<b>Universality of Transient Dynamics and Aging for Spin Glasses</b> <br>
<br>
<b>Abstract:</b> 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. <br>
