In this paper, we investigate the effect of the Generalized Uncertainty Principle (GUP) in the Casimir wormhole spacetime recently proposed by Garattini (Eur Phys J C 79: 951, 2019 ). In particular, we consider three types of GUP relations, firstly the Kempf, Mangano and Mann (KMM) model, secondly the Detournay, Gabriel and Spindel (DGS) model, and finally the so-called type II model for the GUP principle. To this end, we consider three specific models of the redshift function along with two… 

Traversable wormholes in f(R) massive gravity

This work chooses the shape function of the form b(r)=rexp(-α(r-r0)) with α and r0 being an arbitrary constant and a radius of the wormhole throat, respectively, and compute the volume integral quantifier to calculate the amount of the exotic matter near the constructed wormhole throats.

Ellis–Bronnikov Wormholes in Asymptotically Safe Gravity

In this paper, we investigate the simplest wormhole solution—the Ellis–Bronnikov one—in the context of the asymptotically safe gravity (ASG) at the Planck scale. We work with three models, which

Schwarzschild-like Wormholes in Asymptotically Safe Gravity

In this paper, we analyze the Schwarzschild-like wormhole in the Asymptotically Safe Gravity(ASG) scenario. The ASG corrections are implemented via renormalization group methods, which, as

Traversability of wormhole solutions in asymptotically safe gravity

It is showed that it is possible to have traversability with exotic and non-exotic matter, but the kind of matter is highly dependent on the wormhole’s parameters.

Casimir effect in space-times of rotating wormholes

We investigate the Casimir effect between parallel plates placed along a circular trajectory around the rotating Damour–Solodkhin (D–S) and Teo wormholes. This is made through the calculation of the

Casimir Wormholes in (2+1) Dimensions with Applications to the Graphene

In this paper we show that wormholes in (2+1) dimensions (3-D) cannot be sourced solely by both Casimir energy density and tension, differently from what happens in a 4-D scenario, in which case it

Dynamic wormhole geometries in hybrid metric-Palatini gravity

In this work, we analyse the evolution of time-dependent traversable wormhole geometries in a Friedmann–Lemaître–Robertson–Walker background in the context of the scalar–tensor representation of

Casimir effect in a Schwarzschild-like wormhole spacetime

In this paper, we investigate the role of gravito-inertial effects on the Casimir energy associated to a massless scalar field confined between two parallel plates orbiting a static and zero tidal

Wormholes in $$R^2$$R2-gravity within the f(R, T) formalism

The quadratic geometric and linear material corrections of this theory render the matter content of the wormhole remarkably able to obey the energy conditions.

Traversable wormholes satisfying the weak energy condition in third-order Lovelock gravity

In this paper, we consider third order Lovelock gravity with a cosmological constant term in an n-dimensional spacetime $\mathcal{M}^{4}\times \mathcal{K}^{n-4}$, where $\mathcal{K}^{n-4} $ is a

In this paper we have established an asymptotically conical Morris-Thorne wormhole solution with a global monopole charge in the framework of a $1+3$ dimensional gravity minimally coupled to a

Deformed Starobinsky model in gravity’s rainbow

In the context of gravity’s rainbow, we study the deformed Starobinsky model in which the deformations take the form $$f(R)\sim R^{2(1-\alpha )}$$f(R)∼R2(1-α), with R and $$\alpha $$α being the Ricci

We find a new traversable wormhole solution in the framework of the bumblebee gravity theory in which the Lorentz symmetry violation arises from the dynamics of the bumblebee vector field

In this paper, we study the Starobinsky model of inflation in the context of gravity's rainbow theory. We propose that gravity rainbow functions can be written in the power-law form of the Hubble
