Canonical Scalar Field Inflation with String and -Corrections
S. D. Odintsov, V. K. Oikonomou, F. P. Fronimos
Assuming that a scalar field controls the inflationary era, we examine the combined effects of string and gravity corrections on the inflationary dynamics of canonical scala…
Unification of a Bounce with a Viable Dark Energy Era in Gauss-Bonnet Gravity
S. D. Odintsov, V. K Oikonomou, F. P. Fronimos +1
In this work we shall demonstrate that it is possible to describe in a unified way a primordial bounce with the dark energy era, in the context of Gauss-Bonnet modified gravity. Pa…
From a Bounce to the Dark Energy Era with Gravity
S. D. Odintsov, V. K. Oikonomou, Tanmoy Paul
In this work we consider a cosmological scenario in which the Universe contracts initially having a bouncing-like behavior, and accordingly after it bounces off, it decelerates fol…
Rotating Neutron Stars in F(R) Gravity with Axions
Artyom V. Astashenok, Sergey D. Odintsov
We investigate equilibrium configurations of uniformly rotating neutron stars in gravity with axion scalar field for GM1 equation of state (EoS) for nuclear matter. The mass-…
Unifying Holographic Inflation with Holographic Dark Energy: a Covariant Approach
Shinichi Nojiri, S. D. Odintsov, V. K. Oikonomou +1
In the present paper, we use the holographic approach to describe the early-time acceleration and the late-time acceleration eras of our Universe in a unified manner. Such ``hologr…
Swampland Implications of GW170817-compatible Einstein-Gauss-Bonnet Gravity
S. D. Odintsov, V. K. Oikonomou
We revisit the Einstein-Gauss-Bonnet theory in view of the GW170817 event, which compels that the gravitational wave speed is equal to in natural units. We use an alterna…
