Inside the Horizon with AdS/CFT
Per Kraus, Hirosi Ooguri, Stephen Shenker
Using the eternal BTZ black hole as a concrete example, we show how spacelike singularities and horizons can be described in terms of AdS/CFT amplitudes. Our approach is based on a…
Initial Conditions for Inflation
Nemanja Kaloper, Matthew Kleban, Albion Lawrence +2
Free scalar fields in de Sitter space have a one-parameter family of states invariant under the de Sitter group, including the standard thermal vacuum. We show that, except for the…
Signatures of Short Distance Physics in the Cosmic Microwave Background
Nemanja Kaloper, Matthew Kleban, Albion Lawrence +1
We systematically investigate the effect of short distance physics on the spectrum of temperature anistropies in the Cosmic Microwave Background produced during inflation. We prese…
