On the instability of charged wormholes supported by a ghost scalar field
J. A. Gonzalez, F. S. Guzman, O. Sarbach
In previous work, we analyzed the linear and nonlinear stability of static, spherically symmetric wormhole solutions to Einstein's field equations coupled to a massless ghost scala…
On Wormholes supported by phantom energy
J. A. Gonzalez, F. S. Guzman, N. Montelongo-Garcia +1
By a combination of analytical and numerical techniques, we demonstrate the existence of spherical, asymptotically flat traversable wormholes supported by exotic matter whose stres…
Accretion of phantom scalar field into a black hole
J. A. Gonzalez, F. S. Guzman
Using numerical methods we present the first full nonlinear study of phantom scalar field accreted into a black hole. We study different initial configurations and find that the ac…
