Anisotropic non-perturbative zero modes for passively advected magnetic fields

Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: A first analytic assessment of the role of anisotropic corrections to the isotropic anomalous scaling exponents is given for the $d$-dimensional kinematic magneto-hydrodynamics problem in the presence of a mean magnetic field. The velocity advecting the magnetic field changes very rapidly in time and scales with a positive exponent $ξ$. Inertial-range anisotropic contributions to the scaling exponents, $ζ_j$, of second-order magnetic correlations are associated to zero modes and have been calculated non-perturbatively. For $d=3$, the limit $ξ\mapsto 0$ yields $\protect{ζ_j=j-2+ ξ(2j^3 +j^2 -5 j - 4)/[2(4 j^2 - 1)]} $ where $j$ ($j\geq 2$) is the order in the Legendre polynomial decomposition applied to correlation functions. Conjectures on the fact that anisotropic components cannot change the isotropic threshold to the dynamo effect are also made.
description: A sign in previous formula (28) has been changed. Previous perturbative expressions (29) and (30) (relative to (28)) are thus changed. Figure 1 has been modified.

description: We use quantum optimal control to identify fast collision-based two-qubit $\sqrt{\text{SWAP}}$ gates in ultracold atoms. We show that a significant speed up can be achieved by optimizing the full gate instead of separately optimizing the merge-wait-separate sequence of the trapping potentials. Our optimal strategy does not rely on the atoms populating the lowest eigenstates of the merged potential, and it crucially includes accumulation of quantum phases before the potentials are fully merged. Our analyses transcend the particular trapping geometry, but to compare with previous works, we present systematic results for an optical lattice and find greatly improved gate durations and fidelities.

description: The theoretical K factor, describing the difference between the leading and higher order cross sections, has no precise definition. The definition is sensitive to the order of the fit to the parton densities and the number of loops at which alpha_s is evaluated. We describe alternate ways to define the K factor and show how the definition affects its magnitude and shape for examples of hadroproduction of W^+ bosons, Drell-Yan lepton pairs, and heavy quarks. We discuss which definition is appropriate under certain circumstances.

The Outdoor Murals of Richard Haas: History, Challenges and Strategies for Preservation

Subjects: Arts
Cultural property--Protection

description: The outdoor murals of Richard Haas are complex, site-specific works of public art that actively engage the environment in which they are situated. Informed by the architectural history and development of a particular site and its surrounding environment and executed using the techniques of trompe l‘oeil painting, his murals stand as historical markers and references that seamlessly embed themselves into the urban landscape. Richard Haas first began painting large-scale murals on the exterior walls of buildings while living in New York City’s SoHo neighborhood in the mid-1970s as a response to the large-scale construction and urban renewal initiatives that were drastically changing the city landscape. His first mural, the SoHo Mural, is a trompe l’oeil extension of the cast-iron, front façade of 112 Prince Street and is located on the brick party wall of the six-story building. Since the creation of the mural on 112 Prince Street, Haas has gone on to produce a number of technically challenging and artistically significant murals that have become distinct features not only within the New York City landscape but within cities throughout the U.S and abroad.
Unfortunately, almost half of all Haas’ murals created over the past thirty-seven years have been destroyed and many of his remaining murals are at risk of destruction due to a host of threats and preservation challenges. Using the SoHo mural as a case study, this thesis examines the various challenges facing the preservation of outdoor murals and proposes potential strategies for the protection and preservation of not just Haas’ SoHo mural but for outdoor murals in general. In addition, this thesis examines the role the field of Historic Preservation plays in preserving outdoor murals and advocates for the field to consider the importance of outdoor murals within our local and collective histories.

description: The formation of regular patterns is a well-known phenomenon in condensed matter physics. Systems that exhibit pattern formation are typically driven and dissipative with pattern formation occurring in the weakly non-linear regime and sometimes even in more strongly non-linear regions of parameter space. In the early universe, parametric resonance can drive explosive particle production called preheating. The fields that are populated then decay quantum mechanically if their particles are unstable. Thus, during preheating, a driven-dissipative system exists. In this paper, we show that a self-coupled inflaton oscillating in its potential at the end of inflation can exhibit pattern formation.

