Query: Thermally activated flow in models of amorphous solids   Amorphous solids yield at a critical value $\Sigma_c$ of the imposed stress
$\Sigma$ through a dynamical phase transition. While sharp in athermal systems,
the presence of thermal fluctuations leads to the rounding of the transition
and thermally activated flow even below $\Sigma_c$. Here, we study the steady
state thermal flow of amorphous solids using a mesoscopic elasto-plastic model.
In the Hebraud-Lequex (HL) model we provide an analytical solution of the
thermally activated flow at low temperature. We then propose a general scaling
law that also describes the transition rounding. Finally, we find that the
scaling law holds in numerical simulations of the HL model, a 2D elasto-plastic
model, and in previously published molecular dynamics simulations of 2D
Lennard-Jones glass.
