Quasi-universal behaviour of shear relaxation times in simple fluids
S. A. Khrapak, A. G. Khrapak
We calculate the shear relaxation times in four important simple monatomic model fluids: Lennard-Jones, Yukawa, soft-sphere and hard-sphere fluids. It is observed that in properly…
Excess entropy of strongly coupled Yukawa fluids
Sergey Khrapak
The entropy of strongly coupled Yukawa fluids is discussed from several perspectives. First, it is demonstrated that a vibrational paradigm of atomic dynamics in dense fluids can b…
Elementary vibrational model for transport properties of dense fluids
Sergey Khrapak
A vibrational model of transport properties of dense fluids assumes that solid-like oscillations of atoms around their temporary equilibrium positions dominate the dynamical pictur…
Excess entropy determines the applicability of Stokes-Einstein relation in simple fluids
Sergey Khrapak, Alexey Khrapak
The Stokes-Einstein (SE) relation between the self-diffusion and shear viscosity coefficients operates in sufficiently dense liquids not too far from the liquid-solid phase transit…
Note: Sound velocities of generalized Lennard-Jones () fluids near freezing
Sergey Khrapak
In a recent paper [S. Khrapak, Molecules {\bf 25}, 3498 (2000)] the longitudinal and transverse sound velocities of conventional Lennard-Jones systems at the liquid-solid coexisten…
When do soft spheres become hard spheres?
S. A. Khrapak, N. P. Kryuchkov, L. A. Mistryukova +1
The conventional (Zwanzig-Mountain) expressions for instantaneous elastic moduli of simple fluids predict their divergence as the limit of hard sphere (HS) interaction is approache…
