The Story of Cosmological Theory

Science, 1917
Blank misgivings of a creature Moving about in worlds not realized. For him, perhaps it was enough to taste the joy of living, to watch the rising and the setting of the sun, to gaze upon the mountain, the river and the restless sea, and never to ask himself the question "what is this world in which I live, and how did it come into being?" But this ...

Chaos in M-theory Cosmology [PDF]

open access: possibleFortschritte der Physik, 2001
Summary: We review some recent work by \textit{T. Damour} and the author [Phys. Rev. Lett. 85, 920-923 (2000; Zbl 0978.83053)] on the chaotic behaviour of the gravitational field in the vicinity of a spacelike singularity in \(M\)-theory and superstring models. We stress in particular the rôle of the massless \(p\)-forms in this context.

Quantum Cosmology in CGBD Theory

International Journal of Theoretical Physics, 2002
A quantum cosmological model of gravitation interacting with a charged Brans-Dicke type scalar field has been discussed in the Pauli frame. The Wheeler-DeWitt equation is solved in the semi classical approximation by applying the WKB approximation. The wave function of the universe is obtained by applying Vilenkin-like and Hartle-Hawking-like boundary ...

Quantum Field Theory and Cosmology

1982
Experimental evidence points with ever increasing confidence towards an evolutionary cosmology. The standard framework used to confront this circumstance is the “hot big bang” theory: an initial classical singularity, possibly smeared by unknown quantum effects, produces a thermal distribution of the quanta of the matter field at a temperature close to

Supersymmetry: Theory, Experiment, and Cosmology

2006
Abstract This book describes the basic concepts of supersymmetric theories. It is aimed at theorists, experimentalists and cosmologists interested in supersymmetry, and its content is correspondingly divided into three distinct tracks of study.
