The derivation of the quasiclassical equations considered here depends on the structure of the Gor'kov equations. In a spatially varying situation they couple particle and hole functions with momenta only very near the Fermi surface. The equations ar

When a wire resonator is moving in superfluid3He-B at low temperature, there is a drag force due to scattering of thermally excited quasiparticles. The form of the graph of the drag force against the wire velocity depends strongly on the type of scat

We present a microscopic model of the scattering of quasiparticles in superfluid3He-B by a moving solid surface. This is used to calculate the thermal damping of a wire resonator in the low temperature regime. The calculated damping force is in good

When a microscopic object moves through superfluid {sup 3}He, it experiences a force arising from the effect of quasiparticle scattering. The authors develop a three-dimensional microscopic model to calculate the force on a smooth cylinder moving at

Transport coefficients in the mixed state have simple expressions when the response is local. For dirty materials the ultrasonic attenuation is given by the local expression over the whole mixed-state regime because of the Coulomb interaction between

We present a general formalism for the calculation of electronic transport properties in inhomogeneous superconducting alloys, neglecting fluctuations of the self-consistent potentials. All previously known results can easily be rederived as limiting

A recent dirty-limit version of the Gor'kov theory is used to calculate numerically the self-consistent structure and free energy of isolated vortices and of the vortex lattice in the circular cell approximation at arbitrary temperature and Ginzburg-

A simple generalized time-dependent Ginzburg-Landau equation valid for dirty superconductors in the vicinity of ${T}_{c}$ is derived. For thin homogeneous filaments it exhibits oscillatory phase-slip solutions below and above the critical depairing c

Measurements by Pippardet al. have shown the existence of an extra resistance due to the penetration of an electrical potential into a superconductor. Previous theories of this effect are unable to explain the full temperature dependence of the extra
