Thin-shell wormholes from regular charged black holes
F. Rahaman, K A Rahman, Sk. A Rakib +1
We investigate a new thin-shell wormhole constructed by surgically grafting two regular charged black holes arising from the action using nonlinear electrodynamics coupled to gener…
Theoretical construction of Morris-Thorne wormholes compatible with quantum field theory
Peter K. F. Kuhfittig
This paper completes and extends some earlier studies by the author to show that Morris-Thorne wormholes are compatible with quantum field theory. The strategy is to strike a balan…
Quintom wormholes
Peter K. F. Kuhfittig, Farook Rahaman, Ashis Ghosh
The combination of quintessence and phantom energy in a joint model is referred to as quintom dark energy. This paper discusses traversable wormholes supported by such quintom matt…
Wormholes supported by polytropic phantom energy
Mubasher Jamil, Peter K. F. Kuhfittig, Farook Rahaman +1
It is generally agreed that the acceleration of the Universe can best be explained by the presence of dark or phantom energy. The equation of state of the latter shows that the nul…
A single model of traversable wormholes supported by generalized phantom energy or Chaplygin gas
Peter K. F. Kuhfittig
This paper discusses a new variable equation of state parameter leading to exact solutions of the Einstein field equations describing traversable wormholes. In addition to generali…
An unexpected topological censor
Peter K. F. Kuhfittig
Morris-Thorne wormholes with a cosmological constant Λhave been studied extensively, even allowing Λto be replaced by a space variable scalar. These wormholes cannot exist, however…
