Wormhole geometries in f(Q) gravity and the energy conditions

A Banerjee, A Pradhan, T Tangphati… - The European Physical …, 2021 - Springer
Following the recent theory of f (Q) gravity, we continue to investigate the possible existence
of wormhole geometries, where Q is the non-metricity scalar. Recently, the non-metricity …

Phantom energy traversable wormholes

FSN Lobo - Physical Review D—Particles, Fields, Gravitation, and …, 2005 - APS
It has been suggested that a possible candidate for the present accelerated expansion of the
Universe is “phantom energy”. The latter possesses an equation of state of the form ω≡ p/ρ< …

[图书][B] Extensions of f (R) Gravity: Curvature-Matter Couplings and Hybrid Metric-Palatini Theory

T Harko, FSN Lobo - 2018 - books.google.com
Recent cosmological observations have posed a challenge for traditional theories of gravity:
what is the force driving the accelerated expansion of the universe? What if dark energy or …

Quantum corrected charged thin-shell wormholes surrounded by quintessence

F Javed, A Waseem, B Almutairi - The European Physical Journal C, 2023 - Springer
In this manuscript, we inspect the stable geometry of thin-shell wormholes in the framework
of static, spherically-symmetric quantum corrected charged black hole solution bounded by …

Stable dark energy stars

FSN Lobo - Classical and Quantum Gravity, 2006 - iopscience.iop.org
The gravastar picture is an alternative model to the concept of a black hole, where there is
an effective phase transition at or near where the event horizon is expected to form, and the …

Wormholes supported by hybrid metric-Palatini gravity

S Capozziello, T Harko, TS Koivisto, FSN Lobo… - Physical Review D …, 2012 - APS
Recently, a modified theory of gravity was presented, which consists of the superposition of
the metric Einstein-Hilbert Lagrangian with an f (R) term constructed à la Palatini. The theory …

Einstein-Gauss-Bonnet traversable wormholes satisfying the weak energy condition

MR Mehdizadeh, MK Zangeneh, FSN Lobo - Physical Review D, 2015 - APS
In this paper, we explore higher-dimensional asymptotically flat wormhole geometries in the
framework of Gauss-Bonnet (GB) gravity and investigate the effects of the GB term, by …

Stability of thin-shell wormhole in 4D Einstein–Gauss–Bonnet gravity

N Godani, DV Singh, GC Samanta - Physics of the Dark Universe, 2022 - Elsevier
In this paper, we construct a thin-shell wormhole (TSW) in 4 D Einstein–Gauss–Bonnet
gravity (EGB) and examine the stability condition of the wormhole (WH) by using the linear …

Dynamic thin-shell black-bounce traversable wormholes

FSN Lobo, A Simpson, M Visser - Physical Review D, 2020 - APS
Based on the recently introduced black-bounce spacetimes, we shall consider the
construction of the related spherically symmetric thin-shell traversable wormholes within the …

Stability of phantom wormholes

FSN Lobo - Physical Review D—Particles, Fields, Gravitation, and …, 2005 - APS
It has recently been shown that traversable wormholes may be supported by phantom
energy. In this work phantom wormhole geometries are modeled by matching an interior …
