A Study of an Einstein Gauss-Bonnet Quintessential Inflationary Model
K. Kleidis, V. K. Oikonomou
In this paper we study a class of quintessential Einstein Gauss-Bonnet models, focusing on their early and late-time phenomenology. With regard to the early-time phenomenology, we…
Autonomous Dynamical System Description of de Sitter Evolution in Scalar Assisted Gravity
K. Kleidis, V. K. Oikonomou
In this letter we will study the cosmological dynamical system of an gravity in the presence of a canonical scalar field with an exponential potential, by constructing t…
The power spectrum indicator: A new, efficient method for the early detection of chaos
Christos Vozikis, Konstantinos Kleidis, Stavros Papaioannou
To determine the regular or chaotic nature of the orbits in dynamical systems can be quite an issue. In this article, following Vozikis et al. (2000), we propose a new tool, namely…
Effects of Finite-time Singularities on Gravitational Waves
K. Kleidis, V. K. Oikonomou
We analyze the impact of finite-time singularities on gravitational waves, in the context of gravity. We investigate which singularities are allowed to occur during the infl…
Extended Supersymmetric Quantum Mechanics Algebras in Scattering States of Fermions off Domain Walls
V. K. oikonomou, K. Kleidis
We study the underlying extended supersymmetric structure in a system composed of fermions scattered off an infinitely extended static domain wall in the -plane. As we shall de…
Central Charge Extended Supersymmetric Structures for Fundamental Fermions Around non-Abelian Vortices
K. Kleidis, V. K. Oikonomou
Fermionic zero modes around non-abelian vortices are shown that they constitute two , supersymmetric quantum mechanics algebras. These two algebras can be combined under…
Testing extra dimensions with boundaries using Newton's law modifications
V. K. Oikonomou, K. Kleidis
Extra dimensions with boundaries are often used in the literature, to provide phenomenological models that mimic the standard model. In this context, we explore possible modificati…
