# Inflation without Selfreproduction

@article{Mukhanov2014InflationWS, title={Inflation without Selfreproduction}, author={Viatcheslav F. Mukhanov}, journal={Fortschritte der Physik}, year={2014}, volume={63} }

We find a rather unique extension of inflationary scenario which avoids selfreproduction and thus resolves the problems of multiverse, predictability and initial conditions. In this theory the amplitude of the cosmological perturbations is expressed entirely in terms of the total duration of inflation.

Viscous fluid model in inflationary universe avoiding self-reproduction

- Mathematics
- 2016

We consider the description for the inflationary universe produced by viscous fluid in a flat Friedmann-LemaitreRobertson-Walker geometry. We have obtained the conditions of the existence regime of…

Inflation without self-reproduction in F(R) gravity

- Physics
- 2014

We investigate inflation in frames of two classes of F(R) gravity and check its consistency with Planck data. It is shown that F(R) inflation without self-reproduction may be constructed in close…

Features and implications of the plateau inflationary potentials

- Economics
- 2016

After the last PLANCK CMB data the plateau inflationary potentials are favored. I give some examples of such inflationary models emphasizing particularly on the Starobinsky model and its supergravity…

Bouncing Cosmologies: Progress and Problems

- Physics

We review the status of bouncing cosmologies as alternatives to cosmological inflation for providing a description of the very early universe, and a source for the cosmological perturbations which…

Initial Conditions for Inflation - A Short Review

- Psychology
- 2016

I give a brief review of the status of research on the nature of initial conditions required to obtain a period of cosmological inflation. It is shown that there is good evidence that in the case of…

Reconstruction of k-essence inflation in Horndeski gravity

- Physics

Abstract.In this paper, we analyzed inflation from k-essence in the framework of Horndeski gravity. In particular, we considered the models of canonical scalar field and k-essence with quadratic…

On the initial conditions for inflation with plateau potentials: the R+R 2 (super)gravity case

- Physics
- 2015

We discuss the initial conditions problem for inflation driven by the vacuum energy of a plateau potential, and in particular the Starobinsky inflation. We show that the supergravity embedding of the…

Reconstruction of inflation models

- Physics
- 2015

In this paper, we reconstruct viable inflationary models by starting from spectral index and tensor-to-scalar ratio from Planck observations. We analyze three different kinds of models: scalar field…

Implications of Planck2015 for inflationary, ekpyrotic and anamorphic bouncing cosmologies

- Physics
- 2015

The results from Planck2015, when combined with earlier observations from WMAP, ACT, SPT and other experiments, were the first observations to disfavor the "classic" inflationary paradigm. To satisfy…

Creation of matter is possible in the cosmological context, without cost of energy. This creation is regulated by the laws of quantum mechanics and general relativity. These elements are used to…

Quantum Fluctuations and a Nonsingular Universe

- Physics

Over a finite time, quantum fluctuations of the curvature disrupt the nonsingular cosmological solution corresponding to a universe with a polarized vacuum. If this solution held as an intermediate…

Scale-free primordial cosmology

- Physics

The large-scale structure of the universe suggests that the physics underlying its early evolution is scale-free. This was the historic motivation for the Harrison-Zel’dovich-Peebles spectrum and for…

Cosmology for Grand Unified Theories with Radiatively Induced Symmetry Breaking

- Physics

The treatment of first-order phase transitions for standard grand unified theories is shown to break down for models with radiatively induced spontaneous symmetry breaking. It is argued that proper…

Is the Universe a Vacuum Fluctuation?

The author proposes a big bang model in which our Universe is a fluctuation of the vacuum, in the sense of quantum field theory. The model predicts a Universe which is homogeneous, isotropic and…

Effect of intermediate Minkowskian evolution on CMB bispectrum

We consider a non-inflationary early Universe scenario in which relevant scalar perturbations get frozen out at some point, but then are defrosted and follow a long nearly Minkowskian evolution…

Quantum cosmological perturbations: predictions and observations
