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 …

Reconstructing teleparallel gravity with cosmic structure growth and expansion rate data

In this work, we use a combined approach of Hubble parameter data together with redshift-
space-distortion (fσ 8) data, which together are used to reconstruct the teleparallel gravity …

Gravitational-wave propagation and polarizations in the teleparallel analog of Horndeski gravity

S Bahamonde, M Hohmann, M Caruana… - Physical Review D, 2021 - APS
Gravitational waves (GWs) have opened a new window on fundamental physics in a number
of important ways. The next generation of GW detectors may reveal more information about …

Symmetric teleparallel Gauss-Bonnet gravity and its extensions

JM Armaleo, S Bahamonde, G Trenkler, LG Trombetta - Physical Review D, 2023 - APS
General teleparallel theories assume that curvature is vanishing in which case gravity can
be solely represented by torsion and/or nonmetricity. Using differential form language, we …

Ghost and Laplacian instabilities in teleparallel Horndeski gravity

S Capozziello, M Caruana, JL Said… - Journal of Cosmology …, 2023 - iopscience.iop.org
Teleparallel geometry offers a platform on which to build up theories of gravity where torsion
rather than curvature mediates gravitational interaction. The teleparallel analogue of …

Spontaneous scalarization of black holes in Gauss-Bonnet teleparallel gravity

S Bahamonde, DD Doneva, L Ducobu, C Pfeifer… - Physical Review D, 2023 - APS
In this paper, we find new scalarized black holes by coupling a scalar field with the Gauss-
Bonnet invariant in teleparallel gravity. The teleparallel formulation of this theory uses …

Thick brane in gravity

ARP Moreira, JEG Silva, FCE Lima, CAS Almeida - Physical Review D, 2021 - APS
In this paper we explore the five-dimensional f (T, B) teleparallel modified gravity with f 1 (T,
B)= T+ k 1 B n 1 and f 2 (T, B)= B+ k 2 T n 2 in the brane scenario. Asymptotically, the bulk …

Gibbons-Hawking-York boundary terms and the generalized geometrical trinity of gravity

J Erdmenger, B Heß, R Meyer, I Matthaiakakis - Physical Review D, 2024 - APS
General relativity (GR) as described in terms of curvature by the Einstein-Hilbert action is
dynamically equivalent to theories of gravity formulated in terms of spacetime torsion or …

Comparing inflationary models in extended Metric-Affine theories of gravity

S Capozziello, M Shokri - Physics of the Dark Universe, 2024 - Elsevier
We study slow-roll inflation as a common feature in Metric-affine Theories of Gravity. In
particular, we take into account extended metric, teleparallel and symmetric-teleparallel …
