چکیده
We derive an exact wormhole spacetime supported by a phantom scalar field in the context of $f({\sf R})$ gravity. Without specifying form function, self-interacts with mass term potential that is derived from equation and resulting model purely it free ghosts avoids tachyonic instability.

Tachyonic field interacting with Scalar (Phantom) Field
In this letter, we have considered the universe is filled with the mixture of tachyonic field and scalar or phantom field. If the tachyonic field interacts with scalar or phantom field, the interaction term decays with time and the energy for scalar field is transferred to tachyonic field or the energy for phantom field is transferred to tachyonic field. The tachyonic field and scalar field pot...
متن کاملCharged Black Holes and Unusual Wormholes in Scalar-tensor Gravity
We consider static, spherically symmetric, electrically or/and magnetically charged configurations of a minimally coupled scalar field with an arbitrary potential V (φ) in general relativity. Using the inverse problem method, we obtain a four-parameter family of asymptotically dS, flat and AdS solutions, including those with naked singularities and both extreme and non-extreme black-hole (BH) s...
متن کاملOnce again on thin-shell wormholes in scalar-tensor gravity
It has been recently proved in a general form [1] that no wormholes can be formed in any scalartensor theory (STT) of gravity in which the non-minimal coupling function f(Φ) is everywhere positive and the scalar field Φ itself is not a ghost if matter sources of gravity respect the Null Energy Condition (NEC). In order to construct any viable and stable wormhole solution, attempts have been rec...
متن کاملPhantom energy traversable wormholes
It has been suggested that a possible candidate for the present accelerated expansion of the Universe is “phantom energy”. The latter possesses an equation of state of the form ω ≡ p/ρ < −1, consequently violating the null energy condition. As this is the fundamental ingredient to sustain traversable wormholes, this cosmic fluid presents us with a natural scenario for the existence of these exo...
متن کاملPhantom Cosmology with a Nonlinear Born - Infeld type Scalar Field
Recent progress in theoretical physics suggests that the dark energy in the universe result from the Born-Infeld (B-I) type scalar field of string theory. The universe of B-I type scalar field with potential can undergo a phase of accelerated expansion. The corresponding equation of state parameter lies in the range of −1 < w < − 1 3. The equation of state parameter of B-I type scalar field wit...
