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.

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.

This book was released on 2001-11-30 with total page 1032 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 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.
