Abstract:
A closed interpolation equation is derived based on exact relations of quantum statistical theory for Coulomb systems and the Born–Oppenheimer approximation. This equation relates pressure and its derivative to density at a fixed temperature for a simple quasi-classical liquid, in which the effective pair potential of particle–particle interaction has a Fourier transform.
