Traversable wormhole geometries in gravity

Z Hassan, S Mandal, PK Sahoo - Fortschritte der Physik, 2021 - Wiley Online Library
The current interests in the universe motivate us to go beyond Einstein's General theory of
relativity. One of the interesting proposals comes from a new class of teleparallel gravity …

Traversable wormhole inspired by non-commutative geometries in f (Q) gravity with conformal symmetry

G Mustafa, Z Hassan, PK Sahoo - Annals of Physics, 2022 - Elsevier
This article is based on the study of wormhole geometries in the context of symmetric
teleparallel gravity or f (Q) gravity, where Q is the non-metricity scalar, and it is responsible …

Static traversable wormhole solutions in f (R, ℒm) gravity

Novel junction conditions in f G, T modified gravity

MZ Bhatti, M Yousaf, Z Yousaf - General Relativity and Gravitation, 2023 - Springer
This manuscript aims to establish the gravitational junction conditions for the f (G, T) gravity.
In this gravitational theory, f is an arbitrary function of Gauss-Bonnet invariant G and the …

f (Q, T) gravity models with observational constraints

S Arora, SKJ Pacif, S Bhattacharjee… - Physics of the Dark …, 2020 - Elsevier
The paper presents late time cosmology in f (Q, T) gravity where the dark energy is purely
geometric in nature. We start by employing a well motivated f (Q, T) gravity model, f (Q, T)= m …

Strong gravitational lensing by wormholes

R Shaikh, P Banerjee, S Paul… - Journal of Cosmology and …, 2019 - iopscience.iop.org
We study strong gravitational lensing by a class of static wormhole geometries. Analytical
approaches to the same are developed, and the results differ substantially from strong …

Spherically symmetric traversable wormholes in the torsion and matter coupling gravity formalism