Tidal disruption events as a site of an evolving relativistic spectral~line

description: In nuclei of galaxies strong tidal forces can destroy stars passing within a critical distance from the central super-massive black hole (SMBH). Observational signatures of tidal disruption events (TDEs) depend on the environment around the SBMH horizon and the level of its accretion activity. Evidence for optical and UV spectral features has been reported in TDE flares; nevertheless, to test the effects of General Relativity in the immediate vicinity of SMBH, the relativistically broadened and skewed X-ray line would tell us significantly more useful information. This will require to proceed beyond inactive nuclei. To this end we consider a system where the material from a disrupted star forms a gaseous ring that circularises near the tidal radius around SMBH, it gradually spreads in radius by viscous processes, and resides embedded within a hot corona. In our test calculation the remnant trail is assumed to be fully circularized and embedded in a hot environment and illuminated by X-rays from a surrounding corona or a jet base of (mild) AGN activity. We show the expected effects on the observed profile and the centroid energy. In future the evolving spectral features can enhance the diagnostic capability and provide a novel way to reveal the parameters of TDEs in such sources; namely, the distance of the remnant gas from the SMBH, the radial extent of the gaseous trail, and the spin of the SMBH could be measured.

description: We apply a recently proposed novel thermostating mechanism to an interacting many-particle system where the bulk particles are moving according to Hamiltonian dynamics. At the boundaries the system is thermalized by deterministic and time-reversible scattering. We show how this scattering mechanism can be related to stochastic boundary conditions. We subsequently simulate nonequilibrium steady states associated to thermal conduction and shear flow for a hard disk fluid. The bulk behavior of the model is studied by comparing the transport coefficients obtained from computer simulations to theoretical results. Furthermore, thermodynamic entropy production and exponential phase-space contraction rates in the stationary nonequilibrium states are calculated showing that in general these quantities do not agree.

description: We present a detailed analysis of Magellanic Bridge Cepheid sample constructed using the OGLE Collection of Variable Stars. Our updated Bridge sample contains 10 classical and 13 anomalous Cepheids. We calculate their individual distances using optical period--Wesenheit relations and construct three-dimensional maps. Classical Cepheids on-sky locations match very well neutral hydrogen and young stars distributions, thus they add to the overall Bridge young population. In three dimensions, eight out of ten classical Cepheids form a bridge-like connection between the Magellanic Clouds. The other two are located slightly farther and may constitute the Counter Bridge. We estimate ages of our Cepheids to be less than 300 Myr for five up to eight out of ten, depending on whether the rotation is included. This is in agreement with a scenario where these stars were formed in-situ after the last encounter of the Magellanic Clouds. Cepheids' proper motions reveal that they are moving away from both Large and Small Magellanic Cloud. Anomalous Cepheids are more spread than classical Cepheids in both two and three dimensions. Even though, they form a rather smooth connection between the Clouds. However, this connection does not seem to be bridge-like, as there are many outliers around both Magellanic Clouds.

description: We study the entanglement entropy and the mutual information in coupled harmonic systems at finite temperature. Interestingly, we find that the mutual information does not vanish at infinite temperature, but it rather reaches a specific finite value, which can be attributed to classical correlations solely. We further obtain high and low temperature expansions for both quantities. Then, we extend the analysis performed in the seminal paper by Srednicki (Phys. Rev. Lett. 71, 666 (1993)) for free real scalar field theories in Minkowski space-time in 3+1 dimensions at a thermal state. We find that the mutual information obeys an area law, similar to that obeyed by the entanglement entropy at vanishing temperature. The coefficient of this area law does not vanish at infinite temperature. Then, we calculate this coefficient perturbatively in an $1/μ$ expansion, where $μ$ is the mass of the scalar field. Finally, we study the high and low temperature behaviour of the area law term.

