Monopoles as big as a universe
TL;DR: In this article, it was shown that, contrary to the standard belief, primordial monopoles expand exponentially during inflation in the new inflationary universe scenario and that inflation of monopoles continues without end even when inflation ends in the surrounding space.
Journal ArticleDOI
Stochastic gravitational wave backgrounds.
TL;DR: A review of the current state of research on the stochastic background of the early universe can be found in this paper, where the authors summarize the sources of these gravitational waves and methods used to observe them.
Journal ArticleDOI
Inflaton decay in supergravity
TL;DR: In this paper, it is shown that if the inflaton has a nonzero vacuum expectation value, it generically couples to any matter fields that appear in the superpotential at the tree level, and to any gauge sectors through anomalies in supergravity.

LRS Bianchi type I models with anisotropic dark energy and constant deceleration parameter
Özgür Akarsu,Can Battal Kilinç +1 more
TL;DR: In this paper, the authors examined locally rotationally symmetric Bianchi type I cosmological models in the presence of dynamically anisotropic dark energy and perfect fluid, where the conservation of the energy-momentum tensor of the DE is assumed to consist of two separately additive conserved parts.

Dynamically induced Planck scale and inflation
Kristjan Kannike,Gert Hütsi,Liberato Pizza,Antonio Racioppi,Martti Raidal,Alberto Salvio,Alessandro Strumia +6 more
TL;DR: In this article, the authors considered agravity as a dimensionless quantum gravity theory finding a multifield inflation that converges towards an attractor trajectory and predicts n ≥ 0.13 for the tensor-to-scalar ratio, which can be reduced down to ≈ 0.04 in the presence of large couplings.

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.
