Query: Rheological properties vs Local Dynamics in model disordered materials
  at Low Temperature   We study the rheological response at low temperature of a sheared model
disordered material as a function of the bond rigidity. We find that the flow
curves follow a Herschel-Bulkley law, whatever is the bond rigidity, with an
exponent close to 0.5. Interestingly, the apparent viscosity can be related to
a single relevant time scale $t_{rel}$, suggesting a strong connection between
the local dynamics and the global mechanical behaviour. We propose a model
based on the competition between the nucleation and the avalanche-like
propagation of spatial strain heterogeneities. This model can explain the
Herschel-Bulkley exponent on the basis of the size dependence of the
heterogeneities on the shear rate.
