Canonical Quantization of the Gowdy Model
Creators: name: Marugan, Guillermo A. Mena

Year: 1997
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The family of Gowdy universes with the spatial topology of a three-torus is studied both classically and quantum mechanically. Starting with the Ashtekar formulation of Lorentzian general relativity, we introduce a gauge fixing procedure to remove almost all of the non-physical degrees of freedom. In this way, we arrive at a reduced model that is subject only to one homogeneous constraint. The phase space of this model is described by means of a canonical set of elementary variables. These are two real, homogeneous variables and the Fourier coefficients for four real fields that are periodic in the angular coordinate which does not correspond to a Killing field of the Gowdy spacetimes. We also obtain the explicit expressions for the line element and reduced Hamiltonian. We then proceed to quantize the system by representing the elementary variables as linear operators acting on a vector space of analytic functionals. The inner product on that space is selected by imposing Lorentzian reality conditions. We find the quantum states annihilated by the operator that represents the homogeneous constraint of the model and construct with them the Hilbert space of physical states. Finally, we derive the general form of the quantum observables of the model.

description: We use algebraic methods to compute the simple Hurwitz numbers for arbitrary source and target Riemann surfaces. For an elliptic curve target, we reproduce the results previously obtained by string theorists. Motivated by the Gromov-Witten potentials, we find a general generating function for the simple Hurwitz numbers in terms of the representation theory of the symmetric group S_n. We also find a generating function for Hodge integrals on the moduli space M_{g,2} of Riemann surfaces with two marked points, similar to that found by Faber and Pandharipande for the case of one marked point.

description: Philosophers traditionally engage with metaphysical questions at the frontiers of physics by treating theories as putatively fundamental and complete. While this interpretative strategy sits uneasily with the limited success of past theories, it breaks down with the failure of our best current theories, Quantum Field Theories (QFTs), to consistently describe the world on the smallest scales. My dissertation examines how physicists' reconceptualization of successful theories as effective theories affects the epistemological and semantic foundations of the interpretative practice in physics. Chapter 1 offers a detailed analysis of renormalization theory, the set of methods that underwrite physicists' construction of empirically successful QFTs. Chapter 2 demonstrates that effective theories are not merely the only candidates left for scientific realists in QFT but also worth interpreting in realist terms. Chapter 3 shows that effective theories stand as a challenge for traditional approaches to scientific representation and realism in physics. I suggest that indexing truth to physical scales is the most promising way to account for the success of effective theories in realist terms. Chapter 4 develops the referential component of this proposal by taking a detour through the problem of referential failure across theory-change. I argue that to reliably assess referential success before theory-change, we need to index reference-fixing to the limited physical contexts where a given theory is empirically reliable.

Lowering of the Kinetic Energy in Interacting Quantum Systems

description: Interactions never lower the ground state kinetic energy of a quantum system. However, at nonzero temperature, where the system occupies a thermal distribution of states, interactions can reduce the kinetic energy below the noninteracting value. This can be demonstrated from a first order weak coupling expansion. Simulations (both variational and restricted path integral Monte Carlo) of the electron gas model and dense hydrogen confirm this and show that in contrast to the ground state case, at nonzero temperature the population of low momentum states can be increased relative to the free Fermi distribution. This effect is not seen in simulations of liquid He-3.

description: Decisions are part of everyday life. Some decisions require more structured processes to produce a rational and auditable methodology to support a choice between alternatives. This is especially true for closure planning and design, where there can be many alternatives with competing objectives. A decision analysis process brings together specialists from many fields, such as social, environmental, technical, and costing. Their fields of interest often have competing requirements and different risk profiles. A decision analysis process can describe the issues and objectives in plain language and effectively capture the different stakeholder viewpoints. Klohn Crippen Berger utilizes a decision analysis process that works well with the updated process and tools described in the 2019 International Council on Mining & Metals (ICMM) Integrated Mine Closure Guide1. This process builds on the Kepner-Tregoe method (K-T), a decision-making process designed to build consensus among stakeholders, consider a wide range of alternatives, identify potential risks, and develop a plan with specific actions. The closure planning decision analysis process starts with establishing the knowledge base/problem definition (e.g., site characteristics, inventory, etc.). The closure vision, situational appraisal, principles, and objectives can be developed from that base of understanding. The objectives associated with post-closure land use are integrated in this step as well. The risks and opportunities for closure can be identified once the objectives are set and the site characteristics are known. This review leads into the development of the closure concepts and activities/alternatives, and the evaluation of these concepts against the success criteria developed based on the closure vision and end land use. Making decisions about closure with involved, informed people and the right level of analyses applied at the right time can be the difference between successful mine closure and unforeseen long-term costs and risks.

