The collective dynamics in liquid water is an active research topic experimentally, theoretically and via simulations. Here, ab initio molecular dynamics simulations are reported in heavy and ordinary water at temperature ...

A simple ansatz for the study of velocity autocorrelation functions in fluids at different timescales is proposed. The ansatz is based on an effective summation of the infinite continued fraction at a reasonable ...

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 ...

Contributions of different collective excitations to the density-density and heat-heat time correlation functions in pure liquids are studied within an approach of generalized collective modes. It is shown, that a kinetic ...

Longitudinal collective dynamics of an equimolar Lennard-Jones KrAr mixture is studied in detail in a wide range of spatial and time scales. Combining both the molecular dynamics simulations and analytical generalized ...

Longitudinal as well as transverse dynamics of a molten salt beyond the hydrodynamic region is studied within the generalized collective modes (GCM) approach. An analytical three-variable model is applied to the treatment of ...

It is our great pleasure to present a Special issue of Condensed Matter Physics in honour of the renowned scientist and our former scientific advisor Professor A.D.J. "Tony" Haymet, who turned 60 this February. An ...
