Quantum Aspects of Black Holes - Lecture 3
International Centre for Theoretical Sciences via YouTube
Overview
Syllabus
Start
Traversable wormholes
Given that we have coupled the two sides,
Quantum teleportation
Quantum gravity in the lab
Application to the Hayden Preskill problem
Old black hole
Bob's black Hole, which is Part of
Making the wormhole traversable
Bob now gets the message at
More like the HP figure
There are never two copies of the message.
One other variant of the same basic traversable wormhole idea
First a comment
Making the TFD
Meeting behind the horizon
End of lecture 2
We expect that these energy levels to be like those of a chaotic system.
A simpler observable
The SYK model
Consider a theory with random couplings
The ramp
We will now discuss some results for random matrices.
Results for Random Matrices
Ramp from gravity
It turns out that there is no gravity solution for
Constraining the energy
Then we expect that is conjugate to By in the region,
Quantum fields in this background
Success! We have found the gravity solution for the ramp!
Gravity lets us compute the statistical properties of the noise.
Connection with replica wormholes