description: „Vater, es wird mir eng im weiten Land, da geh ich lieber unter die Lawinen“ sagt Walther, der Sohn Wilhelm Tells, als dieser ihm bei einem Gang in die Stadt von der Unterdrückung und Unfreiheit außerhalb der Berge erzählt. Der Satz führt uns direkt in die Problematik des Umgangs mit Naturgefahren: Es geht immer um ein Abwägen von Gütern und Werten im Vergleich zu den Gefahren. Bei Schiller wird das Gut „Freiheit“ gegen die Gefahr „Lawinen“ gewogen und – wie beim Idealisten Schiller nicht anders zu erwarten – neigt sich die Waagschale zu Gunsten der Freiheit. Ein solches Abwägen ist Bestandteil des täglichen Lebens: Wenn man es eilig hat und noch schnell die stark befahrene Straße überquert, nimmt man das höhere Risiko auf sich. Der Bauer in Bangladesh ist sich der Überschwemmungsgefährdung wohl bewusst, baut aber – mangels Alternativen – dennoch dort an, weil er sich zumindest für dieses Jahr eine Ernte erhofft.
Die Abwägung von Risiken hängt zusammen mit der persönlichen Kenntnis der Gefahr und der Einschätzung der eigenen Fähigkeiten, mit ihr umzugehen. Mit dem Verkehr sind wir vertraut und glauben, uns und unsere Fähigkeiten zu kennen. Eine der wesentlichen Ursachen für die weit verbreitete Ablehnung der Kernenergie ist das Gefühl, etwas gänzlich Unbekanntem und Unbeeinflussbarem ausgeliefert zu sein. Die geringere Bedeutung, die heute den Naturgefahren beigemessen wird, hat sicher auch eine ihrer Ursachen in der zunehmenden Entfremdung von der Natur. Die Menschen ignorieren die Standortrisiken bewusst, wenn die sonstigen sozialen und wirtschaftlichen Bedingungen stimmen, wie am Beispiel der Bevölkerungsdichte im hoch erdbebengefährdeten Bereich von San Francisco, Silicon Valley bis nach Los Angeles deutlich wird.

description: Time-series spectrophotometric studies of exoplanets during transit using ground-based facilities are a promising approach to characterize their atmospheric compositions. We aim to investigate the transit spectrum of the hot Jupiter HAT-P-1b. We compare our results to those obtained at similar wavelengths by previous space-based observations. We observed two transits of HAT-P-1b with the Gemini Multi-Object Spectrograph (GMOS) instrument on the Gemini North telescope using two instrument modes covering the 320 - 800 nm and 520 - 950 nm wavelength ranges. We used time-series spectrophotometry to construct transit light curves in individual wavelength bins and measure the transit depths in each bin. We accounted for systematic effects. We addressed potential photometric variability due to magnetic spots in the planet's host star with long-term photometric monitoring. We find that the resulting transit spectrum is consistent with previous Hubble Space Telescope (HST) observations. We compare our observations to transit spectroscopy models that marginally favor a clear atmosphere. However, the observations are also consistent with a flat spectrum, indicating high-altitude clouds. We do not detect the Na resonance absorption line (589 nm), and our observations do not have sufficient precision to study the resonance line of K at 770 nm. We show that even a single Gemini/GMOS transit can provide constraining power on the properties of the atmosphere of HAT-P-1b to a level comparable to that of HST transit studies in the optical when the observing conditions and target and reference star combination are suitable. Our 520 - 950 nm observations reach a precision comparable to that of HST transit spectra in a similar wavelength range of the same hot Jupiter, HAT-P-1b. However, our GMOS transit between 320 - 800 nm suffers from strong systematic effects and yields larger uncertainties.

