We propose a first-principles theoretical approach for the description of aging linear viscoelastic properties colloidal liquid after sudden quench into dynamically arrested (glass or gel) state. Specifically, we couple general expression time-evolving shear-stress relaxation function G(τ;t), written in terms non-equilibrium structure factor S(k;t) and intermediate scattering F(k,τ;t), with equations that determine provided by self-consistent generalized Langevin equation theory. In this...
Relevant and fundamental concepts of the statistical mechanical theory classical liquids are ordinarily introduced in context description thermodynamic equilibrium states. This makes explicit reference to probability distribution functions \emph{equilibrium} ensembles (canonical, microcanonical, ...) derivation general relations between inter-particle interactions measurable macroscopic properties a given system. includes, for instance, expressing internal energy pressure as functionals...
We propose a first-principles theoretical approach for the description of aging linear viscoelastic properties colloidal liquid after sudden quench into dynamically arrested (glass or gel) state. Specifically, we couple general expression time-evolving shear-stress relaxation function $\eta(\tau;t)$ (whose $\tau$-integral is instantaneous viscosity $\eta(t)$), written in terms non-equilibrium structure factor $S(k;t)$ and intermediate scattering $F(k,\tau;t)$, with equations that determine...
We report a novel approach based on the non-equilibrium self-consistent generalized Langevin equation (NESCGLE) theory that allows for first principles prediction of zero-shear viscosity in glass- and- gel-forming materials. This new modulus NESCGLE facilitates theoretical description and interpretation experimental data concerning out-of-equilibrium rheological properties viscous liquids during their amorphous solidification. The predictive capability our is illustrated here by means...
