Islands for entanglement negativity in communicating black holes

We obtain the holographic entanglement negativity for bipartite mixed states at a finite temperature in baths described by conformal field theories dual to configurations involving two communicating black holes braneworld geometry. In this context, we analyze state structure characterized information transfer between holes. The model corresponds configuration of dimensional eternal Jackiw-Teitelboim (JT) geometry Planck branes coupled through shared bath systems ${\mathrm{CFT}}_{2}\mathrm{s}$. Our results reproduce analogue Page curves obtained earlier context random matrix theory and from geometric evaporation JT hole configurations.
