Quantum chaos and pole skipping in two-dimensional conformal perturbation theory
Curtis T. Asplund, Sebastian Fischetti, Alexandra Miller +1
We analyze pole skipping of stress tensor two-point functions in two-dimensional quantum field theories perturbed away from conformality by a relevant deformation. The retarded two…
A Tale of Two Saddles
Venkatesa Chandrasekaran, Netta Engelhardt, Sebastian Fischetti +1
We find a new on-shell replica wormhole in a computation of the generating functional of JT gravity coupled to matter. We show that this saddle has lower action than the disconnect…
A Surprising Similarity Between Holographic CFTs and a Free Fermion in Dimensions
Krai Cheamsawat, Sebastian Fischetti, Lucas Wallis +1
We compare the behavior of the vacuum free energy (i.e. the Casimir energy) of various -dimensional CFTs on an ultrastatic spacetime as a function of the spatial geometry. T…
More of the Bulk from Extremal Area Variations
Ning Bao, ChunJun Cao, Sebastian Fischetti +2
It was shown recently, building on work of Alexakis, Balehowksy, and Nachman that the geometry of (some portion of) a manifold with boundary is uniquely fixed by the areas of a fol…
Free Energy from Replica Wormholes
Netta Engelhardt, Sebastian Fischetti, Alexander Maloney
Euclidean wormholes -- geometries which connect disconnected boundaries -- present a challenge to a standard quantum mechanical interpretation of the theory. One potential resoluti…
Does the Round Sphere Maximize the Free Energy of (2+1)-Dimensional QFTs?
Sebastian Fischetti, Lucas Wallis, Toby Wiseman
We examine the renormalized free energy of the free Dirac fermion and the free scalar on a (2+1)-dimensional geometry , with having spherical topology and…
