Abstract

I will describe recent work which defines a class of multi-party measures of entanglement which are characterized by tensorial contractions of copies of a density matrix with respect to an arbitrary finite group symmetry.

For AdS3/CFT2 they can be determined by both boundary replica trick calculations of twist operators and by bulk quotients of Euclidean AdS3 by Kleinian groups. The technology developed allows for the determination of all such measures which can preserve bulk replica symmetry.

I will provide several explicit examples including a complete classification of measures with genus zero and one replica surfaces.
