On Coupling NEC-Violating Matter to Gravity
arXiv:1503.07950 · doi:10.1016/j.physletb.2015.03.020
Abstract
We show that effective theories of matter that classically violate the null energy condition cannot be minimally coupled to Einstein gravity without being inconsistent with both string theory and black hole thermodynamics. We argue however that they could still be either non-minimally coupled or coupled to higher-curvature theories of gravity.
