Positivity of the gravitational path integral implies the axionic weak gravity conjecture
Gabriele Di Ubaldo, Luca V. Iliesiu, Henry W. Lin +1
The gravitational path integral can compute inner products between different states of open and closed universes. To have a well-defined Hilbert space, these inner products should…
Puzzles in 3D Off-Shell Geometries via VTQFT
Cynthia Yan
We point out a difficulty with a naive application of Virasoro TQFT methods to compute path integrals for two types of off-shell 3-dimensional geometries. Maxfield-Turiaci proposed…
Cusps in 3d gravity
Douglas Stanford, Cynthia Yan
Three dimensional hyperbolic manifolds have accumulation points in the spectrum of their volumes, leading to a divergence in the sum over topologies. The limit points are cusped hy…
Revised QCD effects on the forward-backward asymmetry in collisions
David d'Enterria, Cynthia Yan
The forward-backward (FB) asymmetry of quarks in collisions at the Z pole measured at LEP, , remains today one of the electroweak…
Constructing all BPS black hole microstates from the gravitational path integral
Jan Boruch, Luca V. Iliesiu, Cynthia Yan
Understanding how to prepare and count black hole micro-states by using the gravitational path integral is one of the most important problems in quantum gravity. Nevertheless, a st…
How the Hilbert space of two-sided black holes factorises
Jan Boruch, Luca V. Iliesiu, Guanda Lin +1
In AdS/CFT, two-sided black holes are described by states in the tensor product of two Hilbert spaces associated with the two asymptotic boundaries of the spacetime. Understanding…
