“…It is interesting to generalize the discussions to evaporating black holes. See some interesting progress in [53]. Fourth, there is also a massless gravitational mode on the branes of cone holography [49], which generalizes wedge holography to codim-n defects.…”

Entanglement islands play an essential role in the recent breakthrough in resolving the black hole information paradox. However, whether entanglement islands can exist in massless gravity theories is controversial. It is found that entanglement islands disappear in the initial model of wedge holography with massless gravity on the brane. As a result, the entanglement entropy of Hawking radiation becomes a time-independent constant, and there is no Page curve. In this paper, we recover massless entanglement islands in wedge holography with suitable DGP gravity or higher derivative gravity on the branes. We study two typical cases. In the first case, we consider a black hole on the strong-gravity brane and a bath on the weak-gravity brane. It is similar to the usual double holography with non-gravitational baths. In the second case, we discuss two black holes on the two branes with the same gravitational strength. We recover massless entanglement islands and non-trivial Page curves in both cases. We also argue that the entanglement island is consistent with massless gravity. Our results strongly support that entanglement islands can exist in long-range theories of gravity.

“…One of the major advantages of AdS/BCFT is that the computation of entanglement entropy in the AdS/BCFT is straightforward, such that the minimal surface in the holographic entanglement entropy [12][13][14] can end on the end-of-the-world brane as first noted in [9,10] (see also [15]). This was recently employed to analyze black hole evaporation processes to derive the Page curve [16], where the Island prescription [17,18] is expected from the brane-world holography [19][20][21][22][23][24][25][26][27][28][29][30][31]. For further applications of AdS/BCFT to black hole information problem refer to e.g.…”

In this paper, we study the dynamics of end-of-the-world (EOW) branes in AdS with scalar fields localized on the branes as a new class of gravity duals of CFTs on manifolds with boundaries. This allows us to construct explicit solutions dual to boundary RG flows. We also obtain a variety of annulus-like or cone-like shaped EOW branes, which are not possible without the scalar field. We also present a gravity dual of a CFT on a strip with two different boundary conditions due to the scalar potential, where we find the confinement/deconfinement-like transition as a function of temperature and the scalar potential. Finally, we point out that this phase transition is closely related to the measurement-induced phase transition, via a Wick rotation.
