The minimal entanglement wedge cross section in the GMMG/GCFT flat holography

Abstract: We focus on a proper candidate for the entanglement wedge in asymptotically flat bulk geometries that are described by the generalized minimal massive gravity (GMMG) in the context of the flat holography. To this end, we describe the boundary by two dimensional Galilean conformal field theory (GCFT) at the bipartite mixed state of the two disjoint intervals. We make a conjecture on the minimal entanglement wedge cross section (EWCS) and we find that the results are consistent with the previous computations on the holographic entanglement negativity.
