Precursors and BRST Symmetry
Jan de Boer, Ben Freivogel, Laurens Kabir +1
In the AdS/CFT correspondence, bulk information appears to be encoded in the CFT in a redundant way. A local bulk field corresponds to many different non-local CFT operators (precu…
Sub-AdS Scale Locality in AdS/CFT
Alexandre Belin, Ben Freivogel, Robert A. Jefferson +1
We investigate sub-AdS scale locality in a weakly coupled toy model of the AdS/CFT correspondence. We find that this simple model has the correct density of states at low a…
Precursors, Gauge Invariance, and Quantum Error Correction in AdS/CFT
Ben Freivogel, Robert A. Jefferson, Laurens Kabir
A puzzling aspect of the AdS/CFT correspondence is that a single bulk operator can be mapped to multiple different boundary operators, or precursors. By improving upon a recent mod…
Vacua and correlators in hyperbolic de Sitter space
Fotios V. Dimitrakopoulos, Laurens Kabir, Benjamin Mosk +2
We study the power - and bi -spectrum of vacuum fluctuations in a hyperbolic section of de Sitter space, comparing two states of physical interest: the Bunch-Davies and hyperbolic…
Casting Shadows on Holographic Reconstruction
Ben Freivogel, Robert Alan Jefferson, Laurens Kabir +2
In the context of the AdS/CFT correspondence, we study several holographic probes that relate information about the bulk spacetime to CFT data. The best-known example is the relati…
Geometry of the Infalling Causal Patch
Ben Freivogel, Robert A. Jefferson, Laurens Kabir +1
The firewall paradox states that an observer falling into an old black hole must see a violation of unitarity, locality, or the equivalence principle. Motivated by this remarkable…
