Utilising the master equation with source for perturbations of the SchwarzschildTangherlini solution, we construct perturbative solutions representing a black hole accelerated by a string in higher dimensions. We show that such solutions can be uniquely determined by a single function representing the local tension of the string, under natural asymptotic and regularity conditions. We further st...

A bstract We investigate the appearance of islands when a closed universe with gravity is entangled non-gravitating quantum system. use braneworlds in three-dimensional multiboundary wormhole geometries as model to explore what happens system has several components. The braneworld can be either completely contained entanglement wedge one systems or split between them. In former case, other lead...