description: Welcome to DebyeCalculator! This is a simple tool for calculating the scattering intensity I(Q) through the Debye scattering equation, the Total Scattering Structure Function S(Q), the Reduced Total Scattering Function F(Q), and the Reduced Atomic Pair Distribution Function G(r) from an atomic structure. The Debye scattering equation can be used to compute the scattering pattern of any atomic structure and is commonly used to study both crystalline and non-crystalline materials with a range of scattering techniques like powder diffraction, total scattering with pair distribution function and small-angle scattering. Although the Debye scattering equation is extremely versatile, the computation of the double sum, which scales O(N2), has limited the practical use of the equation. Here, we provide an optimised code for the calculation of the Debye scattering equation on Graphics processing units (GPUs) which accelerate the calculations with orders of magnitudes.

description: A dynamical theory is studied in which a scalar field $ϕ$ in Einstein- Minkowski space is coupled to the four-velocity $N_μ$ of a preferred inertial observer in that space. As a consistent requirement on this coupling we study a principle of duality invariance of the dynamical mass- term of $ϕ$ at some universal length in the small-distance regime. In the large-distance regime duality breaking can be introduced by giving a back- ground value to $ϕ$ and a back-ground direction to $N_μ$. It is shown that, in an appropriate approximation, duality breaking can be related to the emergence of a characteristic phase in which the condensation of the ground state allows massive excitations with a characteristic scale of squared mass which agrees with present observational bound for the cosmological constant.

description: This dissertation seeks to offer the first extensive account of Raymond Aron's critical interactions with major US academics and intellectuals during the Cold War. In doing so it demonstrates that Aron regularly criticized the liberal ideology of his American Cold War allies using language remarkably similar to his much more famous critiques of French Marxism. It demonstrates this by looking at Aron's thinking on neoliberalism, theories of global development and international relations realism. It also offers an alternative interpretation of Aron's role in the so-called French liberal revival of the 1970s.

description: The methods for controlling spin states of negatively charged nitrogen-vacancy (NV) centers using microwave (MW) or radiofrequency (RF) excitation fields for electron spin and nuclear spin transitions are effective in strong magnetic fields where a level anti-crossing (LAC) occurs. A LAC can also occur at zero field in the presence of transverse strain or electric fields in the diamond crystal, leading to mixing of the spin states. In this paper, we investigate zero-field LAC of NV centers using dual-frequency excitation spectroscopy. Under RF modulation of the spin states, we observe sideband transitions and Autler-Townes splitting in the optically detected magnetic resonance (ODMR) spectra. Numerical simulations show that the splitting originates from Landau-Zener transition between electron spin |$\pm$1> states, which potentially provides a new way of manipulating NV center spin states in zero or weak magnetic field.

description: In the tropics and semi-tropics, pond systems of the second generation consisting of anaerobic high-rate digesters can significantly contribute to improving the water quality of river basins. If these plants are used to treat wastewater like from pig fattening stables or from municipalities a good treatment efficiency can be obtained at a low construction and operation cost. Furthermore the anaerobic process provides enough energy in the form of methane gas, if converted to electricity, to run the plant selfsufficiently at low CO2 emissions. This is another outstanding advantage when compared to the majority of other treatment options. Remarkably no highly qualified personnel are required to operate the plant. If well designed taking landscape and ecological aspects into account, biotopes of high biodiversity and natural appearance can be created. A very satisfying appearance can be obtained, if concrete is used reluctantly in construction and structures are partly or even completely covered by earth.

description: We construct a semiclassical expression for the Husimi function of autonomous systems in one degree of freedom, by smoothing with a Gaussian function an expression that captures the essential features of the Wigner function in the semiclassical limit. Our approximation reveals the "center and chord" estructure that the Husimi function inherits from the Wigner function, down to very shallow "valleys", where lie the Husimi zeroes. This explanation for the distribution of zeroes along curves relies on the geometry of the classical torus, rather than the complex analytical properties of the WKB method in the Bargmann representation. We evaluate the zeroes for several examples.

