Legendre scalarization in gravity and cosmology

Spiros Cotsakis, Jose P. Mimoso, John Miritzis

We propose a new formulation of gravity, dubbed scalarized gravity, in which the Legendre transform is included as a dynamical term. This leads to a theory with secon…

Sudden Shock Waves in modified gravity

Ignatios Antoniadis, Spiros Cotsakis, Dimitrios Trachilis

We construct a generic asymptotic solution for modified gravity near a sudden singularity. This solution contains a fluid source with no equation of state and is function-counting…

Dispersive Friedmann universes and synchronization

Spiros Cotsakis

We introduce consideration of dispersive aspects of standard perfect fluid Friedmann cosmology and study the new qualitative behaviours of cosmological solutions that emerge as the…

IR quantum gravity solves naturally cosmic acceleration and its coincidence problem

Fotios K. Anagnostopoulos, Georgios Kofinas, Vasilios Zarikas

The novel idea is that the undergoing accelerated expansion of the universe happens due to infrared quantum gravity modifications at intermediate astrophysical scales of galaxies o…

The radiation instability in modified gravity

Spiros Cotsakis, Dimitrios Trachilis

We study the problem of the instability of inhomogeneous radiation universes in quadratic lagrangian theories of gravity written as a system of evolution equations with constraints…

Singularities and Phenomenological aspects of Asymptotic Safe Gravity

Vasilios Zarikas, Georgios Kofinas

Asymptotic Safety (AS) Program for quantum gravity keeps the same fields and symmetries with General Relativity and studies the associated gravitational action as a fundamental par…