description: We study the exact solution for a two-mode model describing coherent coupling between atomic and molecular Bose-Einstein condensates (BEC), in the context of the Bethe ansatz. By combining an asymptotic and numerical analysis, we identify the scaling behaviour of the model and determine the zero temperature expectation value for the coherence and average atomic occupation. The threshold coupling for production of the molecular BEC is identified as the point at which the energy gap is minimum. Our numerical results indicate a parity effect for the energy gap between ground and first excited state depending on whether the total atomic number is odd or even. The numerical calculations for the quantum dynamics reveals a smooth transition from the atomic to the molecular BEC.

description: The effects of pre-ignition chemistry on laminar flame speed in methane/n-heptane fuel blends are investigated numerically, leading to flame speed modelling accounting for these effects. The laminar flame speeds of fuel blends are important input parameters for turbulent combustion models needed to support design of dual-fuel engines. At the autoignitive conditions found in engines, pre-ignition reactions cause the speed of the reaction front to increase. Fuels that exhibit two-stage ignition behaviour, such as n-heptane, also exhibit a two-stage increase in the speed of the reaction front as the reactant residence time increases. There is a corresponding reduction in the flame thickness until the residence time approaches the ignition delay time, whereupon the deflagrative scaling of flame thickness breaks down. The analysis shows that the increase in flame speed is due to distinct contributions of heat release, reactant consumption, and enhanced reactivity ahead of the flame. Addition of methane to n-heptane–air mixtures retards and reduces the first-stage increase in flame speed, in part due to dilution of the more-reactive n-heptane fuel, and in part due to consumption of radical species by the methane chemistry. The effect of methane/n-heptane fuel blending on flame speed is described adequately by a linear mixing rule. The effect of pre-ignition chemistry can then be modelled as a linear function of the progress variable ahead of the flame – accounting for heat release, reactant consumption, and enhanced reactivity ahead of the flame. The flame speed model accurately describes the variation of flame speed across the full range of methane/n-heptane blends at engine-relevant conditions, up to the deflagration/ignition transition.

Dynamical solutions representing traveling waves as well as stationary fields like those of black holes are discussed. Their properties are investigated by studying the geodesic structure of the corresponding space-times, as representing the motion of point-like test particles. The interaction between gravitational, electro-magnetic and scalar fields is also considered.

description: Das Wort „Ballistik" leitet sich aus dem griechischen Wort βαλλειν für „werfen" her und kann damit am besten mit „Lehre von den geworfenen Körpern" übersetzt werden. Wir heutigen verbinden damit allerdings keineswegs mehr eine Lehre vom Wurf, sondern eine Lehre von der Geschoßbahn eines Projektils, und in der Tat ist dies genau ein Teil der heutigen Bedeutung. Allerdings unterscheidet der moderne Ballistiker die Bereiche 1.Innenballistik
– beinhaltet die Vorgänge im Inneren einer Waffe beim Abschuss eines Projektiles, also insbesondere die Gasdynamik im Inneren eines Geschützrohres.
2.Außenballistik
– beinhaltet die Vorgänge während des Fluges des Projektils, also insbesondere die Flugbahn.
3.Abgangsballistik
– beinhaltet die Vorgänge an der Mündung eines Geschützrohres beim Schuss.
4. Zielballistik
– beinhaltet die Wirkung eines Geschosses im Ziel.
Wir wollen keine Raketenballistik betrachten, sondern von nur passiv angetriebenen Geschossen sprechen. Weiterhin wollen wir uns auf die Außenballistik konzentrieren und nur wenig zur Innenballistik, nichts aber zur Abgangs- und Zielballistik sagen. Auch soll nicht der eingeschränkte moderne Blick auf die Ballistik im Vordergrund stehen, der nur Gewehre und Kanonen sieht, sondern wir wollen uns auch mit Wurftheorien auseinander setzen, die am Beginn der Geschichte der Ballistik stehen.
Representing Mount Wutai's Past: A Study of Chinese and Japanese miracle tales about the Five Terrace Mountain
Creators: Andrews, Susan Patricia
Publisher: name: Columbia University
Year: 2013
Subjects: Religion

description: This dissertation explores diverse imaginings of Mount Wutai's significance put forward between the seventh and fourteenth centuries. It is built around a close reading of five principal miracle tales, various versions of which appear in court memorials, clerical biographies, diaries, statuary sets, temple chronicles, local gazetteers, and inscriptions preserved in China and Japan. Comparing the different portrayals of the mountain in these five primary narratives together with many other miracle tales set at the mountain, this thesis attempts to explain how and for whom the representation of Mount Wutai's significance worked. The dissertation proposes that during the course of its emergence as the focus of regional, national, and international devotion, the site's former importance was repeatedly recast in ways that met the needs of changing audiences in Tang (618-907) and Song (960-1279) China and Heian (794-1185) and Kamakura (1185-1333) Japan.