description: Beam finite elements for non linear plastic analysis of beam-like structures are formulated according to Displacement Based (DB) or Force Based (FB) approaches. DB formulations rely on modelling the displacement field by means of displacement shape functions. Despite the greater simplicity of DB over FB approaches, the latter provide more accurate responses requiring a coarser mesh. To fill the existent gap between the two approaches the improvement of the DB formulation without the introduction of mesh refinement is needed. To this aim the authors recently provided a contribution to the improvement of the DB approach by proposing new enriched adaptive displacement shape functions leading to the Smart Displacement Based (SDB) beam element. In this paper the SDB element is extended to include the axial force-bending moment interaction, crucial for the analysis of r/c cross sections. The proposed extension requires the formulation of discontinuous axial displacement shape functions dependent on the diffusion of plastic deformations. The stiffness matrix of the extended smart element is provided explicitly and shown to be dependent on the displacement shape functions updating. The axial force-bending moment interaction is approached by means of a fibre discretisation of the r/c cross section. The extended element, addressed as Fibre Smart Displacement Based (FSDB) beam element, is shown to be accurate and furthermore accompanied by the proposal of an optional procedure to verify strong equilibrium of the axial force along the beam element, which is usually not accomplished by DB beam elements. Given a fixed mesh discretisation the performance of the FSDB beam element is compared with the DB approach to show the better accuracy of the proposed element.

Gravity waves--Measurement

Thermosphere

description: In the middle and upper atmosphere, dynamics of scales from tens of meters to thousands of kilometers primary arise due to the influence of gravity waves propagating from lower altitudes. In order to understand the structure and variability of these regions of our planet's atmosphere, we must understand the propagation, influences, and dissipation of gravity waves. However, gravity waves and their influences are difficult to measure. Their largest and most observable effects occur in the remote mesosphere and lower thermosphere and the relevant spatial scales extend across many orders of magnitude. The EBEX group discovered a novel method to observe polar mesospheric clouds, which are a sensitive tracer of gravity waves and their associated dynamics. This discovery motivated the Polar Mesospheric Cloud Turbulence (PMC Turbo) experiment. Polar mesospheric clouds form an extremely thin but bright layer at roughly 80 kilometer altitude in which we can observe brightness fluctuations created by gravity wave dynamics and the resulting instabilities. PMC Turbo included seven pressure vessels, each of which contained an optical camera, hard drives, and computers that controlled the image capture, flight control, and communication with ground stations. The cameras captured spatial scales from gravity waves with wavelengths of roughly 10-100 kilometers, instability dynamics at scales from about 1-10 kilometers, and the fine structure at the inner scale of turbulence down to 20 meters. PMC Turbo flew at 38 kilometer altitude and remained afloat for nearly six days. During this time, it travelled from Esrange Space Center in Sweden to the Northwest Passage in Canada. Complementary data from other instruments provides additional atmospheric context to the PMC Turbo measurements. During flight, the PMC Turbo cameras captured images of polar mesospheric clouds tracing Kelvin-Helmholtz instabilities with a high signal-to-noise ratio. Kelvin-Helmholtz instabilities play major roles in energy dissipation and structure of geophysical fluids, and they have a close relationship with gravity waves. The PMC Turbo images include complicated interactions and secondary instabilities leading to turbulence. These dynamics provide insight into the atmospheric conditions and rate of energy dissipation in the mesosphere and lower thermosphere.

The two entities which shape an understanding of the poem’s conception of noise are Chaos, the conglomerate of mobile, conflicting elements with which the poem begins, and the personified Fama, whose domus is seen to contain a chaotic cosmos of words rather than elements. Within the loose frame provided by Chaos and Fama, the varied categories of noise in the Metamorphoses’ world, from nature sounds to speech, are seen to share qualities of changeability, mobility, and conflict, qualities which align them with the overall themes of flux and metamorphosis in the poem. I discuss three categories of Ovidian sound: in the first chapter, cosmological and elemental sound; in the second chapter, nature noises with an emphasis on the vocality of reeds and the role of echoes; and in the third chapter I treat human and divine speech and narrative, and the role of rumor. By the end of the poem, Ovid leaves us with a chaos of words as well as of forms, which bears important implications for his treatment of contemporary Augustanism as well as his belief in his own poetic fame.

