This book was released on 2010 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formation of structures in the universe is one of the major questions in cosmology. The growth of structure in the linear regime of low amplitude fuctuations is well understood analytically, but N-body simulations remain the main tool to probe the "non-linear" regime where fuctuations are large. We study this question approaching the problem from the more general perspective to the usual one in cosmology, that of statistical physics and out-of-equilibrium dynamics of systems with long-range interaction. It is natural to improve our understanding of this system, reducing the question to fundamental aspects. We define a class of infnite 1D self-gravitating systems relevant to cosmology, and we observe strong qualitative similarities with the evolution of the analogous 3D systems. We highlight that the spatial clustering which develops may have scale invariant (fractal) properties, and that they display "self-similar" properties in their temporal evolution. We show that the measured exponents characterizing the scale-invariant clustering can be very well accounted for using a generalized "stable-clustering" hypothesis. Further by means of an analysis in terms of halo selected using a friend-of-friend algorithm we show that, in the corresponding spatial range, structures are, statistically virialized. Thus the non-linear clustering in these 1D models corresponds to the development of a "virialized fractal hierarchy". We conclude with a separate study which formalizes a classification of pair-interactions based on the convergence properties of the forces acting on particles as a function of system size, rather than the convergence of the potential energy

Download or read book Eighth Marcel Grossmann Meeting The On Recent Developments In Theoretical And Experimental General Relativity Gravitation And Relativistic Field Theories Proceedings Of The Meeting In 2 Parts written by Tsvi Piran and published by World Scientific. This book was released on 1999-05-14 with total page 1776 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1975, the Marcel Grossmann Meetings have been organized to provide opportunities for discussing recent advances in gravitation, general relativity and relativistic field theories, emphasizing mathematical foundations, physical predictions and experimental tests. The objective of these meetings is to facilitate exchange among scientists that may deepen our understanding of space-time structures and to review the status of ongoing experiments aimed at testing Einstein's theory of gravitation from either the ground or space.The Eighth Marcel Grossmann Meeting took place on 22-27 June, 1997, at the Hebrew University of Jerusalem, Israel. The scientific program included 25 plenary talks and 40 parallel sessions during which 400 papers were presented. The papers that appear in this book cover all aspects of gravitation, from mathematical issues to recent observations and experiments.

Download or read book Secular Evolution of Self Gravitating Systems Over Cosmic Age written by Jean-Baptiste Fouvry and published by Springer. This book was released on 2017-10-09 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tackling galactic evolution in a truly novel way, this outstanding thesis statistically explores the long-term evolution of galaxies, using recent theoretical breakthroughs that explicitly account for their self-gravity. While treating processes statistically, the astrophysical differences on each scale are also captured. As the archetype of self-amplified diffusion, the implications of the thesis go far beyond astrophysics. Gravity is the driving force in galaxies, from their far outskirts to their innermost cores. These “extended kinetic theories” offer unique physical insights into the competing dynamical processes at play, complementing N-body approaches. The thesis successfully gauges the role of nature and nurture in establishing the galaxies’ observed properties, using kinetic equations to capture both sources of fluctuations. Further, it shows how secular diffusion shapes the phase space structure of cold stellar disks. The thesis subsequently determines the characteristic timescales and examines the signatures of secular evolution in this framework on two scales: from the kinetic evolution in galactic disks and their thickening via giant molecular clouds; all the way down to the stellar resonant relaxation of the central cluster and its black hole.

Download or read book Introduction to Nonextensive Statistical Mechanics written by Constantino Tsallis and published by Springer Nature. This book was released on 2023-01-30 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on nonextensive statistical mechanics, a current generalization of Boltzmann-Gibbs (BG) statistical mechanics. Conceived nearly 150 years ago by Maxwell, Boltzmann and Gibbs, the BG theory, one of the greatest monuments of contemporary physics, exhibits many impressive successes in physics, chemistry, mathematics, and computational sciences. Presently, several thousands of publications by scientists around the world have been dedicated to its nonextensive generalization. A variety of applications have emerged in complex systems and its mathematical grounding is by now well advanced. Since the first edition release thirteen years ago, there has been a vast amount of new results in the field, all of which have been incorporated in this comprehensive second edition. Heavily revised and updated with new sections and figures, the second edition remains the go-to text on the subject. A pedagogical introduction to the BG theory concepts and their generalizations – nonlinear dynamics, extensivity of the nonadditive entropy, global correlations, generalization of the standard CLT’s, complex networks, among others – is presented in this book, as well as a selection of paradigmatic applications in various sciences together with diversified experimental verifications of some of its predictions. Introduction to Nonextensive Statistical Mechanics is suitable for students and researchers with an interest in complex systems and statistical physics.

This book was released on 2008-01-11 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Properties of systems with long range interactions are still poorly understood despite being of importance in most areas of physics. The present volume introduces and reviews the effort of constructing a coherent thermodynamic treatment of such systems by combining tools from statistical mechanics with concepts and methods from dynamical systems. Analogies and differences between various systems are examined by considering a large range of applications, with emphasis on Bose--Einstein condensates. Written as a set of tutorial reviews, the book will be useful for both the experienced researcher as well as the nonexpert scientist or postgraduate student.

Book excerpt: The workshop was about the developments of the thermodynamical and dynamical behavior of many-body systems in which the interactions decay very slowly with the distance: they present very strange properties, not found in the other systems. The possibility of testing the theoretical ideas in laboratory systems was the most innovative issue.
