Nanoscale Waveguide Beam Splitter in Quantum Technologies
Usually in quantum optics, the theory of large- and small-scale waveguide beam splitters is the same. In this paper, it is shown that the theory of the nanoscale waveguide beamsplitter has a significant difference from a similar device, but of a larger scale. It is shown that the previously known theory of the waveguide beam splitter is a particular case of the theory presented here. The wave function at the output ports of the nanoscale beam splitter is analyzed. The results obtained are sensitive to the size of the beam splitter, the coupling parameter of the two waveguides, and the degree of nonmonochromaticity of the photons entering the first and second ports of the beam splitter. The results are important for quantum technologies using a nanosized beam splitter.

Сверхгидрофобное покрытие из углеродных наночастиц луковичной структуры
For the first time a superhydrophobic coating based on carbon nano-onions (multilayer fullerenes) synthesized through a cheap and technological method was obtained. Two simple and easily reproducible techniques of application were suggested. An opportunity of using the coating to control the composition and humidity of air was explored. Anti-icing properties were researched.
