$f (R)$ Gravity Wormholes sourced by a Phantom Scalar Field

Thanasis Karakasis, Eleftherios Papantonopoulos, Christoforos Vlachos

We derive an exact wormhole spacetime supported by a phantom scalar field in the context of $f (R)$ gravity. Without specifying the form of the $f (R)$ function, the scal…

Exact Black Hole Solutions with a Conformally Coupled Scalar Field and Dynamic Ricci Curvature in $f (R)$ Gravity Theories

Thanasis Karakasis, Eleftherios Papantonopoulos, Zi-Yu Tang +1

We report exact black hole solutions in asymptotically flat or (A)dS four-dimensional spacetime with a conformally coupled self-interacting scalar field in $f (R)$ gravity. We first…

Black holes of $(2 + 1)$ -dimensional $f (R)$ gravity coupled to a scalar field

Thanasis Karakasis, Eleftherios Papantonopoulos, Zi-Yu Tang +1

We consider $f (R)$ gravity theories in the presence of a scalar field minimally coupled to gravity with a self-interacting potential in $(2 + 1)$ -dimensions. Without specifying the f…
