Dear Colleagues, 

There will be a seminar by Onur Gun on Friday December 25 14:00 organized by 
the Istanbul Center for Mathematical Sciences at Bogazici University. The 
seminar will be held at the center  (south campus, when entering from Etiler 
gate, make a sharp turn to the right just before reaching the main 
quadrangle and follow the path further down, passing the Mithat Alam Film 
Center). 
Details are as below. All interested are invited. 

Speaker: Onur Gun,
LATP, Universite de Provence-Aix Marseille I

Title: Universality of transient dynamics and aging for spin glasses

Abstract: We consider Random Hopping Time (RHT) dynamics of mean field spin 
glass models. We explain the RHT dynamics in the context of trap models. 
Next, we study the dynamics of the Random Energy Model (REM) and prove that 
under a proper normalization the clock process of the dynamics converges to 
an extremal process and the system exhibits aging like behavior. Finally, we 
prove that the same is true for Sherrington - Kirkpatrick (SK) model and p-
spin models. This confirms Bouchaud's REM-like trap model as a universal 
aging mechanism for these systems.
