Variational approach to Yukawa fluids. II. Instantaneous elastic moduli and sound velocities
S. A. Khrapak, A. G. Khrapak
The variational approach based on the Bogoliubov inequality using the fluid of hard spheres as a reference system is implemented to evaluate instantaneous shear, bulk and longitudi…
Variational approach to Yukawa fluids. I. Thermodynamics
S. A. Khrapak, A. G. Khrapak
The excess energy, entropy, and pressure of a strongly coupled Yukawa fluid are calculated from the variational approach using the fluid of hard spheres as a reference system. As i…
Vibrational model of entropy in dense two-dimensional fluids
Sergey Khrapak
A vibrational paradigm of atomic dynamic in dense fluids is known to provide useful insight on the transport and thermodynamic properties of fluids in three dimensions. In this pap…
Excess entropy scaling of the transverse sound speed in simple fluids
Sergey Khrapak
A calculation of the transverse sound velocity as a function of excess entropy is presented for several simple fluids, including the Lennard-Jones, Yukawa, one-component plasma, in…
