In this study, a bulk wormhole geometry interpolating between horizons of differing size is defined and characteristics of the Hubeny-Rangamani-Takayanagi surface in these geometries are determined. This construction is dual to black hole mesostates, representing an intermediate coarse-graining of states between black hole microstates and the full black hole state. The distinguishability of these objects is analyzed using holographic Holevo information techniques, showing novel phase transition behavior for such systems.
We define a bulk wormhole geometry interpolating between horizons of differing size and determine characteristics of the Hubeny-Rangamani-Takayanagi surface in these geometries. This construction is dual to black hole mesostates, an intermediate coarse-graining of states between black hole microstates and the full black hole state. We analyze the distinguishability of these objects using the recently derived holographic Holevo information techniques, demonstrating novel phase transition behavior for such systems.
