F(R)-gravity and inflation
TL;DR: In this paper, a short review of inflation in F(R)-gravity is presented, where the early-time acceleration is analyzed in a higher derivative quantum gravitational model, which mainly reduces to F(r)-gravity.
Journal ArticleDOI
Single-field inflation, anomalous enhancement of superhorizon fluctuations and non-Gaussianity in primordial black hole formation
TL;DR: In this paper, the authors show that the Coleman-Weinberg model can induce double inflation and formation of primordial black holes (PBHs), because fluctuations that leave the horizon near the end of first inflation are anomalously enhanced at the onset of second inflation.

Quasinormal modes of D-dimensional de Sitter spacetime
TL;DR: In this article, exact solutions to the Dirac equation in D-dimensional de Sitter spacetime were obtained for the massive Dirac field in odd and even dimensions, respectively.

TL;DR: Bicep3 as discussed by the authors is a 550 mm-aperture refracting telescope for polarimetry of radiation in the cosmic microwave background at 95 GHz, with a focal plane area 5x larger than a Bicep2/Keck Array receiver.
Journal ArticleDOI
Scalar Induced Gravitational Waves Review
TL;DR: A review on the state-of-the-art of induced gravitational waves induced by primordial fluctuations is provided in this paper, where the intuitive physics behind induced gravitational wave and the general analytical formulation are revisited and unified.

Unity of All Elementary Particle Forces

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.
