1-loop contribution to the dynamical exponents in spin glasses

We evaluate the corrections to the mean field values of the $x$ and the $z$ exponents at the first order in the $ε$-expansion, for $T=T_c $. We find that both $x$ and $z$ are decreasing when the space dimension decreases.

Fluctuations in a Spin Glass model with 1RSB

We discuss Gaussian fluctuations in a spin glass model with one replica symmetry breaking. We show how non-perturbative fluctuations of the break-point parameter can be included in the longitudinal propagator within linear response theory.
