Slow dynamics of a confined supercooled binary mixture: direct space analysis.
Dynamical properties of a Lennard-Jones binary mixture embedded in an off-lattice matrix of soft spheres are studied in the direct space upon supercooling by molecular dynamics simulations. On lowering the temperature, the smaller particles tend to avoid the soft sphere interfaces and correspondingly their mobility decreases below one of the larger particles. The system displays a dynamic behav...
متن کاملSlow dynamics of supercooled water confined in nanoporous silica materials
We review our incoherent quasielastic neutron scattering (QENS) studies of the dynamics of supercooled water confined in nanoporous silica materials. QENS data were analysed by using the relaxing cage model (RCM) previously developed by us. We first use molecular dynamics (MD) simulation of the extended simple point charge model (SPC/E) for bulk supercooled water to establish the validity of th...
متن کاملa-relaxation in a supercooled binary mixture
The a-master functions of the mode coupling theory for a binary soft-sphere mixture are presented. They are directly determined by the static structure factors S,. The asymmetric stretching of the susceptibility spectra, which is mainly caused by the common von Schweidler high frequency asymptote, is well described by Kohlrausch fits. The stretching parameters and a-relaxation times for various...
متن کاملCritical Fluctuations of a Confined Binary Mixture
Exploiting the mapping between a binary mixture and the Ising model we have analyzed the critical fluctuations by means of the density-matrix renormalization group technique. The calculations have been carried out for a two-dimensional Ising strip subject to equally strong surface fields. It was found that the critical Casimir force has significantly different behavior on opposite sides of the ...
