The analytical solution of the Ornstein± Zernike equation in the mean-spherical approximation for a Yukawa ̄ uid and adhesive hard sphere Yukawa ̄ uid with factorizable coe cients is used to derive a simple form for the thermodynamic properties for both mixtures. The second system contains an additional interaction. However, the general thermodynamic expressions were obtained in similar form for...

A second-order Taylor series expansion of the free energy functional provides analytical expressions for the magnetic field dependence of the free energy and of the magnetization of ferrofluids, here modeled by dipolar Yukawa interaction potentials. The corresponding hard core dipolar Yukawa reference fluid is studied within the framework of the mean spherical approximation. Our findings for th...

We investigate the liquid-vapor interface of the restricted primitive model for an ionic fluid using a density functional approach. The applied theory includes the electrostatic contribution to the free energy functional arising from the bulk energy equation of state and the mean spherical approximation for a restricted primitive model, as well as the associative contribution, due to the format...

A light-front treatment for spherical nuclei is developed from a relativistic effective Lagrangian and employing the mean field approximation. Minimizing the nuclear minus momentum subject to the constraint that, in the rest frame, the expectation values of the plusand minus-momenta are the same leads to a formalism in which rotational invariance is recovered. Light cone variables have long bee...
