DOI: 10.1007/s10714-024-03342-5
Abstract: The status of the equivalence principle in modified symmetric teleparallel gravity is examined. In this theory, minimum length geodesics are distinct from autoparallel geodesics, that is, the “shortest” paths are not the “straightest” paths. We… read more here.

Abstract: In this paper, a noncommutative gravitational theory is constructed by applying Moyal deformation quantization and the Seiberg-Witten map to teleparallel gravity, a classical gravitational theory, as a gauge theory of local translational symmetry. Since our… read more here.

Abstract: We investigate the evolution of scalar perturbations in f(T) teleparallel gravity and its effects on the cosmic microwave background (CMB) anisotropy. The f(T) gravity generalizes the teleparallel gravity which is formulated on the Weitzenbock spacetime,… read more here.

DOI: 10.1088/1674-1137/ade49f
Abstract: Gravity is identical to curved spacetime. It is manifested by the curvature of a Riemannian spacetime in general relativity but by torsion or non-metricity in teleparallel gravity models. In this paper, we apply these multiple… read more here.

DOI: 10.1093/mnras/staf1492
Abstract: We investigate the viability of a modified teleparallel gravity model, specifically within the framework of f(T) gravity, by implementing two complementary approaches for cosmological parameter estimation. In the first approach, we incorporate the f(T) model… read more here.
