utilized a gas metal arc welding process for deposition of hot 718 Inconel electrode on a A36 steel substrate. Temperature histories, which is necessary for validating the thermal model, were collected at five locations on the substrate. Lattice spacing for strain calculation was measured by neutron diffraction technique on ex-situ basis, at Oak Ridge National Laboratory. The numerical results showed process parameters can induce significant impact on RS and distortion in the WAAM part. As such, these parameters should be optimized to produce WAAM parts with low RS.
Modeling the storage and transport of liquefied natural gas

Publisher: name: University of British Columbia

description: Understanding the behaviour of liquified natural gas is critical to appropriately designing the next generation of storage tanks used in industries ranging from industrial to personal transport, large scale storage, and distribution infrastructure. Simulation tools are an important part of this design process and having the right tool to use in these situations is critical for this projects' industry partner Westport Fuel Systems®. This thesis looks at the issue of simulation tools from the view of computational fluid dynamics via two related sub-studies. The first study examines the simulation of sloshing and vibrating LNG undergoing heat transfer within a Westport Fuel Systems® medium-sized on-truck fuel tank undergoing motion that is representative of a truck operating in an urban environment. The second study develops a method to simulate multiple miscible components of LNG simultaneously within a volume of fluid framework in order to simulate layering and compositional exchanges that occur in real LNG mixtures within a 3D domain. Both studies are conducted using OpenFOAM®, an open-source CFD library. In the first sub-study, adequate performance is achieved during sloshing trials in the Westport Fuel Systems® tank and it is concluded that, the effect of vibrations must not be ignored for modeling the storage of LNG in on-truck tank applications and that compressibleInterFoam is an acceptable solver for further development under these operating conditions. In the second sub-study, promising results and validations are shown using Fick's law of diffusion for a ternary component system where each component is tracked individually. As a relatively simple and cost-effective approach to modeling multicomponent miscible mixtures, it shows promise for use in modeling behaviour of LNG.

We give a detailed account of the current limitations and propose methods to overcome them. Our results have direct relevance for addressing of planes, strings or single atoms in higher dimensional optical lattices for quantum information processing or quantum simulations with standard methods in current experiments. Furthermore, our findings pave the way for arbitrary single qubit control with single site resolution.

description: Single crystalline FeTe$_{0.61}$Se$_{0.39}$ with a sharp superconducting transition at $T_{\textrm{c}} \sim$ 14 K is synthesized via slow furnace cooling followed by low-temperature annealing. The effect of annealing on the chemical and superconducting inhomogeneities is carefully characterized. We also report resistivity, magnetization, and magneto-optical images of this crystal. Based on the Bean model, critical current density is estimated to exceed $1 \times 10^5$ A/cm$^2$ below 5 K under zero field. Weak fish-tail effect is identified at lower temperatures.

Diffusion-Limited Aggregation on Curved Surfaces

description: We develop a general theory of transport-limited aggregation phenomena occurring on curved surfaces, based on stochastic iterated conformal maps and conformal projections to the complex plane. To illustrate the theory, we use stereographic projections to simulate diffusion-limited-aggregation (DLA) on surfaces of constant Gaussian curvature, including the sphere ($K>0$) and pseudo-sphere ($K<0$), which approximate "bumps" and "saddles" in smooth surfaces, respectively. Although curvature affects the global morphology of the aggregates, the fractal dimension (in the curved metric) is remarkably insensitive to curvature, as long as the particle size is much smaller than the radius of curvature. We conjecture that all aggregates grown by conformally invariant transport on curved surfaces have the same fractal dimension as DLA in the plane. Our simulations suggest, however, that the multifractal dimensions increase from hyperbolic ($K<0$) to elliptic ($K>0$) geometry, which we attribute to curvature-dependent screening of tip branching.

Optimal Matrix Product States for the Heisenberg Spin Chain

description: We present some exact results for the optimal Matrix Product State (MPS) approximation to the ground state of the infinite isotropic Heisenberg spin-1/2 chain. Our approach is based on the systematic use of Schmidt decompositions to reduce the problem of approximating for the ground state of a spin chain to an analytical minimization. This allows to show that results of standard simulations, e.g. density matrix renormalization group and infinite time evolving block decimation, do correspond to the result obtained by this minimization strategy and, thus, both methods deliver optimal MPS with the same energy but, otherwise, different properties. We also find that translational and rotational symmetries cannot be maintained simultaneously by the MPS ansatz of minimum energy and present explicit constructions for each case. Furthermore, we analyze symmetry restoration and quantify it to uncover new scaling relations. The method we propose can be extended to any translational invariant Hamiltonian.

Regularization in quantum field theory from the causal point of view

description: The causal approach to perturbative quantum field theory is presented in detail, which goes back to a seminal work by Henri Epstein and Vladimir Jurko Glaser in 1973. Causal perturbation theory is a mathematically rigorous approach to renormalization theory, which makes it possible to put the theoretical setup of perturbative quantum field theory on a sound mathematical basis. Epstein and Glaser solved this problem for a special class of distributions, the time-ordered products, that fulfill a causality condition, which itself is a basic requirement in axiomatic quantum field theory. In their original work, Epstein and Glaser studied only theories involving scalar particles. In this review, the extension of the method to theories with higher spin, including gravity, is presented. Furthermore, specific examples are presented in order to highlight the technical differences between the causal method and other regularization methods, like, e.g. dimensional regularization.

Linear wavelength correlation matrices of photospheric and chromospheric spectral lines: 1. Observations vs. modeling
Creators: name: Beck, C.

