“…gravity coupled with a dilaton and the above NED model was studied where the dynamical vacuum energy and confinement have been investigated. Very recently this model was coupled with gravity in a magnetic field regime to construct a sort of thin-shell wormhole that is supported by a cloud of exotic dust [11]. There are other related studies that can be seen in [12][13][14][15] and the references therein.…”

In this study, we present a generalized version of the specific nonlinear electrodynamic model introduced by Guendelman [PLB640(2006)201] as a result of spontaneously breaking the scale invariance of Maxwell's linear theory. The generalized model involves a new integer parameter $n$ so that $n=2$ reproduces Guendelman's model. Although with each $n$ in principle there exist a new model but technically only $n=2$ and $n=3$ yield a closed analytical expression.

The traversable wormholes are fascinating as the shortcuts in spacetime. This work discusses the geometry of a traversable wormhole with a string cloud as a source in rainbow gravity. The field equations are developed and solved to obtain the wormhole's shape function, cloud's mass density, and string tension. We have calculated the shape function and make it specific to study the dynamics for toy model. Based on the three well-known pairs of rainbow functions (mentioned by Ali and Khalil, 2015), the string cloud's dynamical variables including mass density and string tension are graphically presented. The corresponding energy conditions are also visually depicted. It is found that the source matter (string cloud) of the traversable wormhole must be exotic. However, the positive values of the string tension led to the presence of Casimir and dark energy effects. It is found that the toy model respects the null energy condition for a single pair of rainbow functions, i.e., Rainbow Function Type II. We have concluded that in rainbow gravity theory, the traversable wormhole solutions originating from a string cloud requires the presence of exotic matter to achieve a stable structure.
