Averaged Null Energy Condition from Causality
Thomas Hartman, Sandipan Kundu, Amirhossein Tajdini
Unitary, Lorentz-invariant quantum field theories in flat spacetime obey microcausality: commutators vanish at spacelike separation. For interacting theories in more than two dimen…
Einstein gravity 3-point functions from conformal field theory
Nima Afkhami-Jeddi, Thomas Hartman, Sandipan Kundu +1
We study stress tensor correlation functions in four-dimensional conformal field theories with large and a sparse spectrum. Theories in this class are expected to have local ho…
Black Hole Collapse in the 1/c Expansion
Tarek Anous, Thomas Hartman, Antonin Rovai +1
We present a first-principles CFT calculation corresponding to the spherical collapse of a shell of matter in three dimensional quantum gravity. In field theory terms, we describe…
A New Spin on Causality Constraints
Thomas Hartman, Sachin Jain, Sandipan Kundu
Causality in a shockwave state is related to the analytic properties of a four-point correlation function. Extending recent results for scalar probes, we show that this constrains…
