1203.0523 (Orfeu Bertolami et al.)

Traversable Wormholes and Time Machines in non-minimally coupled
curvature-matter $f(R)$ theories
   [PDF]

Orfeu Bertolami, Ricardo Zambujal Ferreira
We obtain traversable wormhole and time machine solutions of the field equations of an alternative of gravity with non-minimally curvature-matter coupling. Our solutions exhibit a non-trivial redshift function and allow for matter that satisfy the dominant energy condition.
