Course Description

Overview

Explore a 42-minute conference talk from the Workshop on Qubits and Spacetime, delivered by Raphael Bousso at the Institute for Advanced Study. Delve into the complex topic of "Black Hole Coarse Graining, Connes-Cocycle Flow, and Its Bulk Dual." Examine key concepts such as entanglement wedge complementarity, ensemble interpretation, and information loss in black holes. Investigate the cost of unitarity, classical and quantum black hole coarse-graining, and the Ant Conjecture. Learn about the vacuum modular Hamiltonian and the bulk dual of Connes Cocycle Flow. Gain insights into the quantitative testing of these theories and their implications for our understanding of black holes and spacetime.

Syllabus

Intro
On Having Our Cake and Eating It
Entanglement Wedge Complementarity is Valid
Ensemble Interpretation
Ensemble = Information Loss On the boundary, each member of the ensemble produces a different out-state from the same in-state. → Ensemble average of the out-state = mixed.
The Cost of Unitarity
Classical Black Hole Coarse-Graining
Part 11
Quantum Black Hole Coarse-Graining
Shock at the Cut
Ant Conjecture as a Prediction
Proof of the Ant Conjecture
Vacuum Modular Hamiltonian
Bulk Dual of Connes Cocycle Flow
