On the Architecture of Spacetime Geometry
Eugenio Bianchi, Robert C. Myers
We propose entanglement entropy as a probe of the architecture of spacetime in quantum gravity. We argue that the leading contribution to this entropy satisfies an area law for any…
Horizons cannot save the Landscape
Iosif Bena, Alex Buchel, Oscar J. C. Dias
Solutions with anti-D3 branes in a Klebanov-Strassler geometry with positive charge dissolved in fluxes have a certain singularity corresponding to a diverging energy density of th…
Dynamics of holographic thermalization
Walter H. Baron, Damian Galante, Martin Schvellinger
Dynamical evolution of thin shells composed by different kinds of degrees of freedom collapsing within asymptotically AdS spaces is explored with the aim of investigating models of…
DBI Realizations of the Pseudo-Conformal Universe and Galilean Genesis Scenarios
Kurt Hinterbichler, Austin Joyce, Justin Khoury +1
The pseudo-conformal universe is an alternative to inflation in which the early universe is described by a conformal field theory on approximately flat space-time. The fields devel…
Subluminal Galilean Genesis
Paolo Creminelli, Kurt Hinterbichler, Justin Khoury +2
We put forward an improved version of the Galilean Genesis model that addresses the problem of superluminality. We demote the full conformal group to Poincare symmetry plus dilatio…
Spectral Networks and Snakes
Davide Gaiotto, Gregory W. Moore, Andrew Neitzke
We apply and illustrate the techniques of spectral networks in a large collection of A_{K-1} theories of class S, which we call "lifted A_1 theories." Our construction makes contac…
