Teleparallel gravity: from theory to cosmology

S Bahamonde, KF Dialektopoulos… - Reports on Progress …, 2023 - iopscience.iop.org
Teleparallel gravity (TG) has significantly increased in popularity in recent decades, bringing
attention to Einstein's other theory of gravity. In this Review, we give a comprehensive …

Finite-time cosmological singularities and the possible fate of the Universe

J de Haro, S Nojiri, SD Odintsov, VK Oikonomou, S Pan - Physics Reports, 2023 - Elsevier
Singularities in any physical theory are either remarkable indicators of the unknown
underlying fundamental theory, or indicate a change in the description of the physical reality …

[HTML][HTML] Inflationary cosmology in modified gravity theories

K Bamba, SD Odintsov - Symmetry, 2015 - mdpi.com
We review inflationary cosmology in modified gravity such as R 2 gravity with its extensions
in order to generalize the Starobinsky inflation model. In particular, we explore inflation …

Cosmological bouncing solutions in f(TB) gravity

M Caruana, G Farrugia, J Levi Said - The European Physical Journal C, 2020 - Springer
Teleparallel Gravity offers the possibility of reformulating gravity in terms of torsion by
exchanging the Levi-Civita connection with the Weitzenböck connection which describes …

[HTML][HTML] Bouncing cosmology in modified Gauss–Bonnet gravity

K Bamba, AN Makarenko, AN Myagky, SD Odintsov - Physics Letters B, 2014 - Elsevier
We explore bounce cosmology in F (G) gravity with the Gauss–Bonnet invariant G. We
reconstruct F (G) gravity theory to realize the bouncing behavior in the early universe and …

Anisotropic universe models in gravity

ME Rodrigues, MJS Houndjo, D Saez-Gomez… - Physical Review D …, 2012 - APS
We investigate the cosmological reconstruction in an anisotropic universe for both the
homogeneous and inhomogeneous content of the universe. Special attention is given to …

Matter bounce loop quantum cosmology from gravity

SD Odintsov, VK Oikonomou - Physical Review D, 2014 - APS
Using the reconstruction method, we investigate which F (R) theories, with or without the
presence of matter fluids, can produce the matter bounce scenario of holonomy corrected …

Superbounce and loop quantum ekpyrotic cosmologies from modified gravity: F (R), F (G) and F (T) theories

SD Odintsov, VK Oikonomou, EN Saridakis - Annals of Physics, 2015 - Elsevier
We investigate the realization of two bouncing paradigms, namely of the superbounce and
the loop quantum cosmological ekpyrosis, in the framework of various modified gravities. In …

Gravitational waves in a cyclic Universe: resilience through cycles and vacuum state

M De Angelis, A Smith, W Giarè… - Journal of Cosmology …, 2024 - iopscience.iop.org
We present a generalised calculation for the spectrum of primordial tensor perturbations in a
cyclic Universe, making no assumptions about the vacuum state of the theory and …
