Looking at extremal black holes from very far away
Maciej Kolanowski, Donald Marolf, Ilija Rakic +2
Near-extremal black holes are subject to large quantum effects, which modify their low-temperature thermodynamic behavior. Hitherto, these quantum effects were analyzed by separati…
Are wormholes generic with large sources?
Xiaoyi Liu, Donald Marolf, Jorge E. Santos
Euclidean path integrals can be used to prepare states of a Lorentzian QFT. So long as any sources are turned off on the surface, the resulting Lorentzian states all belong t…
Euclidean wormholes stability analysis revisited
Donald Marolf, Bruno Missoni
Previous studies of linearized stability of asymptotically flat Euclidean axion wormholes found that symmetric modes suffered from divergences. We show that such divergences were a…
Euclidean and complex geometries from real-time computations of gravitational Rényi entropies
Jesse Held, Xiaoyi Liu, Donald Marolf +1
Gravitational Rényi computations have traditionally been described in the language of Euclidean path integrals. In the semiclassical limit, such calculations are governed by Eucli…
