Distinguishability in Random States, Eigenstates, and Gravity

Abstract: Recently, there has been significant progress in solving the black hole information problem from explicit calculations of the entropy of Hawking radiation, confirming consistency of gravity with unitarity. One aspect of the information problem left unresolved by entropy calculations is the distinguishability of different black hole microstates: why do different microstates appear to lead to the same final (thermal) state? I will address this problem by studying the distinguishability of radiation coming from different black holes. In parallel, I will present a derivation of the subsystem eigenstate thermalization hypothesis for a class of chaotic many-body systems as well as generalizations to tensor network states.

Frontiers of Holographic Duality-3

Series comments: Having been initially used as a tool to explore strongly coupled phenomena, holography found important applications and intriguing insights in the structure of quantum gravity and quantum information, linking them to certain universal properties of strongly coupled chaotic quantum systems. It provides unified geometric tools for the description of various phenomena in the heavy ions collision physics, many-body physics applications, black hole physics, and quantum information theory.

The aim is to explore a wide variety of aspects of holographic duality, bringing together specialists in main topics to have comprehensive, but intensive discussions of the frontiers of holography and closely related subjects of quantum information and strongly-coupled theory.

The topics to be discussed include holographic duality and applications:

-holographic quantum chromodynamics and heavy ions collisions; -entanglement, chaos and many-body phenomena; -black holes and quantum information.
