Information Transfer with a Gravitating Bath
Hao Geng, Andreas Karch, Carlos Perez-Pardavila +4
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 na…
Holographic duality for Ising CFT with boundary
Andreas Karch, Zhu-Xi Luo, Hao-Yu Sun
We extend the holographic duality between 3d pure gravity and the 2d Ising CFT proposed in [Phys. Rev. D 85 (2012) 024032] to CFTs with boundaries. Besides the usual asymptotic bou…
Reduced Conformal Symmetry
Andreas Karch, Amir Raz
We construct field theories in dimensions with multiple conformal symmetries acting on only one of the spatial directions. These can be considered a conformal extension to "s…
Massive Islands
Hao Geng, Andreas Karch
We comment on the role of the graviton mass in recent calculations of the Page curve using holographic ideas. All reliable calculations of the Page curve in more than 2+1 spacetime…
Geometries with mismatched branes
Andreas Karch, Lisa Randall
We study Randall-Sundrum two brane setups with mismatched brane tensions. For the vacuum solutions, boundary conditions demand that the induced metric on each of the branes is eith…
