Wormholes and Time-Machines in Nonminimally Coupled Matter-Curvature Theories of Gravity

Abstract

In this work we show the existence of traversable wormhole and time-machine solutions in a modified theory of gravity where matter and curvature are nonminimally coupled. Those solutions present a nontrivial redshift function and exist even in the presence of ordinary matter which satisfies the dominant energy condition.
