Bounds on CFT correlations from the thermal partition function
Fikret Ceyhan, Thomas Faulkner
We discuss upper bounds on the mutual information for disjoint spherical regions of the CFT vacuum. To prove our bounds, we utilize the modular nuclearity condition, which is in tu…

Recovering the QNEC from the ANEC
Fikret Ceyhan, Thomas Faulkner
We study relative entropy in QFT, comparing the vacuum state to a special family of purifications determined by an input state and constructed using relative modular flow. We use t…
