Wanted: a mathematical home for our out-of-equilibrium world. Can Wigner's friend and holography cure Boltzmann's Brain?
Many otherwise plausible cosmologies suffer from a Boltzmann brain problem, with spurious local recurrences swamping "correct" global ones. What properties can help physical models avoid this problem? A resolution may involve understanding the emergence and perspective of "Wigner's friends"---subsystems with possibly evanescent classical experiences---within a larger unitarily evolving quantum system, as well the interplay between gravity and locality on which the global/local distinction depends.
Registration
Participation is open, but speakers are by invitation only. If you register for the workshop please note that due to space limitations you have not been accepted before you have received confirmation from NBIA Administrative Officer Jane Elvekjaer.
The meeting will take place in the historical Auditorium A of the Niels Bohr Institute.
We start on Tuesday, 29th of October, at 9.50 am. A more detailed schedule can be found in the Programme section.