description: We show that it is impossible to improve the high-energy behavior of the tree-level four-point amplitude of a massive spin-2 particle by including the exchange of any number of scalars and vectors in four spacetime dimensions. This constrains possible weakly coupled ultraviolet extensions of massive gravity, ruling out gravitational analogues of the Higgs mechanism based on particles with spins less than two. Any tree-level ultraviolet extension that is Lorentz invariant and unitary must involve additional massive particles with spins greater than or equal to two, as in Kaluza-Klein theories and string theory.

description: We observe that the main feature of the Randall-Sundrum model, used to solve the hierarchy problem, is already present in a class of Yang-Mills plus gravity theories inspired by noncommutative geometry. Strikingly the same expression for the Higgs potential is found in two models which have no apparent connection. Some speculations concerning the possible relationships are given.

description: In this work we perform an ab-initio study of CdTiO3 perovskite in its orthorhombic phase using FLAPW method. Our calculations help to decide between the different cristallographic structures proposed for this perovskite from X-Ray measurements. We compute the electric field gradient tensor (EFG) at Cd site and obtain excellent agreement with available experimental information from a perturbed angular correlation (PAC) experiment. We study EFG under an isotropic change of volume and show that in this case the widely used "point charge model approximation" to determine EFG works quite well.

description: In den 1790er Jahren zeichnete der Münchner Künstler Johann Georg von Dillis (1759-1841) mit schwarzer Kreide und brauner Tusche locker das Halbfigurenbild eines jungen Mannes am Tisch. Das 18 × 15 cm messende Blatt zeigt wahrscheinlich einen Herrn „Schurich" – so ließe sich die Aufschrift der Rückseite deuten. Auf der Vorderseite, unter dem Bild, hat von Dillis „Wahnsinniger" notiert. Dieser Titel lässt den Betrachter sofort danach suchen, was an dem Mann „wahnsinnig" ist – im Sinne von „krankhaften Einbildungen unterworfen", „geistig gestört". Die alte, schon lange widerlegte Überzeugung, dass sich – wie ich es neutraler nennen möchte – psychische Ausnahmezustände oder psychische Krisen stets im Äußeren eines Menschen niederschlagen, ist noch immer lebendig in uns, als Abwehr des Irrationalen. Verdächtig scheinen zunächst die Stellung der Augen und die Haare Schurichs. Ist hier ein „wahnsinniger" Blick dargestellt oder Unordnung als Folge „wahnsinnigen" Verhaltens? Die Wahrnehmung wird relativiert, wenn man andere Porträtzeichnungen von Dillis’ aus derselben Zeit daneben hält: Der „verquere" Blick findet sich auch beim Bildnis eines Bärtigen mit Pelzmütze (wohl ein Rabbiner), so dass man auf Ungenauigkeit des Zeichners in diesem Detail schließen muss; und „unordentlich“ ist auch die Frisur des „Medalheurs“, möglicherweise, weil Lässigkeit in der Haartracht zu jener Zeit nach der Revolution modisch war.
Auffällig bei Schurich erscheinen weiterhin die Intensität des Blicks, der eine Mischung aus Angst und Anspannung verrät, und die gespannte Haltung. Da die Augen nicht auf uns gerichtet sind, wird die Anspannung nicht – zumindest nicht allein – vom Akt des Porträtierens ausgelöst. Der Mann reagiert, doch von Dillis zeigt nicht, worauf er reagiert. Ist dieser Zug aber ein Merkmal des „Wahnsinns“ oder nur des „Wahnsinnigen“ Schurich? Ist er überhaupt spezifisch? Die anderen beiden Porträtierten sehen den Betrachter auch nicht an. Vielleicht wollte von Dillis das Bildnis Schurichs durch dessen stärkere Mimik nur lebendiger gestalten?
Im Folgenden soll die besondere Leistung dieser Zeichnung weiter herausgearbeitet werden, indem ich sie mit früheren und wenig späteren Darstellungen von „Wahnsinn“ vergleiche sowie ihr Umfeld betrachte.

