The classical equation of state of fully ionized plasmas

open access: yesAIP Advances, 2011
The aim of this paper is to calculate the analytical form of the equation of state until the third virial coefficient of a classical system interacting via an effective potential of fully Ionized Plasmas. The excess osmotic pressure is represented in the

Predicting The Onset of Asphaltene Precipitation by Virial EOS [PDF]

open access: yes, 2008
In this study, the Onset of Asphaltene Precipitation is predicted by a modified Virial equation of state. The bases of quantum mechanics and statistical thermodynamics are used to evaluate the potential energy and intermolecular forces related to ...

Can an Ab Initio Three-Body Virial Equation Describe the Mercury Gas Phase?

open access: yes, 2016
We report a sixth-order ab initio virial equation of state (EOS) for mercury. The virial coefficients were determined in the temperature range from 500 to 7750 K using a three-body approximation to the N-body interaction potential.

The virial theorem and the Price equation [PDF]

open access: yes
We observe that the time averaged continuous Price equation is identical to the positive momentum virial theorem, and we discuss the applications and implications of this connection.13 ...

Can an ab initio three-body virial equation describe the mercury gas phase?

open access: yes, 2014
We report a sixth-order ab initio virial equation of state (EOS) for mercury. The virial coefficients were determined in the temperature range from 500 to 7750 K using a three-body approximation to the N-body interaction potential.

Generalised virial theorems in classical and quantum physics [PDF]

open access: yes, 2014
Generalisations of the virial theorm in Classical Mechanics and Quantum Mechanics are examined. It is shown that the generalised virial theorem in Quantum Mechanics leads to certain relations between matrix elements.

Nuclear and hadron matter equation of state within the induced surface tension approach

open access: yesEPJ Web of Conferences, 2017
We present a novel equation of state which is based on the virial expansion for the multicomponent mixtures with hard core repulsion. The suggested equation of state explicitly contains the surface tension which is induced by particle interaction.

Improved first-principles calculation of the third virial coefficient of helium

open access: yes, 2011
We employ state-of-the-art pair and three-body potentials with path-integral Monte Carlo (PIMC) methods to calculate the third density virial coefficient C(T ) for helium.

Effects of Induced Surface Tension in Nuclear and Hadron Matter

open access: yesEPJ Web of Conferences, 2017
Short range particle repulsion is rather important property of the hadronic and nuclear matter equations of state. We present a novel equation of state which is based on the virial expansion for the multicomponent mixtures with hard-core repulsion.

Self-consistent approximation and fifth virial coefficients

open access: yes, 1972
The self-consistent approximation of Rushbrooke and Hutchinson is extended so as to give consistent virial coefficients to any order by expanding the parameter Φ in terms of density, namely φ(p.T) :∗sum∞l-4; φi(T)pl-4 By using ...
