How negative can null energy be in large N CFTs?
Jackson R. Fliss, Ben Freivogel, Eleni-Alexandra Kontou +1
Smeared null energy has been shown to be bounded from below for free minimally coupled quantum field theories. This is not the case for conformally coupled free bosonic theories wh…

Non-minimal coupling, negative null energy, and effective field theory
Jackson R. Fliss, Ben Freivogel, Eleni-Alexandra Kontou +1
The non-minimal coupling of scalar fields to gravity has been claimed to violate energy conditions, leading to exotic phenomena such as traversable wormholes, even in classical the…
