Summary on Grant Application Form |

The proposed research will help to establish the main properties of vortex structures. Quantitative comparison of the theoretical results with numerous experimentally measured vortex properties and comparison with the critical temperature of superfluid and superconductors in confined geometries will contribute a novel and unique approach to this research. The study on quasiparticle scattering will lead to a realistic theory of quantum evaporations which will produce quantitative results (the probabilities of the various surface scattering processes) which will be compared to experimental data - we stress here that this will not be a direct comparison: for various reasons, experimentalists cannot measure probabilities. Recent progress in techniques has made it possible to study experimentally (mesoscopic and nanoscopic) superconducting samples of micrometer and nanometer dimensions (Geim and et al) and mesoscopic droplets of quantum liquids (Saunders, Gasparini and others). This has led, and is leading, to the discovery of new phenomena which have already been and will be observed and which require urgent theoretical explanations. Our theoretical studies will not only help to explain some of the new discoveries, but also predict many new others which, in turn, will stimulte new experiments. The importance of boundary effects in such small systems for generation of topological defects will be thoroughly investigated.
