“…We also found out that if better accuracy is required, the data for the excess thermal energy can be fitted by the following slightly modified expression 15) is clearly more accurate and can be used in the regime of weaker coupling, compared to the simple form (13). However, it is also less practical in evaluating thermodynamic parameters other than the excess internal energy.…”

“…Various aspects of structural, dynamical, and thermodynamical properties of Yukawa systems were studied numerically, some representative examples can be found in Refs. [7][8][9][10][11][12][13][14][15][16]. Results of these studies found wide applications, for instance, to explain phase transitions in complex (dusty) plasmas, [17][18][19][20][21] and in colloidal systems.…”

“…Thermodynamic properties of 2D Yukawa systems have been of considerable continuous interest in the last couple of decades, largely in the context of complex plasmas. 12,13,[54][55][56][57][58] However, to the best of our knowledge, no comprehensive results across coupling regimes along with simple and reliable approximations convenient for practical use have been proposed. In the present paper, we study systematically thermodynamics of 2D Yukawa systems in a very broad parameter regime, from very weakly interacting gaseous state to strongly interacting fluid and solid states.…”

Thermodynamics of two-dimensional Yukawa (screened Coulomb or Debye-Hückel) systems is studied systematically using molecular dynamics (MD) simulations. Simulations cover very broad parameter range spanning from weakly coupled gaseous states to strongly coupled fluid and crystalline states. Important thermodynamic quantities, such as internal energy and pressure, are obtained and accurate physically motivated fits are proposed. This allows us to put forward simple practical expressions to describe thermodynamic properties of two-dimensional Yukawa systems. For crystals, in addition to numerical simulations, the recently developed shortest-graph interpolation method is applied to describe pair correlations and hence thermodynamic properties. It is shown that the finite-temperature effects can be accounted for by using simple correction of peaks in the pair correlation function. The corresponding correction coefficients are evaluated using MD simulation. The relevance of the obtained results in the context of colloidal systems, complex (dusty) plasmas, and ions absorbed to interfaces in electrolytes is pointed out.

“…Hartmann et al 12 calculated the pressure from the pair correlation function. Vaulina et al 36,37 got an expression of pressure using a semi-empirical jumps theory. In a recent paper, 1 the pressure is calculated as exact values from the shear stress tensor obtained from moleculardynamical (MD) simulations of 11 isochores for 2D Yukawa liquids, i.e., simulations of 2D liquid dusty plasmas, as briefly reviewed in Sec.…”

Recently, the pressure of two-dimensional (2D) Yukawa liquids has been calculated from the simulations of isochores [Feng et al., J. Phys. D: Appl. Phys. 49, 235203 (2016)], which is applicable to 2D dusty plasmas. Thus, the equation of state for 2D strongly coupled liquid dusty plasmas is obtained. Isobars and isotherms of 2D liquid dusty plasmas are derived from this equation of state. For 2D liquid dusty plasmas, the surface corresponding to this equation of state has also been obtained in the 3D space of the pressure, the temperature, and the screening parameter which is related to the volume in the equilibrium state.

“…In the case of our interaction potential, physical properties of the system, such as pressure P , are fully determined by the pair correlation function. Most investigations related to the thermodynamic properties consider Yukawa systems and use different numerical methods [5][6][7].…”

In this paper weakly and strongly non-ideal plasmas are considered. In both cases the equations of state for hydrogen and dusty plasmas were studied on the basis of effective potentials. In the first case the thermodynamic properties for hydrogen plasmas were studied by the method of effective potentials taking into account quantummechanical diffraction, symmetry and screening effects. For strongly non-ideal plasma or dusty plasma the equations of state were considered using radial distribution functions and effective interaction potential, which describes interactions of charged dust grains with dipole moments.
