[institut] [phys4phys] SCL seminar: Mihailo Cubrovic, Thursday, 25 July, 14:00

[Antun Balaz]

Dear colleagues,

You are cordially invited to the SCL seminar of the Center for the Study of Complex Systems, which will be held on Thursday, 25 July 2024 at 14:00 in the library reading room “Dr. Dragan Popović" of the Institute of Physics Belgrade. The talk entitled

Weak chaos inside and outside of black holes

will be given by Dr. Mihailo Čubrović (SCL, Institute of Physics Belgrade). The abstract of the talk:

Black holes in general relativity are conjectured to be the most chaotic objects in nature due to their specific geometry and symmetries. In this talk we will explore how this picture changes in the presence of quantum and stringy corrections to classical gravity. More specifically, we will consider the dynamics of highly excited strings and matrix models and find that the resulting physics is drastically different from the classical gravity picture: even in the black hole regime the dynamics can be nonuniversal and weakly chaotic with regular structures, and the properties of the black hole state are encoded in these nonuniversal dynamical properties. We will discuss similar weak chaos in the Bose-Hubbard model as the prototypical low-energy quantum many-body system, but the consequences are very different in absence of the diffeomorphism invariance of gravity.


Best regards,
Antun Balaž
