DOI: 10.1007/s10509-020-3743-5
Abstract: In the present article, models of traversable wormholes within the $f(R, T)$ modified gravity theory, where $R$ is the Ricci scalar and $T$ is the trace of the energy-momentum tensor, are investigated. We have presented… read more here.

DOI: 10.1016/j.aop.2020.168295
Abstract: Abstract To find more deliberate f ( R , T ) astrophysical solutions, we proceed by studying wormhole geometries under the assumption of spherical symmetry and the existence of a conformal Killing symmetry to attain… read more here.

DOI: 10.1063/5.0148762
Abstract: It is known that static traversable wormholes in Einstein gravity are supported by matter that violates null energy conditions (NEC). Essentially, such wormholes will be characterized by a central throat with anisotropic matter lining the… read more here.

DOI: 10.1103/physrevd.100.044011
Abstract: In general relativity, traversable wormholes are possible provided they do not represent shortcuts in the spacetime. Einstein equations, together with the achronal averaged null energy condition, demand to take longer for an observer to go… read more here.

DOI: 10.1103/physrevd.105.044058
Abstract: Bubble universes and traversable wormholes in general relativity can be realized as two sides of the same concept. To exemplify it, we find, display, and study in a unified manner a MinkowskiMinkowski closed universe and… read more here.
