Expressions for the longitudinal and transverse current correlation functions of simple liquids are obtained using Mori's formalism. These involve unknown damping functions. The use of damping functions for a free gas gives results which are in complete disagreement with experiments. The results...

The modification of the damping rate of the sound modes by Coulomb phenomena is demonstrated from first principles. The heat modes of one- and two-component systems of charged particles are shown to differ by a factor cp/cv. Microscopic expressions for the interspecies energy and longitudinal...

A graphical approach is used to extend the response theory expression for nonequilibrium averages to any arbitrry order in deviations from equilibrium. Various ways in which the perturbation series about equilibrium can be resummed into gradient or Chapman-Enskog like expansions are presented....

Supergravity is shown to be the unique consistent interacting theory of massless spin-2 plus spin-3/2 particles. It is derived from the noninteracting form using the gauge invariances intrinsic to the latter. As a preliminary, the vierbein form of general relativity is also uniquely obtained...

A model due to Onsager and Temperley for the interface between thermodynamic phases in classical lattice gases is examined. It is found that a field is needed for stabilisation in two dimensions; in three dimensions, on the other hand, the interface is localised, unlike the drumhead model...

The equation of state for gases of point particles with logarithmic interaction is derived. The system exhibits a phase transition at a critical temperature Tc. The critical temperature is a function of the dimension of the system. A hard core must be added below Tc to prevent the system from...

A model for a two-dimensional lipid bilayer in which both short range repulsive forces and long range attractive forces play a role, and which can be solved exactly, is discussed. It is shown that the bilayer consists of long stretches of relatively densely packed lipids separated by small...

A relativistic method to calculate transport coefficients is developed for a binary mixture with arbitrary particle interaction. The heat conductivity, the diffusion coefficient, the thermal-diffusion coefficient, the shear viscosity and the volume viscosity are expressed in terms of...

The transport processes can be discussed either by kinetic equation method or by correlation function method. Using the former, linear transport equations are developed for the study of dynamic conductivity of a quantum imperfect gas employing a resolution of BBGKY hierarchy using Green...

We extend our previous kinetic theory of intercollisional interference effects to include vibrational perturbations in collisions, and so obtain expressions for the pressure shifts of the interference minima in H2-rare gas mixtures. These shifts are found to be different from those of the...
