Selected topics in scalar–tensor theories and beyond

I Quiros - International Journal of Modern Physics D, 2019 - World Scientific
Scalar fields have played an important role in the development of the fundamental theories
of physics as well as in other branches of physics such as gravitation and cosmology. For a …

Wormhole geometries in modified theories of gravity

FSN Lobo, MA Oliveira - Physical Review D—Particles, Fields, Gravitation, and …, 2009 - APS
In this work, we construct traversable wormhole geometries in the context of f (R) modified
theories of gravity. We impose that the matter threading the wormhole satisfies the energy …

Modeling wormholes in gravity

P Moraes, PK Sahoo - Physical Review D, 2017 - APS
In this work, we propose the modeling of static wormholes within the f (R, T) extended theory
of gravity perspective. We present some models of wormholes, which are constructed from …

[HTML][HTML] Non-exotic traversable wormhole solutions in linear gravity

J Luís Rosa, PM Kull - The European Physical Journal C, 2022 - Springer
In this work we analyze traversable wormhole solutions in the linear form of\(f\left (R,
T\right)= R+\lambda T\) gravity satisfying the Null, Weak, Strong, and Dominant Energy …

[HTML][HTML] Non-local gravity wormholes

S Capozziello, N Godani - Physics Letters B, 2022 - Elsevier
Abstract We consider Non-local Gravity in view to obtain stable and traversable wormhole
solutions. In particular, the class of Non-local Integral Kernel Theories of Gravity, with the …

Analytical general solutions for static wormholes in f (R, T) gravity

P Moraes, RAC Correa, RV Lobato - Journal of Cosmology and …, 2017 - iopscience.iop.org
Originally proposed as a tool for teaching the general theory of relativity, wormholes are
today approached in many different ways and are seeing as an efficient alternative for …

Morris-Thorne wormholes with a cosmological constant

JPS Lemos, FSN Lobo, SQ de Oliveira - Physical Review D, 2003 - APS
First, the ideas introduced in the wormhole research field since the work of Morris and
Thorne are reviewed, namely, the issues of energy conditions, wormhole construction …

Dynamic wormholes, antitrapped surfaces, and energy conditions

D Hochberg, M Visser - Physical Review D, 1998 - APS
It is by now apparent that topology is too crude a tool to accurately characterize a generic
traversable wormhole. In two earlier papers we developed a complete characterization of …

Relativistic wormholes in extended teleparallel gravity with minimal matter coupling

G Mustafa, SK Maurya, I Hussain - Fortschritte der Physik, 2023 - Wiley Online Library
This study explores the wormhole solutions utilizing the notion of conformal symmetry in the
background of the f (τ, T) f(τ,T) gravity. The exact shape functions are calculated using the …

Wormhole configuration with viable equation of state in f (Q) gravity

S Kiroriwal, J Kumar, SK Maurya, S Ray - Physics of the Dark Universe, 2024 - Elsevier
In this paper, we present asymptotically flat wormhole geometries in the context of f (Q)
gravity theory, where Q is non-metricity scalar, by assuming a particular equation of state …