description: The El Farol bar model, proposed to study the dynamics of competition of agents in a variety of contexts (W. B. Arthur, Amer. Econ. Assoc. Pap. and Proc. 84, 406 (1994)) is studied. We characterize in detail the three regions of the phase diagram (efficient, inefficient and better than random) of the simplest version of the model (D. Challet and Y.-C. Zhang, Physica A, 246, 407 (1997)). The efficient region is shown to have a rich structure, which is investigated in some detail. Changes in the payoff function enhance further the tendency of the model towards a wasteful distribution of resources.

description: Muon ring images observed with Imaging Atmospheric Cherenkov Telescopes (IACTs) provide a powerful means to calibrate the optical throughput of IACTs and monitor their optical point spread function. We investigate whether muons ring images can be used as the primary optical throughput calibration method for the telescopes of the future Cherenkov Telescope Array (CTA) and find several additional systematic effects in comparison to previous works. To ensure that the method achieves the accuracy required by CTA, these systematic effects need to be taken into account and minor modifications to the hardware and analysis are necessary. We derive analytic estimates for the expected muon data rates to be used for optical throughput calibration, monitoring of the optical point spread function, with achievable statistical and systematic uncertainties, and explore the potential of muon ring images as a secondary method of camera pixel flat-fielding.

description: As a historically racialized utterance, nigger has been a contested and despised word since the late 17th Century. Now, in the 21st Century, nigga is still considered one of the most impactful words in the English lexicon. This dissertation provides one situated and contingent analysis of nigga as a moment of excess in the Higher Education classroom. I wed Judith Butler’s theorizing of ex-citable speech via her analyses of J.L. Austin’s influential conceptualizations of speech acts and Louis Althusser’s interpellation to Henry Louis Gates’ theory of Signifyin(g) in order to interrogate the multitudinous articulations and appropriations of nigga as a Signifyin(g) performative. Through my theorizing of nigger-nigga as a Signifyin(g) performative, I interrogate the continuity and discontinuity of use specific to the English Composition and Literature classroom, as well as within multiple Higher Education classrooms and discussions. I interrogate use through the methodology of what I classify as Foucauldian-lite Discourse Analysis, in order to examine nigger and nigga as ex-citable speech. My intention is to interrogate how these utterances inflect and influence constructions of multiply conflicting and complimentary histories, identities, subjectivities and power relationships of professors and students in visible and invisible ways. The Untitled Supplemental Image is a metaphor for my methodology. The image is of my mother’s hands, which a woven throughout the dissertation, symbolically represents my memory of the first time I heard the utterance nigger.
The Outward Turn: Personality, Blankness, and Allure in American Modernism
Creators: Diebel, Anne
Publisher: name: Columbia University

Subjects: American literature

description: The history of personality in American literature has surprisingly little to do with the differentiating individuality we now tend to associate with the term. Scholars of nineteenth- and twentieth-century American culture have defined personality either as the morally vacuous successor to the Protestant ideal of character or as the equivalent of mass-media celebrity. In both accounts, personality is deliberately constructed and displayed. However, hiding in American writings of the long modernist period (1880s-1940s) is a conception of personality as the innate capacity, possessed by few, to attract attention and elicit projection. Skeptical of the great American myth of self-making, such writers as Henry James, Theodore Dreiser, Gertrude Stein, Nathanael West, and Langston Hughes invented ways of representing individuals not by stable inner qualities but by their fascinating--and, often, gendered and racialized--blankness. For these writers, this sense of personality was not only an important theme and formal principle of their fiction and non-fiction writing; it was also a professional concern made especially salient by the rise of authorial celebrity. This dissertation both offers an alternative history of personality in American literature and culture and challenges the common critical assumption that modernist writers took the interior life to be their primary site of exploration and representation. Instead, it argues for a reassessment of American modernism as crucially concerned--in its literary texts and in its professional literary culture--with surface, blankness, and opacity, all barriers to seeing inside which nonetheless produce an impression of personal power.
Hadamard renormalization, conformal anomaly and cosmological event horizons

