Replica wormholes for an evaporating 2D black hole
Kanato Goto, Thomas Hartman, Amirhossein Tajdini
Quantum extremal islands reproduce the unitary Page curve of an evaporating black hole. This has been derived by including replica wormholes in the gravitational path integral, but…
Islands in cosmology
Thomas Hartman, Yikun Jiang, Edgar Shaghoulian
A quantum extremal island suggests that a region of spacetime is encoded in the quantum state of another system, like the encoding of the black hole interior in Hawking radiation.…
The entropy of Hawking radiation
Ahmed Almheiri, Thomas Hartman, Juan Maldacena +2
In this review, we describe recent progress on the black hole information problem that involves a new understanding of how to calculate the entropy of Hawking radiation. We show ho…
Free partition functions and an averaged holographic duality
Nima Afkhami-Jeddi, Henry Cohn, Thomas Hartman +1
We study the torus partition functions of free bosonic CFTs in two dimensions. Integrating over Narain moduli defines an ensemble-averaged free CFT. We calculate the averaged parti…
High-dimensional sphere packing and the modular bootstrap
Nima Afkhami-Jeddi, Henry Cohn, Thomas Hartman +2
We carry out a numerical study of the spinless modular bootstrap for conformal field theories with current algebra , or equivalently the linear programming bo…
Islands in Asymptotically Flat 2D Gravity
Thomas Hartman, Edgar Shaghoulian, Andrew Strominger
The large-N limit of asymptotically flat two-dimensional dilaton gravity coupled to N free matter fields provides a useful toy model for semiclassical black holes and the informati…
