Revisiting wormhole energy conditions in Riemann-Cartan spacetimes and under Weyl transformations
Fayçal Hammad, Étienne Massé, Patrick Labelle
We show that the violation of the null energy condition by matter, required by traversable wormholes, can be removed in spacetimes with torsion. In addition, we show that this viol…

Black hole mechanics and thermodynamics in the light of Weyl transformations
Fayçal Hammad, Étienne Massé, Patrick Labelle
The fate of black hole thermodynamics under Weyl transformations is investigated by going back to the laws of black hole mechanics. It is shown that the transformed surface gravity…

Revisiting the analogue of the Jebsen-Birkhoff theorem in Brans-Dicke gravity
Valerio Faraoni, Faycal Hammad, Adriana M. Cardini +1
We report the explicit form of the general static, spherically symmetric, and asymptotically flat solution of vacuum Brans-Dicke gravity in the Jordan frame, assuming that the Bran…
