Soft Glasses

Soft glasses produced after the cessation of shear flow exhibit persistent residual stresses. Mode coupling theory of the glass transition explains their history dependence in terms of nonequilibrium, nonlinear-response relaxation of density fluctuations.

Scattering Spectra

The physics and some predictions of recent mode coupling theories concerning the liquid to glass instability are reviewed with the scope to explore its potential to explain the dynamics of non-simple liquids. It is proposed that the dynamics scaling behaviour observed in the neutron scattering spectra of myoglobin reveal a critical temperature which is associated with the arrest of density fluctuations.

Brownian Dynamics Simulations

Brownian dynamics simulations of bidisperse hard discs moving in two dimensions in a given steady and homogeneous shear flow are presented close to and above the glass transition density. The stationary structure functions and stresses of shear-melted glass are compared quantitatively to parameter-free numerical calculations of monodisperse hard discs using mode coupling theory within the integration through transients framework. Theory qualitatively explains the properties of the yielding glass but quantitatively overestimates the shear-driven stresses and structural anisotropies.
