(In)stability of D-dimensional black holes in Gauss-Bonnet theory
No full textWe make an extensive study of evolution of gravitational perturbations of D-dimensional black holes in Gauss-Bonnet theory. There is an instability at higher multipoles l and large Gauss-Bonnet coupling alpha for D = 5, 6, which is stabilized at higher D. Although a small negative gap of the effective potential for the scalar type of gravitational perturbations exists for higher D and whatever alpha, it does not lead to any instability
Édition établie et présentation de « Serge Bonnet, Défense du catholicisme populaire, 2e éd., Paris, Éditions du Cerf, 2016.
No full textDans son exhortation apostolique La joie de l’Évangile, le pape François affirme la valeur de la piété populaire qu’il qualifie d’« œuvre de l’Esprit-Saint ». C’est un retour en grâce. Durant les années 1960 et 1970, les dévotions populaires étaient considérées par une partie du clergé comme une forme de paganisme dont il fallait affranchir les catholiques. Les saints sont congédiés des nefs, la communion solennelle supprimée et les fêtes votives délaissées. Le dominicain Serge Bonnet, à la fois prédicateur de talent et chercheur au CNRS, fut alors un des seuls à prendre au sérieux et à défendre la qualité spirituelle de ces pratiques. Très proche de Raymond Aron et de Philippe Ariès, admiré par Maurice Clavel, il sera une figure médiatique de l’Église catholique durant les années 1970-1980. Avec un positionnement iconoclaste assumé, il attaquera violemment le néocléricalisme des avant-gardes de gauche durant les années 1970 et il affirmera l’autonomie des laïcs. Renvoyant dos à dos les traditionalistes et les progressistes, il défendra un christianisme incarné et la nécessaire liberté de conscience et de dévotion des catholiques. L’intérêt des écrits de Serge Bonnet ne se borne pas à ce seul horizon polémique. Inlassable compilateur d’archives et de mémoire, ses recherches sur le catholicisme populaire méritent d’entrer dans les classiques des sciences sociales. De la géniale histoire de l’ermitage de Saint Rouin, à ses études sur la prière, la fête ou sur la domination cléricale, Serge Bonnet emprunte des pistes originales et renouvelle les analyses. Cet ouvrage rassemble pour la première fois ses recherches sur le petit peuple catholique et ses textes polémiques pour le défendre. L’œuvre de Serge Bonnet y apparaît dans toute sa densité, sa cohérence et sa profondeur. Toujours écrits avec un style incisif et une grande profondeur d’analyse, ces textes nous plongent dans une des grandes querelles qui ont divisé les catholiques après le concile Vatican II
Static Gauss-Bonnet black holes at large D
No full textWe study the static black holes in the large D dimensions in the Gauss-Bonnet gravity with a cosmological constant, coupled to the Maxewell theory. After integrating the equation of motion with respect to the radial direction, we obtain the effective equations at large D to describe the nonlinear dynamical deformations of the black holes. From the perturbation analysis on the effective equations, we get the analytic expressions of the frequencies for the quasinormal modes of charge and scalar-type perturbations. We show that for a positive Gauss-Bonnet term, the black hole could become unstable only if the cosmological constant is positive, otherwise the black hole is always stable. However, for a negative Gauss-Bonnet term, we find that the black hole could always be unstable. The instability of the black hole depends not only on the cosmological constant and the charge, but also significantly on the Gauss-Bonnet term. Moreover, at the onset of instability there is a non-trivial static zero-mode perturbation, which suggests the existence of a new non-spherically symmetric solution branch. We construct the non-spherical symmetric static solutions of the large D effective equations explicitly.NSFC [11275010, 11335012, 11325522]SCI(E)ARTICLE
THE HUMMEL BONNET An investigation of its production, design and significance in military uniform
Get PDFThe role of experiment has long been established as an effective means through which to explore past aspects of material culture, architecture and site formation processes (Coles 1979, Mathieu 2001 etc.). Items of dress have not routinely been incorporated in experimental projects. This investigation explored the utility of archaeological methods for gaining insight into how aspects of the uniformed body was constructed in Victorian Britain, focusing specifically on the production, design and significance in military uniform of the hummel bonnet. The work included a detailed review of available sources of evidence especially Calotypes, detailed study of extant artefact evidence and an experimental reconstruction of a hummel bonnet, using recognised experimental archaeological theory.
