Collective excitations in dynamics of liquids: a «toy» dynamical model for binary mixtures
We propose a new «toy» dynamical model that permits us to derive analytical expressions for dispersion
 of two branches of «bare» propagating collective excitations in binary disordered systems in the whole range
 of wavenumbers. These expressions are used for the analysis of depende...

| description | We propose a new «toy» dynamical model that permits us to derive analytical expressions for dispersion
of two branches of «bare» propagating collective excitations in binary disordered systems in the whole range
of wavenumbers. These expressions are used for the analysis of dependence of dispersion curves on mass ratio
and concentration at fixed density of the system. An effect of hybridization of two branches is discussed
in terms of mode contributions to time correlation functions. This allows us to estimate the regions with
dominant types of coherent or partial dynamics.
