Non-invertibility of Multiple-Scattered QELSS Spectra
George D. J. Phillies
We consider the spectrum S(q,t) and field correlation function f(q,t) of light quasielastically scattered from diffusing optical probes in complex viscoelastic fluids. Relationship…
Interpretation of Diffusing Wave Spectra in Nontrivial Systems
George D. J. Phillies
Mathematical methods previously used (Phillies, J. Chem. Phys., 122 224905 (2005)) to interpret quasielastic light scattering spectroscopy (QELSS) spectra are here applied to relat…
Viscosity of Suspensions of Hard and Soft Spheres
George D. J. Phillies
From a reanalysis of the published literature, the low-shear viscosity of suspensions of hard spheres is shown to have a dynamic crossover in its concentration dependence, from a s…
Diverging Static Length Scales and Clustering in Cold Lennard-Jones Fluids
Paul C. Whitford, George D. J. Phillies
We report molecular-dynamics simulations on a three-dimensional two-component Lennard-Jones fluid. We identify two distinct static length scales. The longer length scale, which div…
