Fundamental Particle Structure in the Cosmological Dark Matter
TL;DR: In the early universe, the structure of particle symmetry breaking gives rise to cosmological phase transitions, from which macroscopic cosmology defects or primordial nonlinear structures can be originated as mentioned in this paper.
Journal ArticleDOI
Effects of critical collapse on primordial black-hole mass spectra
TL;DR: In this article, the authors consider the critical collapse scaling for a variety of models which produce primordial black-hole mass spectra and find that it generally leads to a shift, broadening and an overall decrease of the mass contained in primordial Black-Holes.
Journal ArticleDOI
Scale-invariance and the strong coupling problem
TL;DR: In this article, it was shown that the curvature fluctuations are scale-invariant and weakly coupled for at least 10 e-folds only if the background is close to de Sitter space.
Journal ArticleDOI
Inflation with a non-minimally coupled scalar field
TL;DR: In this paper, the authors derived a formula for density perturbations δϱ/ ϱ in the theory L = [(16π G 0 ) −1 + 1 2 ϵφ 2 ] R + 1 ϵ; k φ ;k −V(φ).

Effects of R3 and R□R terms on R2 inflation
Andrew L. Berkin,Keiichi Maeda +1 more
TL;DR: In this paper, the effects of R3 and R□R terms on the R2 inflationary scenario were analyzed using both direct analysis and conformal techniques, and it was shown that both terms restrict the initial conditions which will lead to a satisfactory inflationary cosmology.

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.
