Void Interaction

An exact solution for the induced field when a straight screw dislocation is adjacent to a spherical inhomogeneity is presented. This solution is used to calculate the interaction energy and force between the dislocation and the inhomogeneity. Specific results are given when the inhomogeneity is a spherical cavity (a void). The induced dilatation field is also obtained and used to discuss the resulting drift of interstitials into the void; the significance of this induced drift as a saturation mechanism in the growth of voids in irradiated materials is emphasized.

The Casimir-Polder and van der Waals interaction energy of an atom with infinitely thin sphere with finite conductivity is investigated in the framework of the hydrodynamic approach. We put the sphere into spherical cavity inside the infinite dielectric media, then calculate the energy of vacuum fluctuations in the context of the zeta-function approach. The energy for a single atom is obtained by rarefying media. The Casimir-Polder expression for an atom and plate is recovered in the limit of the infinite radius of the sphere. Assuming a finite radius of the sphere, the interaction energy of an atom falls down monotonic as third power of distance between atom and sphere for short distance and as seventh power for large distance from the sphere.