description: The Hadamard renormalization prescription is used to derive a two dimensional analog of the renormalized stress tensor for a minimally coupled scalar field in Schwarzschild-de Sitter space time. In the two dimensional analog the minimal coupling reduces to the conformal coupling and the stress tensor is found to be determined by the (nonlocal) contribution of the anomalous trace and some additional parameters in close relation to the work [1]. To properly relate the stress tensor to the state of outwards signals coming from the direction of the black hole at late times we propose a cut-off hypothesis which excludes the contribution of the anomalous trace close to the black hole horizon. The corresponding cut-off scale is found to be related to the equilibrium-temperature of the cosmological horizon in a leading order estimate. Finally, we establish a relation between the radiation-temperature of the black hole horizon at large distance from the hole and the the anomalous trace and determine the correction term to the Hawking temperature due to the presence of the cosmological horizon.

Black Hole Production in the Presence of a Maximal Momentum in Horizon Wave Function Formalism

description: We study the Horizon Wave Function (HWF) description of a generalized uncertainty principle (GUP) black hole in the presence of two natural cutoffs as a minimal length and a maximal momentum. This is motivated by a metric which allows the existence of sub-Planckian black holes, where the black hole mass $m$ is replaced by $M=m\Big(1+\frac{β^{2}}{2}\frac{M_{pl}^{2}}{m^{2}}-β\frac{M_{pl}}{m}\Big)$. Considering a wave-packet with a Gaussian profile, we evaluate the HWF and the probability that the source might be a (quantum) black hole. By decreasing the free parameter the general form of probability distribution, ${\mathcal{P}}_{BH}$, is preserved , but this resulted in reducing the probability for the particle to be a black hole accordingly. The probability for the particle to be a black hole grows when the mass is increasing slowly for larger positive $β$, and for a minimum mass value it reaches to $0$. In effect, for larger $β$ the magnitude of $M$ and $r_{H}$ increases, matching with our intuition that either the particle ought to be more localized or more massive to be a black hole. The scenario undergoes a change for some values of $β$ significantly, where there is a minimum in ${\mathcal{P}}_{BH}$ , so this expresses that every particle can have some probability of decaying to a black hole. In addition, for sufficiently large $β$ we find that every particle could be fundamentally a quantum black hole.

The Paradox of Post-Abortion Care: A Global Health Intervention at the Intersection of Medicine, Criminal Justice and Transnational Population Politics in Senegal

description: Sociologists have used boundary work theory to explore the strategies deployed by professionals to define and defend jurisdictional authority in the arenas of the public, the law and the workplace. My dissertation investigates how medical providers and public health professionals negotiate authority over abortion in Senegal.  Although induced abortion is prohibited in Senegal, medical providers are permitted to treat complications of spontaneous and induced abortion, known as post-abortion care (PAC).  Introduced to Senegal in the late 1990s, the national PAC program is primarily supported by American development aid. This study explores how medical providers manage complications of abortion and in particular, how they circumvent the involvement of criminal justice authorities when they encounter suspected cases of illegal abortion. I also study how boundary work is accomplished transnationally through the practice of PAC within the policy framework of American anti-abortion population assistance and the national prohibition on abortion. Findings are based on an institutional ethnography of Senegal's national PAC program conducted over a period of 19 months between 2009 and 2011.  Data collection methods included in-depth interviews with 89 individuals, observation of PAC services, and review of PAC records at three hospitals.  I also conducted an archival review of abortion and PAC in court records, the media, and public health literature.  Findings show that medical providers and public health professionals perform discursive, technical and written boundary work strategies to maintain authority over PAC. Although these strategies have successfully integrated PAC into maternal health care, they have reinforced the stigma of abortion for women and health professionals.  They have also reproduced gendered disparities in access to quality reproductive health care.  PAC has been implemented in nearly 50 countries worldwide with varying legal restrictions on abortion.  This study illustrates not only how medical professionals practice abortion care in such settings, but also how they navigate a precarious array of medical, legal and global health obligations.
