The Cosmic Triangle : Revealing the State of the Universe
TL;DR: The cosmic triangle as mentioned in this paper is a way of representing the past, present, and future status of the universe and its current location within the cosmic triangle is determined by the answers to three questions: How much matter is in the universe? Is the expansion rate slowing down or speeding up? And, is the universe flat?
Journal ArticleDOI
Inflation dynamics and reheating
TL;DR: The theory and phenomenology of reheating and preheating after inflation is reviewed in this paper, providing a unified discussion of both the gravitational and nongravitational features of multifield inflation.
Journal ArticleDOI
Gravity Waves and Linear Inflation from Axion Monodromy
TL;DR: In this article, a general mechanism for chaotic inflation driven by monodromy-extended closed-string axions is proposed, compatible with moduli stabilization and can be realized in many types of compactifications, including warped Calabi-Yau manifolds and more general Ricci-curved spaces.

TL;DR: In this paper, the role of torsion in gravity has been extensively investigated along the main direction of bringing gravity closer to its gauge formulation and incorporating spin in a geometric description.

Inflation-Produced, Large-Scale Magnetic Fields
TL;DR: This work has considered four models in which the conformal invariance of electromagnetism is broken and the primeval magnetic fields which result can have astrophysically interesting strengths, but are very model-dependent.

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).

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.
