Spacetime symmetries and the CPT theorem
No full textThis dissertation explores several issues related to the CPT theorem.
Chapter 2 explores the meaning of spacetime symmetries in general and time reversal in particular. It is proposed that a third conception of time reversal, 'geometric time reversal', is more appropriate for certain theoretical purposes than the existing 'active' and 'passive' conceptions. It is argued that, in the case of classical electromagnetism, a particular nonstandard time reversal operation is at least as defensible as the standard view. This unorthodox time reversal operation is of interest because it is the classical counterpart of a view according to which the so-called 'CPT theorem' of quantum field theory is better called 'PT theorem'; on this view, a puzzle about how an operation as apparently non-spatio-temporal as charge conjugation can be linked to spacetime symmetries in as intimate a way as a CPT theorem would seem to suggest dissolves.
In chapter 3, we turn to the question of whether the CPT theorem is an essentially quantum-theoretic result. We state and prove a classical analogue of the CPT theorem for systems of tensor fields. This classical analogue, however, appears not to extend to systems of spinor fields. The intriguing answer to our question thus appears to be that the CPT theorem for spinors is essentially quantum-theoretic, but that the CPT theorem for tensor fields applies equally to the classical and quantum cases.
Chapter4 explores a puzzle that arises when one puts the CPT theorem alongside a standard way of understanding spacetime symmetries, according to which (latter) spacetime symmetries are to be understood in terms of background spacetime structure. The puzzle is that a 'PT theorem' amounts to a statement that the theory may not make essential use of a preferred direction of time, and this seems odd. We propose a solution to that puzzle for the case of tensor field theories.Ph.D.Includes bibliographical references (p. 102)
Australian Author Marion Halligan - Word Artist
No full textAustralian author Marion Halligan admits that her life has been 'centred in domesticity' and this is where she draws on much of the material for her fiction. This could also be a reason why her work has been critically overlooked. Halligan is adept at capturing details of life in the domestic realm and weaving poignant, thought-provoking stories about experiences all of us can recognise in our own lives. It does not take the discerning reader long to discover the deeper considerations in her writing. According to Halligan, 'the world is a cruel and dark and difficult place and it is words that light the small candle flames that keep the dark at bay'[1]. Words and writing are essential to Halligan's life. In an essay titled 'Why I Write', she says: 'I write in order to put the world into words. I've always done that in my head. I can't perceive anything without trying to find words for it'[2]. Halligan's writing is an evocative exploration of the human condition. For Halligan, 'it is artists showing you what they see that educates the heart, in novels, in paintings, in photographs'.[3] The following essay examines three of Halligan's novels which feature an artist protagonist who is struggling to come to terms with the experience of loss, grief and bereavement. Lovers' Knots (1992), The Golden Dress (1998) and The Fog Garden (2001) are rich evocations of lives which are 'a walk with love and death ... The same subjects as the Greeks, and Shakespeare. [The] characters aren't kings and queens, aren't noble and grand, but their passions are as real'[4]
Review Of Dublin\u27s Merchant-Quaker: Anthony Sharp And The Community Of Friends, 1643-1707 By R. L. Greaves
No full textGreaves, author of several well-documented books on 17th-century dissenters, argues that Anthony Sharp (1643-1707) represents the transformation of Irish Friends from a charismatic sect into a respectable Protestant denomination. Sharp, whose father gave him several hundred pounds to begin business, ended by owning a woolen manufactory with 500 workers, at least 29 houses, and several thousand acres of land. Converted c. 1663, he became a minister, clerk and treasurer of various meetings, a controversialist who defended Friends against religious and political opponents, and a strict enforcer of the discipline. The meeting used Sharp\u27s legal training and business skills in a wide variety of activities: arbitrating between members, defending those persecuted for tithes, planning buildings, documenting persecutions, and raising money for schools. He emerges as devoted to the welfare of the Quaker community, but with no sympathy for Irish Catholics. Like George Whitehead, the leader of English Quakers after Fox\u27s death, Sharp showed little intellectual originality in his writings or activities for the meeting. Greaves\u27s account provides valuable new information about this significant sect whose Irish members numbered less than 5,000. For collections specializing in history of religion and Ireland.

Entre o conto e a crónica: o estudo de narrativas de autores açorianos
No full textA crónica é um género muito cultivado na literatura dos Açores, ao ponto de se introduzir noutros géneros narrativos, em particular o conto, tornando imprecisos os limites entre facto e ficção. Neste artigo, analisamos as narrativas híbridas de quatro escritores açorianos – Manuel Greaves, Daniel de Sá, Manuel Ferreira e Dias de Melo – procurando mostrar de que forma a intromissão da crónica alarga os contornos do género contístico.he chronicle is a widely cultivated genre in Azorean literature, to the point of permeating other narrative genres, particularly the short story, thereby blurring the distinction between fact and fiction. this article analyzes the hybrid narratives of four Azorean writers – Manuel Greaves, Daniel de Sá, Manuel Ferreira and Dias de Melo – and shows how the chronicle influences the short story by expanding its boundaries.publishe
ALMA and Herschel observations of the prototype dusty and polluted white dwarf G29-38
No full textJF gratefully acknowledges the support of the STFC via an Ernest Rutherford Fellowship. AB acknowledges the support of the ANR-2010 BLAN-0505-01 (EXOZODI). MCW and OP are grateful for the support of the European Union through ERC grant number 279973.ALMA Cycle 0 and Herschel PACS observations are reported for the prototype, nearest, and brightest example of a dusty and polluted white dwarf, G29-38. These long-wavelength programmes attempted to detect an outlying, parent population of bodies at 1–100 au, from which originates the disrupted planetesimal debris that is observed within 0.01 au and which exhibits LIR/L* = 0.039. No associated emission sources were detected in any of the data down to LIR/L* ∼ 10−4, generally ruling out cold dust masses greater than 1024–1025 g for reasonable grain sizes and properties in orbital regions corresponding to evolved versions of both asteroid and Kuiper belt analogues. Overall, these null detections are consistent with models of long-term collisional evolution in planetesimal discs, and the source regions for the disrupted parent bodies at stars like G29-38 may only be salient in exceptional circumstances, such as a recent instability. A larger sample of polluted white dwarfs, targeted with the full ALMA array, has the potential to unambiguously identify the parent source(s) of their planetary debris.Peer reviewe
