Thermal Jamming of a Colloidal Glass
Abstract
We investigate the effect of temperature on structure and dynamics of a colloidal glass created by
tethering polymers to the surface of inorganic nanoparticles. Contrary to the conventional assumption, an
increase in temperature slows down glassy dynamics of the material, yet causes no change in its static
structure factor.We show that these findings can be explained within the soft glassy rheology framework if
the noise temperature X of the glass phase is correlated with thermodynamic temperature.
