- 2 Making traversable wormholes Understanding global Ads2
- 3 AdS2 : A traversable wormhole
- 4 AdS2 - thermal Rindler coordinates
- 5 AdS2 vs NAdS2 asymptotic boundary conditions
- 6 First recall some facts about nearly AdS, boundary conditions...
- 7 Nearly AdS2 gravity
- 8 Gravitational dynamics
- 9 We will look at a simple example
- 10 In parallel we will look at a similar problem in the SYK model.
- 11 Sachdev, Ye, Kitaev model SYK
- 12 Two copies of SYK + Interaction
- 13 is a solution of the equations of motion
- 14 Nearly AdS2
- 15 Spectrum reflects the conformal symmetry
- 16 It is a bit like the Zeeman effect in atomic physics where an atom with non-zero spin,
- 17 In SYK we can also solve the theory beyond the low energy limit.
- 18 SYK analysis
- 19 For usual SYK
- 20 Simplest ansatz
- 21 Finite temperature SYK case, large
