Extreme electron acceleration with fixed radiation energy
Michael R. R. Good, Chiranjeeb Singha, Vasilios Zarikas
We examine the extreme situation of radiation from an electron that is asymptotically accelerated to the speed of light, resulting in finite emission energy. The analytic solution…
Swiss-cheese cosmologies with variable and from the renormalization group
Fotios K. Anagnostopoulos, Alfio Bonanno, Ayan Mitra +1
A convincing explanation for the nature of the dark energy and dark matter is still missing. In recent works a RG-improved swiss-cheese cosmology with an evolving cosmological cons…
Constraining the swiss-cheese IR-fixed point cosmology with cosmic expansion
Ayan Mitra, Vasilios Zarikas, Alfio Bonanno +2
In a recent work, it has been proposed that the recent cosmic passage to a cosmic acceleration era is the result of the existence of small anti-gravity sources in each galaxy and c…
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…
Effective field equations and scale-dependent couplings in gravity
Alfio Bonanno, Georgios Kofinas, Vasilios Zarikas
A new set of field equations for a space-time dependent Newton's constant and cosmological constant in the presence of matter is presented. We prove that it represent…
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…
