Cosmology, Inflation and the Physics of Nothing [PDF]

open access: yes, 2003
These four lectures cover four topics in modern cosmology: the cosmological constant, the cosmic microwave background, inflation, and cosmology as a probe of physics at the Planck scale. The underlying theme is that cosmology gives us a unique window on the ``physics of nothing,'' or the quantum-mechanical properties of the vacuum.

Inflation in the standard cosmological model

open access: yesComptes Rendus. Physique, 2015
Abstract The inflationary paradigm is now part of the standard cosmological model as a description of its primordial phase. While its original motivation was to solve the standard problems of the hot big bang model, it was soon understood that it offers a natural theory for the origin of the large-scale structure of the universe.

Inflation and axion cosmology

open access: yesPhysics Letters B, 1988
Abstract It is argued that the standard constraint ƒ⪷10 12 GeV in the axion theory and related constraints in the theories of other weakly interacting scalar fields do not apply in many versions of the inflationary universe scenario.

Stationarity of inflation and predictions of quantum cosmology [PDF]

open access: yesPhysical Review D, 1995
We describe several different regimes which are possible in inflationary cosmology. The simplest one is inflation without self-reproduction of the universe. In this scenario the universe is not stationary. The second regime, which exists in a broad class of inflationary models, is eternal inflation with the self-reproduction of inflationary domains. In

Lectures on string theory and cosmology

open access: yes, 2004
In these lectures I review recent attempts to apply string theory to cosmology, including string cosmology and various models of brane cosmology. In addition, the review includes an introduction to inflation as well as a discussion of transplanckian ...

Inflation from Susy quantum cosmology

open access: yes, 2004
We propose a realization of inverted hybrid inflation scenario in the context of n=2 supersymmetric quantum cosmology. The spectrum of density fluctuations is calculated in the de Sitter regimen as a function of the gravitino and the Planck mass, and ...

Brane inflation: A field theory approach in background supergravity

open access: yes, 2012
We propose a model of inflation in the framework of brane cosmology driven by background supergravity. Starting from bulk supergravity we construct the inflaton potential on the brane and employ it to investigate for the consequences to inflationary ...

Inflation: From Theory to Observation and Back

open access: yes, 1997
Alan Guth introduced cosmologists to inflation at the 1980 Texas Symposium. Since, inflation has had almost as much impact on cosmology as the big-bang model itself. However, unlike the big-bang model, it has little observational support. Hopefully, that