Representing the Invisible: The American Perceptions of Colonial Korea, 1910-1945
Creators: Kim, Jimin
Publisher: name: Columbia University
Year: 2011
Subjects: History

description: This study argues that American views of Korea during the period of Japanese colonial rule (1910-1945) shaped U.S. policy toward Korea in the colonial period and after, setting the stage for direct U.S. involvement in Korea's post-liberation years after 1945. Korean nationalists perceived the U.S. as a special ally and a model country, and expected it to play a positive role in resolving Korea's colonial status. In fact, American views of Korea in the early twentieth century were mixed, and depended greatly on the respective observers' relationship to Korea--whether as missionary, as scholar, or as diplomat. At the same time, Japan played a crucial role in mediating American views, reflecting the Asia colonizer's interest in winning international approval for its imperialist project. When Korean-American diplomatic relations began in the late nineteenth century, Americans observers typically regarded Korea as an uncivilized but distinct Asian country. This perception of backwardness persisted into the early twentieth century, even as Korea lost its status as a nation-state with the Japanese annexation of 1910. Awareness of Japanese subjugation of Korea would expand significantly in the period 1919-1922, as journalists and missionaries conveyed news of the March First Movement to the American public and Korean nationalists countered Japanese government efforts to influence international opinion. Nationalist efforts to influence U.S. policymaking in the 1920s and 1930s were persistent but never fully successful, in part because of Korean factional rivalries, changing Japanese strategies of colonial control, and American diplomats' desire to protect U.S. colonial interests in the Philippines. Although Korean nationalists failed to accomplish their ultimate goal of participating directly in the U.S. government's wartime discussions on Korea in the early 1940s, they nevertheless succeeded in making the American public aware that Korea was a cultural and racial entity distinct from Japan. This awareness would lay a foundation for American direct intervention in Korean political, social, and military problems after 1945.

description: The phonon-mode decomposition of the electron-phonon coupling in the MgB2-like system Li_{1-x}BC is explored using first principles calculations. It is found that the high temperature superconductivity of such systems results from extremely strong coupling to only ~2% of the phonon modes. Novel characteristics of E_2g branches include (1) ``mode lambda'' values of 25 and greater compared to a mean of $\sim 0.4$ for other modes, (2) a precipitous Kohn anomaly, and (3) E_2g phonon linewidths within a factor of ~2 of the frequency itself, indicating impending breakdown of linear electron-phonon theory. This behavior in borne out by recent inelastic x-ray scattering studies of MgB2 by Shukla et al.

Instantaneous Bethe-Salpeter equation: utmost analytic approach

description: The Bethe-Salpeter formalism in the instantaneous approximation for the interaction kernel entering into the Bethe-Salpeter equation represents a reasonable framework for the description of bound states within relativistic quantum field theory. In contrast to its further simplifications (like, for instance, the so-called reduced Salpeter equation), it allows also the consideration of bound states composed of "light" constituents. Every eigenvalue equation with solutions in some linear space may be (approximately) solved by conversion into an equivalent matrix eigenvalue problem. We demonstrate that the matrices arising in these representations of the instantaneous Bethe-Salpeter equation may be found, at least for a wide class of interactions, in an entirely algebraic manner. The advantages of having the involved matrices explicitly, i.e., not "contaminated" by errors induced by numerical computations, at one's disposal are obvious: problems like, for instance, questions of the stability of eigenvalues may be analyzed more rigorously; furthermore, for small matrix sizes the eigenvalues may even be calculated analytically.

description: We derive a generalized equation for the evolution of tensor perturbations in a cosmological background, taking into account higher-curvature contributions and a tree-level coupling to the dilaton in the string frame. The equation is obtained by perturbing the gravi-dilaton string effective action, expanded up to first order in $α'$. The $α'$ corrections can modify the low-energy perturbation spectrum, but the modifications are shown to be small when the background curvature keeps constant in the string frame.
