We study thermal fluctuations in a conducting medium which may be spatially non-uniform and anisotropic. The fluctuation spectra for charge and current density, and for the electromagnetic fields, are expressed in terms of the basic propagators of the macroscopic equations. The theory is based...

We consider a rigid body of arbitrary shape with a permanent charge distribution and a permanent dielectric profile immersed in a fluid with a frequency dependent dielectric constant. The body performs small oscillatory translational and rotational motions and the whole system is subjected to an...

We study the propagation of scalar waves in a disordered array of static scatters. We derive a cluster expansion for the optical potential in analogy to that for the dielectric constant of a polarizable suspension. It is shown that the long range of the free space Green function leads to...

The theory of average local velocity fields developed in the preceding article is applied to a suspension of spherically symmetric polymers. Three transport properties of the suspension are analyzed, namely the concentration dependence of the translational and rotational friction coefficient of...

We discuss fluctuation theorems for dielectrics from a unified point of view. A simple susceptibility theorem is proven for a uniform dielectric contained in a vessel with ideally conducting walls of arbitrary shape. Also we derive a theorem for systems with periodic boundary conditions. The...

We study the effective dielectric constant of a two-phase composite for the case where the dielectric constants of the two components are complex. Milton has derived a sequence of narrowing bounds in the complex plane limiting the possible values of the effective dielectric constant, assuming...

The normal mode analysis of systems of linear macroscopic equations in irreversible thermodynamics is extended in several ways. When the characteristics equation has multiple roots, there may appear normal solutions that do not decay purely exponentially, but a closed form for the Green function...

We present a general scheme to deal with situations in the thermodynamics of irreversible processes in which some of the variables vary on a much faster time-scale than others. The theory is based on a transformation of variables of a type first introduced into thermodynamic fluctuation theory...

A systematic study is made of the average local velocity field acting at a selected particle in a fluid suspension. The flow disturbance due to a single particle is analyzed in terms of force multipoles. The theory is developed in close analogy to that for the corresponding problem of the local...

In the framework of our generalization of the Debye-Bueche theory for the frictional properties of dilute polymer solutions we study the intrinsic viscosity. A careful definition of the intrinsic viscosity for polymers with spherically symmetric density distribution is given. The equations are...
