On the basis of the Maxwell equations for the continuously varying electromagnetic fields, describing a system with an interfacial layer between two bulk phases, interfacial electromagnetic fields, charge density and currents are defined at the dividing surface. It is shown that the behaviour of...

The problem of the compatibility of the results obtained from approximate expressions for the junior distribution functions is viewed under a broad aspect. This paper concerns the compatibility of the calculated values of not only the energy and pressure but also of the higher-order derivatives...

The forward scattering of radiation by multicomponent systems is expressed in terms of the chemical potentials and of the collision lengths associated with the components.

How ordinarily existing scatters determine electric resistivity in a superconducting state is calculated here in order to explain why the electric resistance vanishes suddenly at the critical temperature Tc of a superconductor. Three mechanisms are considered: (1) non-magnetic impurity...

We study the statistical mechanics of a many-boson system with constant two-body potential energy g/N (g 0, N is the number of bosons). The grand canonical partition function can be computed exactly by functional integration which allows for a simple discussion of spontaneous symmetry...

A microscopic description of self-diffusion in a moderately dense classical one-component plasma is given on the basis of renormalized kinetic theory. The effects of close binary collisions and of collective interactions in the plasma are taken into account through the use of a composite memory...

The classical mechanics of nonrelativistic particles is generalized by also considering the spin components as canonical variables. Poisson-brackets and canonical transformations are discussed. The Lagrangian equations of motion are given and it is shown how rotational invariance leads to well...

Dielectric constants for the Stockmayer fluid are computed both from the equilibrium fluctuations of the polarization and from the polarization response to an applied field in a molecular dynamics simulation with periodic boundary conditions and with the dipole interactions treated by the Ewald...

A general theory of rate processes is developed. Starting from the first principles, the non-Markovian and Markovian type equations governing relaxation processes are derived. Under certain conditions (which are specified) these equations may be approximately reduced to master equations.

The use of absolute rate theory is suggested for a simple description of the dynamics of thermally generated solitons in the underdamped regime. Rate theory is reformulated to describe thermal transitions between continuous states of nonlinear wave equations emphasizing the soliton or...
