On the N-partite information in Conformal Field Theory

Abstract: In this talk, I will present a general procedure for computing the N-partite information in the ground state of a conformal field theory for N-disjoint spheres in the large separation regime. I will motive this computation as part of the general program of describing the CFT from entanglement related quantities. Then, I will apply the general procedure to rederive known formulas for the mutual information and tri-partite information as well as to present a new result pertaining the four-partite information in the large separation regime. I then show good agreement between our analytic results and lattice computations for the free scalar field in $d=3$. Finally, I close with an explicit check within the context of our computations of the Faulkner, Lewkowycz and Maldacena (FLM) prescription in holographic conformal field theories.
