# Information Transfer with a Gravitating Bath

@article{Geng2020InformationTW, title={Information Transfer with a Gravitating Bath}, author={Hao Geng and Andreas Karch and Carlos Perez-Pardavila and S. Raju and Lisa Randall and Marcos Riojas and Sanjit Shashi}, journal={arXiv: High Energy Physics - Theory}, year={2020} }

Late-time dominance of entanglement islands plays a critical role in addressing the information paradox for black holes in AdS coupled to an asymptotic non-gravitational bath. A natural question is how this observation can be extended to gravitational systems. To gain insight into this question, we explore how this story is modified within the context of Karch-Randall braneworlds when we allow the asymptotic bath to couple to dynamical gravity. We find that because of the inability to separate…
