Gibbs free energy and Helmholtz free energy for a three-dimensional Ising-like model [PDF]
Condensed Matter Physics, 2011 The critical behavior of a 3D Ising-like system is studied at the microscopic level of consideration. The free energy of ordering is calculated analytically as an explicit function of temperature, an external field and the initial parameters of the model.

Bound state densities and the Helmholtz free energy [PDF]
EPJ Web of Conferences, 2012 Bohr's conception of the compound nucleus is based on the idea of ‘longlived’ nuclear states in which all single particles are bound. We briefly discuss the properties of the density of bound states and then use two prescriptions, that of Brack and ...

Temperature dependence of the Helmholtz free energy of liquid alkali metals
Bibechana, 2012 The Gibbs-Bogoliubov variational method has been considered to study the Helmholtz free energy of liquid alkali metals (Na, K, Rb and Cs) as a function of temperature, using Heine Abarenkov type model potential with Hubbard-Sham exchange and correlation

The ion equation of state of plasmas in the warm dense matter regime
AIP Advances, 2023 The existing “quotidian equation of state (QEOS)” model [More et al., Phys. Fluids 31, 3059 (1988)] has been revised, and an alternative set of formulas is provided for the Helmholtz free energy, internal energy, heat capacity, and pressure.

AIP Advances, 2022 We examined the accuracy of the reference interaction site model theory in terms of the thermodynamics of fluids consisting of single-component diatomic molecules, where we evaluated the internal energy, pressure, and isothermal compressibility.

Fast multiple-fluid simulation using Helmholtz free energy [PDF]
ACM Transactions on Graphics, 2015 Multiple-fluid interaction is an interesting and common visual phenomenon we often observe. In this paper, we present an energy-based Lagrangian method that expands the capability of existing multiple-fluid methods to handle various phenomena, such as extraction, partial dissolution, etc.

Impact of Thermal Fluctuations on Logarithmic Corrected Massive Gravity Charged Black Hole
Entropy, 2021 We investigate the influence of the first-order correction of entropy caused by thermal quantum fluctuations on the thermodynamics of a logarithmic corrected charged black hole in massive gravity.

Counter-intuitive penetration of droplets into hydrophobic gaps in theory and experiment
Scientific Reports, 2023 Droplets that spontaneously penetrate a gap between two hydrophobic surfaces without any external stimulus seems counterintuitive. However, in this work we show that it can be energetically favorable for a droplet to penetrate a gap formed by two ...

Investigation of some basic thermodynamic properties of Na-K alloy
Bibechana, 2021 Investigation of thermodynamic of liquid binary alloys using pseudopotential theory is reported. The potential suggested by Fiolhais et al. with its individual parameters is used for the entire calculation.

Free Energy Changes during Spherical Droplet Deposition—Mechanistic Model
Energies, 2022 On the basis of theoretical considerations (mechanistic model), an equation was determined that allowed to calculate the free energy (Helmholtz) of a spherical droplet deposited on a flat surface in a system without external forces.