Publisher: name: arXiv
Year: 2009
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We investigate the linear correlation coefficient between the intensities at different wavelengths in photospheric and chromospheric spectral lines. Waves that propagate vertically through the stratified solar atmosphere affect different wavelengths at different times. This leads to a characteristic pattern of (non-)coherence of the intensity at various wavelengths. We derived the correlation matrices for several photospheric and chromospheric spectral lines from observations. For comparison with the observations, we calculate correlation matrices for spectra from LTE modeling approaches, 1-D NLTE simulations, and a 3-D MHD simulation run. We apply the correlation method also to temperature maps at different optical depth layers. We find that all photospheric spectral lines show a similar pattern: a pronounced asymmetry of the correlation between line core and red or blue wing. The pattern cannot be reproduced with a simulation of the granulation pattern, but with waves that travel upwards. All chromospheric spectral lines show a more complex pattern. In the case of Ca II H, the 1-D NLTE simulations of monochromatic waves produce a correlation matrix that qualitatively matches to the observations. The photospheric signature is well reproduced in the matrix derived from the 3-D MHD simulation. The correlation matrices of observed photospheric and chromospheric spectral lines are highly structured with characteristic and different patterns in every spectral line. The comparison with matrices derived from simulations and simple modeling suggests that the main driver of the detected patterns are upwards propagating waves. Application of the correlation method to 3-D temperature cubes seems to be a promising tool for a detailed comparison of simulation results and observations in future studies.

description: The reasons for the anomalously high thermal stability of cubane C8H8 and the mechanisms of its decomposition are studied by numerically simulating the dynamics of this metastable cluster at T = 1050 - 2000 K using a tight-binding potential. The decomposition activation energy is found from the temperature dependence of the cubane lifetime obtained from the numerical experiment; this energy is fairly high, Ea = 1.8 - 2.0 eV. The decomposition products are, as a rule, either C6H6 and C2H2 molecules or the isomer C8H8 with a lower energy.

title: Aerodynamically Driven Surface-bound Liquid Flows: Characterization and Modeling of Wetting Patterns
Creators: name: Feldmann, Johannes
Publisher: name: UNSPECIFIED
Year: 2020

description: The interaction of rain with a moving vehicle leads to the partial deposition of water drops on its surface. This results in thin surface bound film or rivulet flows moving under the combined action of gravity and aerodynamic forces. In the transportation industry, an actively engineered guidance of these flows has been identified as an effective measure to influence for example the soiling process of cars or the accretion of ice on airplanes, when flying through clouds of supercooled liquid drops. However, methodologies presently applied in the design process are mainly restricted to empirical testing in environmental wind tunnels. A simulation of such aerodynamically driven wetting is desirable, but to date involves extremely high computational efforts and costs and is in general not feasible. A significant decrease in this computational cost can be achieved by identifying and physically describing recurring elements of aerodynamically driven thin liquid flows in the form of models. These models can then be employed in computational schemes, allowing a coarser grid resolution. The development of such models for a selection of exemplary surface bound liquid flows is the goal of the present experimental and analytical study. To this aim a wind tunnel experiment has been designed in which a freely developing wetting pattern on a surface under controlled input conditions can be examined using visualization techniques. The acquired information about the flow of films, rivulets and drops allows changes in the wetting patterns under variation of input parameters to be identified, most on a statistical basis. The derived dependencies can then be used as input for model formulation. The modeling that has been carried out concentrates on the dynamics of aerodynamically driven film flows and on instability mechanisms which can explain the breakup of films and the formation of dry patches on the surface. The dynamics of the resulting film is then analyzed, exhibiting its characteristic V-shaped contraction into a rivulet. Finally, a criterion for the onset of aerodynamically driven rivulet meandering is introduced. The models developed for these flows exhibit good agreement with the experimentally captured data indicating that the main influencing factors have been properly identified. This offers the possibility to improve the numerical code used in vehicle development. In an outlook, it is proposed that the categorization of wetting patterns can serve as a framework to allow more detailed investigation on constitutive elements of a wetting pattern. In particular, it is suggested that future research concentrates on the dynamics of rivulet flow, as this element is prevalent in wetting patterns and existing explanations of rivulet stability and propagation are sparse, especially when an outer airflow is involved.
On the stability of self-gravitating accreting flows

description: Analytic methods show stability of the stationary accretion of test fluids but they are inconclusive in the case of self-gravitating stationary flows. We investigate numerically stability of those stationary flows onto compact objects that are transonic and rich in gas. In all studied examples solutions appear stable. Numerical investigation suggests also that the analogy between sonic and event horizons holds for small perturbations of compact support but fails in the case of finite perturbations.

Hill's Equation with Random Forcing Parameters: The Limit of Delta Function Barriers

description: This paper considers random Hill's equations in the limit where the periodic forcing function becomes a Dirac delta function. For this class of equations, the forcing strength $q_k$, the oscillation frequency $\af_k$, and the period are allowed to vary from cycle to cycle. Such equations arise in astrophysical orbital problems in extended mass distributions, in the reheating problem for inflationary cosmologies, and in periodic Schr{ö}dinger equations. The growth rates for solutions to the periodic differential equation can be described by a matrix transformation, where the matrix elements vary from cycle to cycle. Working in the delta function limit, this paper addresses several coupled issues: We find the growth rates for the $2 \times 2$ matrices that describe the solutions. This analysis is carried out in the limiting regimes of both large $q_k \gg 1$ and small $q_k \ll 1$ forcing strength parameters. For the latter case, we present an alternate treatment of the dynamics in terms of a Fokker-Planck equation, which allows for a comparison of the two approaches. Finally, we elucidate the relationship between the fundamental parameters $(\af_k,q_k)$ appearing in the stochastic differential equation and the matrix elements that specify the corresponding discrete map. This work provides analytic -- and accurate -- expressions for the growth rates of these stochastic differential equations in both the $q_k \gg1 $ and the $q_k \ll 1$ limits.
