Page curves on codim-m and charged branes

Abstract This paper investigates Page curves on the branes with higher codimensions and charges. We study two kinds of doubly holographic modes, AdS/dCFT cone holography. In AdS/dCFT, gravitations brane are massive, black hole codim-m is coupled non-gravitational bath AdS boundary. Following standard approach, we derive curve for eternal holes. On other hand, holography includes massless graviton brane, becomes gravitating. By adding suitable DGP gravity end-of-the-world recover non-trivial entanglement islands curves, which strongly support that island consistent gravity. Finally, analyze effects charges find that, as increase, time increases, parameter space widens.
