    A continuum path integral approach to the simulation of a unitary gas

    No full text
    This thesis presents an investigation by simulation of a unpolarized fermionic unitary gas system composed of two interacting fermionic species. While these species do not interact amongst themselves, they interact with each other using a pairwise zero-range delta function potential that has been tuned to unitarity i.e.the scattering length as=a_{s}=-\infty. A path integral Monte Carlo simulation of such a system is performed using an exact novel zero-range, delta function pair propagator which has been tuned to the unitary limit so that essentially all interactions amongst the interacting particles are comprised of s-wave interactions. This tuning in some sense yields the simplest imaginable interacting fermionic system which out to display features that would apply universally to interacting fermionic particles with particular interest within this field of study being in understanding the unitary BCS-BEC crossover. Numerical and ergodic challenges to sampling a divergent approximate path integral are discussed and solutions are proposed, implemented and explored. This thesis represents a step closer to this understanding by investigating this system with this novel propagator in a fixed-node path integral Monte Carlo framework and comparing to earlier work.Submission published under a 24 month embargo labeled 'U of I only', the embargo will last until 2017-08-01The student, Adam Knapp, accepted the attached license on 2015-04-28 at 22:24.The student, Adam Knapp, submitted this Dissertation for approval on 2015-04-28 at 22:30.This Dissertation was approved for publication on 2015-04-29 at 16:12.DSpace SAF Submission Ingestion Package generated from Vireo submission #8172 on 2015-09-29 at 14:58:24Made available in DSpace on 2015-09-29T20:49:23Z (GMT).

    What the Law Cannot Do: Samuel DeWitt Proctor\u27s Theological Response to An American Crisis, 1945-1997

    No full text
    Samuel De Witt Proctor (1921-1997) accomplished many things in his life. He was an educator, administrator, ordained Baptist pastor, and author. He was educated at Virginia State University and Virginia Union University, the University of Pennsylvania, Crozer Theological Seminary, Yale University, and Boston University School of Theology. He served in different government capacities during the Kennedy and Johnson administrations, including stints as an associate director of the Peace Corps and Office of Economic Opportunity. His academic career included presidential posts at Virginia Union University and North Carolina A and T State University, teaching duties at Rutgers University, and lectures at various colleges and seminaries following his retirement. He also served churches in Providence, Rhode Island and Harlem, New York (successor to Adam Clayton Powell Jr. at the prominent Abyssinian Baptist Church). Proctor\u27s public ministry spanned six decades..

    Memory, space and time: Researching children's lives

    No full text
    This article discusses the research approach in 'Pathways through Childhood', a small qualitative study drawing on memories of childhood. The research explores how wider social arrangements and social change influence children's everyday lives.The article discusses the way that the concepts of social memory, space and time have been drawn on to access and analyse children's experiences, arguing that attention to the temporal and spatial complexity of childhood reveals less visible yet formative influences and connections. Children's everyday engagements involve connections between past and present time, between children, families, communities and nations, and between different places. Children carve out space and time for themselves from these complex relations. © The Author(s) 2010

    Silence and the crisis of self - legitimation in English romanticism

    No full text
    My thesis depicts the crisis of self-legitimation that has accompanied the onset of modern hermeneutics, with its historicised and organicised version of the Enlightenment's 'universal perspective.' In this it follows the lead of the contemporary hermeneuticist Hans- Georg Gadamer in resuscitating the notion of prejudice, but contrasts it with Hannah Arendt's discussion of the human condition. She implicitly locates the problem in modern hermeneutics, the aporia, in the very philosophy of life that Gadamer embraces as its solution. Gadamer confuses the task of the humanities as a search for truth with what it ought to be, a search for meaning. I begin with his depiction of Kant's attack on the sensus communis; I conclude with an examination of the consequences of this attack on the orientation and interpretative practices of current schools of literary criticism with specific reference to Keats's Ode on a Grecian Urn. In the central chapter, I focus upon Coleridge's attack on Wordsworth's Preface to Lyrical Ballads (1802) in the Bioeraphia Literaria, reading it as a fundamental defence of prejudice based on the very fact that man has been made in imago Dei. The consequent logocentricity of humanity that Coleridge insists upon opposes Wordsworth's emphasis upon a transcendental idea of 'feeling.' This fundamental notion forms the basis of Coleridge's definition of the primary imagination. I argue the distinctiveness of his definition from that of the other Romantics and maintain its necessity to escape the aporia. This point is proved negatively by Shelley's Mont Blanc, which seizes upon the radical consequences of Wordsworth's poetics, presenting both heresy and obscurity in the poem. The word 'crisis' thus reflects the urgency with which I advocate the need to re-adopt Coleridge's emphases in contemporary literary criticism

    Moving together: the organisation of non-verbal cues during multiparty conversation

    No full text
    PhDConversation is a collaborative activity. In face-to-face interactions interlocutors have mutual access to a shared space. This thesis aims to explore the shared space as a resource for coordinating conversation. As well demonstrated in studies of two-person conversations, interlocutors can coordinate their speech and non-verbal behaviour in ways that manage the unfolding conversation. However, when scaling up from two people to three people interacting, the coordination challenges that the interlocutors face increase. In particular speakers must manage multiple listeners. This thesis examines the use of interlocutors’ bodies in shared space to coordinate their multiparty dialogue. The approach exploits corpora of motion captured triadic interactions. The thesis first explores how interlocutors coordinate their speech and non-verbal behaviour. Inter-person relationships are examined and compared with artificially created triples who did not interact. Results demonstrate that interlocutors avoid speaking and gesturing over each other, but tend to nod together. Evidence is presented that the two recipients of an utterance have different patterns of head and hand movement, and that some of the regularities of movement are correlated with the task structure. The empirical section concludes by uncovering a class of coordination events, termed simultaneous engagement events, that are unique to multiparty dialogue. They are constructed using combinations of speaker head orientation and gesture orientation. The events coordinate multiple recipients of the dialogue and potentially arise as a result of the greater coordination challenges that interlocutors face. They are marked in requiring a mutually accessible shared space in order to be considered an effective interactional cue. The thesis provides quantitative evidence that interlocutors’ head and hand movements are organised by their dialogue state and the task responsibilities that the bear. It is argued that a shared interaction space becomes a more important interactional resource when conversations scale up to three people
