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, 7 February 2019 at 14:00 in the library reading room “Dr. Dragan Popović" of the Institute of Physics Belgrade. The talk entitled
Bound on chaos, black holes and the entropy problem
will be given by Dr. Mihailo Čubrović (Scientific Computing Laboratory, Center for the Study of Complex Systems, Institute of Physics Belgrade). Abstract of the talk:
We will discuss the mechanisms of chaos and thermalization in Einstein gravity by looking at dynamics of strings in black hole geometries. The black hole horizon imprints to the scattering string the maximum possible Lyapunov exponent, proportional to the temperature and the spin of the string. This generalized bound on chaos can be realized also in absence of gravity, in strongly degenerate systems such as glasses. Finally, we will discuss the relation of the chaos bound to the stability of the wormhole geometries proposed recently as a solution of the black hole entropy loss problem.
Best regards,
Antun Balaž
