Abstract:
A brief review is given of scalar field theories with second-derivative Lagrangians yielding second-order field equations. Some of these theories permit solutions that violate the null energy condition but otherwise show no obvious inconsistencies. The use of these theories in constructing cosmological scenarios and in the context of a laboratory-created universe is illustrated with examples.