In undertaking this task, the techniques and approaches used are typical of experimental archaeology and analysis and examination of historical costume and are put to the test in order to evaluate their utility for this kind of research. The research considered material and method of construction aiming to adopt as near an accurate reconstruction as possible.
Findings of the research offer insight into experimental techniques and how these could be developed to further understanding of historical artefacts and makes comment about the role and value of re-enactment as a presentation of ‘history’ and the risks this may pose
Holographic superconductors with various condensates in Einstein-Gauss-Bonnet gravity
No full textWe study holographic superconductors in Einstein-Gauss-Bonnet gravity. We consider two particular backgrounds: a d-dimensional Gauss-Bonnet-AdS black hole and a Gauss-Bonnet-AdS soliton. We discuss in detail the effects that the mass of the scalar field, the Gauss-Bonnet coupling and the dimensionality of the AdS space have on the condensation formation and conductivity. We also study the ratio omega(g)/T(c) for various masses of the scalar field and Gauss-Bonnet couplings.National Natural Science Foundation of Chin
Configurational entropy as a constraint for Gauss-Bonnet braneworld models
No full textCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Processo FAPESP: 2015/08476-0Configurational entropy has been revealed as a reliable method for constraining some parameters of a given model [Phys. Rev. D 92, 126005 (2015); Eur. Phys. J. C 76, 100 (2016)]. In this work, we calculate the configurational entropy in Gauss-Bonnet braneworld models. Our results restrict the range of acceptability of the Gauss-Bonnet scalar values. In this way, the information theoretical measure in Gauss-Bonnet scenarios opens a new window to probe situations where the additional parameters, responsible for the Gauss-Bonnet sector, are arbitrary
Hydrodynamics with conserved current via AdS/CFT correspondence in the Maxwell-Gauss-Bonnet gravity
No full textUsing the AdS/CFT correspondence, we study the hydrodynamics with conserved current from the dual Maxwell-Gauss-Bonnet gravity. After constructing the perturbative solution to the first order based on the boosted black brane solution in the bulk Maxwell-Gauss-Bonnet gravity, we extract the stress tensor and conserved current of the dual conformal fluid on its boundary, and also find the effect of the Gauss-Bonnet term on the dual conformal fluid. Our results show that the Gauss-Bonnet term can affect the parameters such as the shear viscosity eta, entropy density s, thermal conductivity kappa and electrical conductivity sigma. However, it does not affect the so-called Wiedemann-Franz law which relates kappa to sigma, while it affects the ratio eta/s. In addition, another interesting result is that eta/s can also be affected by the bulk Maxwell field in our case, which is consistent with some previous results predicted through the Kubo formula. Moreover, the anomalous magnetic and vortical effects by adding the Chern-Simons term are also considered in our case in the Maxwell-Gauss-Bonnet gravity.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000291259200009&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Astronomy & AstrophysicsPhysics, Particles & FieldsSCI(E)20ARTICLE12null8

ENTROPY QUANTIZATION OF D-DIMENSIONAL GAUSS–BONNET BLACK HOLES
No full text The entropy and area spectra for D-dimensional Gauss–Bonnet black holes are investigated from two different approaches, which are the quasinormal modes approach developed by Hod, Kunstatter and Maggiore, and the very recent method proposed by Ropotenko. The two methods give the same results, which show that the entropy spectrum of Gauss–Bonnet black holes is equidistantly quantized with spacing ΔS = 2πℏ, while the area spectrum is not equally spaced. </jats:p
