Banks-Zaks Cosmology, Inflation, and the Big Bang Singularity
Michal Artymowski, Ido Ben-Dayan, Utkarsh Kumar
We consider the thermodynamical behavior of Banks-Zaks theory close to the conformal point in a cosmological setting. Due to the anomalous dimension, the resulting pressure and ene…
Inflation in supergravity from field redefinitions
Michal Artymowski, Ido Ben-Dayan
Supergravity (SUGRA) theories are specified by a few functions, most notably the real Kähler function denoted by , where K is a real Kähler pot…
Implications of extreme flatness in a general f(R) theory
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
We discuss a modified gravity theory defined by . We consider both finite and infinite number of terms in the series while requiring that th…
Inflation and dark energy from gravity
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
Inflationary paradigm has several issues, such as the pre-inflationary horizon problem or the eternal inflation. To avoid that the standard Starobinsky inflation has been extended…
Saddle point inflation from higher order corrections to Higgs/Starobinsky inflation
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
We explore two saddle point inflationary scenarios in the context of higher order corrections related to different generalisations of general relativity. Firstly, we deal with Jord…
Classical bouncing Universes from vector fields
Michal Artymowski, Zygmunt Lalak
For the anisotropic Universe filled with massless vector field in the General Relativity frame we obtain bouncing solution for one of scale factors. We obtain the Universe with fin…
