Constraining braneworlds with entanglement entropy

H Geng, A Karch, C Perez-Pardavila, L Randall… - SciPost Physics, 2023 - scipost.org
We propose swampland criteria for braneworlds viewed as effective field theories of defects
coupled to semiclassical gravity. We do this by exploiting their holographic interpretation …

Replica wormholes and entanglement islands in the Karch-Randall braneworld
