Download or read book Fourth Paris Cosmology Colloquium, Phase Transitions In Cosmology Euroconference written by H J De Vega and published by World Scientific. This book was released on 1998-06-30 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the lectures delivered at the Fourth Paris Cosmology Colloquium held at the Observatoire de Paris from June 4 - 9, 1997. This Colloquium ‘Phase Transitions in Cosmology’ is the first event of a EUROCONFERENCE series (‘Accompanying Measures’), with the support of the training and Mobility Programme of the Commision of the European Communities.The purpose of the Paris Cosmology Colloquia is to cover selected topics of high current interest in the interplay between cosmology and fundamental physics and to allow easy and fruitful interaction and communication between researchers in these areas. The main aim is to put in contact fundamental theoretical physics (including string theory) with real physical problems that arise in the study of the universe. The Paris Cosmology Colloquia are informal meetings which bring together physicists, astrophysicists and astronomers. Topics covered in this Fourth Paris Cosmology Colloquium included: cosmic microwave background, phase transitions in cosmology and evolution out of the equilibrium quantum fields, the value of the Hubble constant, fundamental strings in primordial cosmology, as well as other subjects of high current interest such as scaling laws in the interstellar medium and in the large scale structure, gravitational lensing and dark matter.
Book Synopsis String Theory Research Progress by : Ferenc N. Balogh
Download or read book String Theory Research Progress written by Ferenc N. Balogh and published by Nova Publishers. This book was released on 2008 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects called strings, rather than the zero-dimensional point particles that form the basis for the standard model of particle physics. The phrase is often used as shorthand for Superstring theory, as well as related theories such as M-theory. By replacing the point-like particles with strings, an apparently consistent quantum theory of gravity emerges. Moreover, it may be possible to 'unify' the known natural forces (gravitational, electromagnetic, weak nuclear and strong nuclear) by describing them with the same set of equations. Studies of string theory have revealed that it predicts higher-dimensional objects called branes. String theory strongly suggests the existence of ten or eleven (in M-theory) space-time dimensions, as opposed to the usual four (three spatial and one temporal) used in relativity theory.

Book Synopsis Phase Transitions in the Early Universe: Theory and Observations by : Héctor J. De Vega
Download or read book Phase Transitions in the Early Universe: Theory and Observations written by Héctor J. De Vega and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fundamental, profound review of the key issues relating to the early universe and the physical processes that occurred in it. The interplay between cosmic microwave background radiation, large scale structure, and the dark matter problem are stressed, with a central focus on the crucial issue of the phase transitions in the early universe and their observable consequences: baryon symmetry, baryogenesis and cosmological fluctuations. There is an interplay between cosmology, statistical physics and particle physics in studying these problems, both at the theoretical and the experimental / observational levels. Special contributions are devoted to primordial and astrophysical black holes and to high energy cosmic rays and neutrino astrophysics. There is also a special section devoted to the International Space Station and its scientific utilization.

Book Synopsis The B−L Phase Transition by : Kai Schmitz
Download or read book The B−L Phase Transition written by Kai Schmitz and published by Springer. This book was released on 2016-08-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several of the very foundations of the cosmological standard model — the baryon asymmetry of the universe, dark matter, and the origin of the hot big bang itself — still call for an explanation from the perspective of fundamental physics. This work advocates one intriguing possibility for a consistent cosmology that fills in the theoretical gaps while being fully in accordance with the observational data. At very high energies, the universe might have been in a false vacuum state that preserved B-L, the difference between the baryon number B and the lepton number L as a local symmetry. In this state, the universe experienced a stage of hybrid inflation that only ended when the false vacuum became unstable and decayed, in the course of a waterfall transition, into a phase with spontaneously broken B-L symmetry. This B-L Phase Transition was accompanied by tachyonic preheating that transferred almost the entire energy of the false vacuum into a gas of B-L Higgs bosons, which in turn decayed into heavy Majorana neutrinos. Eventually, these neutrinos decayed into massless radiation, thereby producing the entropy of the hot big bang, generating the baryon asymmetry of the universe via the leptogenesis mechanism and setting the stage for the production of dark matter. Next to a variety of conceptual novelties and phenomenological predictions, the main achievement of the thesis is hence the fascinating notion that the leading role in the first act of our universe might have actually been played by neutrinos.

Book Synopsis Cosmology Transition by : David Michalets
Download or read book Cosmology Transition written by David Michalets and published by . This book was released on 2020-07-07 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cosmology is in Transition. This book follows the book Observing Our Universe, which marked the need for a transition in cosmology. The first book explained several crucial mistakes in cosmology, some dating back 100 years, including the one which resulted in dark energy. This second book explains how cosmology can transition after fixing the mistakes and their consequences, and then considering alternatives for a better cosmology. The first book mentioned possible changes. This book describes some of the available alternatives for this transition in cosmology.The book weaves several threads to propose a new path for a new cosmology.Among those threads are: a) a new solar model based on one proposed by Hannes Alfven, but this model uses condensed matter, not gaseous plasma, b) a model for a spiral galaxy based on one proposed by Hannes Alfven, c) the author's quasar model, d) the replacement of relativity with the appropriate mix of the forces of electric, magnetic, and gravity. Gravity alone fails in cosmology, beyond the solar system.Relativity enabled the concept of a black hole, which arose only for the moving observer but then cosmology claimed this space-time could be applied to the universe. Relativity fails in cosmology. The claimed M87 black hole was really a plasmoid. Hannes Alfven was awarded the 1970 Nobel Prize in Physics for his important work developing plasma physics. Cosmology made a mistake when not adopting this crucial advance in physics. Nearly all the universe is plasma, or matter with an electrical charge, but cosmology maintained its reliance on the weaker force of gravity. The result was the dark matter mistake.This book offers alternatives for this transition. This is not a definitive plan. There is more than one alternative and this author cannot claim with certainty a correct path, but practical alternatives are offered. Our solar system is understood but there are problems beyond our Local Group. This transition to recover from fundamental mistakes has several clear alternatives for this time of transition. Perhaps this transition will be difficult. After the double debacle of dark matter and dark energy, cosmology needs suggestions.

This book was released on 2018-10-26 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: We described a natural particle physics basis for late-time phase transitions in the universe. Such a transition can seed the formation of large-scale structure while leaving a minimal imprint upon the microwave background anisotropy. The key ingredient is an ultra-light pseudo-Nambu-Goldstone boson with an astronomically large (O(kpc-Mpc)) Compton wavelength. We analyze the cosmological signatures of and constraints upon a wide class of scenarios which do not involve domain walls. In addition to seeding structure, coherent ultra-light bosons may also provide unclustered dark matter in a spatially flat universe, omega sub phi approx. = 1.
