Propagation gap for shear waves in binary liquids: Analytical and simulation study
arXiv:2312.10721
Abstract
Transverse collective excitations in a binary liquid mixture are studied for different mass ratio of components at fixed numerical density. Increasing the mass ratio results in a larger gap width for shear waves. A four-variable dynamic model of transverse dynamics in binary liquids is solved analytically with an account of cross-correlations between total mass and mass-concentration current fluctuations. An equation for the propagation gap of shear waves for binary liquids is reported and analyzed.
