We formulate the solution of the linear Navier-Strokes equations for time-dependent incompresible flow about a spherical particle in terms of a scattering formalism. The solution is written as an expansion in terms of incident and scattered waves. The amplitudes of the outgoing waves are related...

We evaluate the complete diffusion matrix describing the translation and rotation of two spherically symmetric polymers in hydrodynamic interaction in a viscous fluid. Explicit results in terms of a series expansion in inverse powers of the distance l between centers is obtained by a method of...

We study the self-energy of a scalar wave propagating in a disordered static array of spherical scatterers. We employ the cluster expansion developed in a preceding article and provide detailed expressions for many contributions to the self-energy. The two-body term is covered completely. The...

We study the rate of diffusion-controlled reactions in a random array of stationary spherical sinks. We simplify the system to a monopole model and show that different theories proposed in the literature lead to different results for the first few terms in the density expansion of the rate...

We apply Kac's method of functional integration to a spatially non-uniform fluid with short and long-range interactions. The system with short-range interactions is treated as a reference system to which the long-range pair interaction is added as a perturbation. All equilibrium distribution...

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...
