Reconstructing the primordial power spectrum from the CMB
TL;DR: In this article, the sensitivity of CMB and other experiments to wiggles, irregularities, and features in the primordial power spectrum is investigated, and a function space generalization of the usual Fisher matrix formalism is applied to a CMB experiment resembling Planck with and without ancillary data.
Journal ArticleDOI
Linear inflation from quartic potential
TL;DR: In this article, it was shown that if the inflaton has a non-minimal coupling to gravity and the Planck scale is dynamically generated, the results of Coleman-Weinberg inflation are confined in between two attractor solutions: quadratic inflation and linear inflation.
Journal ArticleDOI
Non-Gaussianity and the induced gravitational wave background
TL;DR: In this paper, a detailed study of the imprint of primordial non-Gaussianity on these induced gravitational waves was performed, emphasizing the role of disconnected and connected components of the primoridal trispectrum.
Journal ArticleDOI
Statistical nature of infrared dynamics on de Sitter background
TL;DR: In this article, an effective EoM for long wavelength modes of a massless scalar field with a general potential V() on de Sitter background was derived, and the authors investigated whether or not the effective EOM can be described as a classical stochastic process.

Cosmic acceleration with a negative cosmological constant in higher dimensions
Keiichi Maeda,Nobuyoshi Ohta +1 more
TL;DR: In this article, the authors studied the stability of the de Sitter solution with a cosmological constant and the Gauss-Bonnet curvature squared term and analyzed the possibility of expanding spacetime with a constant internal space.

Unity of All Elementary Particle Forces
Howard Georgi,Sheldon L. Glashow +1 more
TL;DR: In this paper, strong, electromagnetic, and weak forces are conjectured to arise from a single fundamental interaction based on the gauge group SU(5), which is known as SU(4).
Journal ArticleDOI
Decay of the false vacuum at finite temperature
TL;DR: In this article, a general theory of the decay of the metastable phase (false vacuum) at a finite temperature is developed, which will make it possible to study kinetics of phase transitions in a wide class of theories without complicated computer calculations.
Journal ArticleDOI
Phase transitions in gauge theories and cosmology
TL;DR: In this article, it is shown that at a sufficiently large temperature a phase transition takes place after which almost all elementary particles in the hot super-dense matter become massless and weak interactions become long-range like electromagnetic interactions.
