Zdravo svima,
najavljujem da će u petak, 23. februara, Mihailo Čubrović (Institut za
fiziku, Zemun) održati seminar na Institutu za fiziku.

Naslov: Chaos and factorization beyond classical horizons
Apstrakt: Chaotic dynamics of black holes has proven to be of vital
importance for the understanding of the black hole information problem.
Within the replica formalism, a related issue is that of
nonfactorization of partition functions of wormhole geometries. We
consider these questions deep in the stringy regime, described by the
BFSS and IKKT matrix models, where the notions of geometry and horizon
do not apply anymore. Generic solutions factorize when averaged over the
quantum fluctuations, whereas the chaotic properties are non-universal.
We argue that the correct notion that characterizes the black hole
scrambling is instead that of quantum magic (stabilizer Renyi entropy),
which guarantees that the dynamics is complex enough to accommodate the
total information on infalling matter.
