Gravity, Quantum Fields and Information
This talk is a discussion session led by Lampros Lamprou (Massachusetts Institute of Technology) and is based on the talk: [https://www.youtube.com/watch?v=v02H8cPH1G8], whose title and abstract are the following: Inside the Hologram: The Bulk Observer’s Experience – Lampros Lamprou.
“I will present a holographic framework for reconstructing the experience of bulk observers in AdS/CFT. In particular, I will show how to recover the proper time and energy distribution measured along bulk worldlines, directly in the CFT via a universal, background-independent prescription. For an observer falling into an eternal AdS black hole, the proposal resolves a conceptual puzzle raised by Marolf and Wall. It suffers, however, from the “frozen vacuum” problem for which I will offer some preliminary comments. Notably, the approach does not depend crucially on the asymptotic Hamiltonian and it outlines a general framework for the emergence of time.”
The Quantum Gravity and Information seminar series is a joint initiative between the Max Planck Institute for Gravitational Physics (Potsdam), the University of Amsterdam and University College London.
