Is MOND an Emergent Effective Law of a Complex Dark Matter Sector?
V. K. Oikonomou, Eleni I. Manouri
In this work we aim to present a new perspective for MOND theory, namely that MOND theory is not an answer for the missing matter at galactic scales, but it provides a phenomenolog…
From Quantum Correlations to Inflationary Tracking Scalar Field Evolution
V. K. Oikonomou
The tracking condition for single scalar field theory leads to analytic inflationary solutions, which are compatible with the current cosmic microwave background…
Analytic Singular Slow-roll Inflation
V. K. Oikonomou
We study a class of minimally coupled scalar field theories which leads to analytic solutions for the Hubble rate and the scalar field, where the scalar field obeys a generalized t…
Autonomous Dynamical System Approach for Inflationary Gauss-Bonnet Modified Gravity
V. K. Oikonomou
In this paper we shall analyze the gravity phase space, in the case that the corresponding dynamical system is autonomous. In order to make the dynamical system au…
On the Expanding Phase of a Singular Bounce and Intermediate Inflation: The Modified Gravity Description
V. K. Oikonomou
We demonstrate that the intermediate inflation scenario, is a singular inflation cosmology, with the singularity at the origin being a pressure and energy density singularity…
Gravitational Baryogenesis in Running Vacuum models
V. K. Oikonomou, Supriya Pan, Rafael C. Nunes
We study the gravitational baryogenesis mechanism for generating baryon asymmetry in the context of running vacuum models. Regardless if these models can produce a viable cosmologi…
Constraints on Singular Evolution from Gravitational Baryogenesis
V. K. Oikonomou
We investigate how the gravitational baryogenesis mechanism can potentially constrain the form of a Type IV singularity. Specifically, we study two different models with interestin…
Singular Bouncing Cosmology from Gauss-Bonnet Modified Gravity
V. K. Oikonomou
We study how a cosmological bounce with a Type IV singularity at the bouncing point, can be generated by a classical vacuum gravity. We focus our investigation on the behavi…
