Opis:: We present generalized expressions to calculate the orbital angular momentum for invariant beams using scalars potentials. The solutions can be separated into transversal electric TE, transversal magnetic TM and transversal electromagnetic TE/TM polarization modes. We show that the superposition of non-paraxial vectorial beams with axial symmetry can provide a well-defined orbital angular momentum and that the modes superposition affects the angular momentum flux density. The results are illustrated and analyzed for Bessel beams.

Opis:: Recent studies of short-term phonetic interference suggest that code-switching can lead to momentary increases in L1 influence on L2. In an earlier study using a single acoustic measure (VOT), we found that Czech EFL learners’ pronunciation of English voiceless stops had shorter, i.e. more L1-Czech-like, VOTs in code-switched compared to L2-only sentences. The first aim of the current study was to test the prediction that native listeners would judge the code-switched English productions as more foreign-accented than the L2-only productions. The results provide only weak support for this prediction. The second aim was to test whether more native-like VOT values would correlate with improved accentedness scores. This was confirmed for sentence-initial stops.

Opis:: We report on design and construction of a single-mode-fiber-based Mach-Zehnder interferometer system for measuring single photon indistinguishability from quantum dots emitting in visible spectrum (630±50 nm). The performance of the instrument was tested for its efficiency and usability in single-photon correlation measurements in a proposed experimental setup.
