We make a detailed study of the moduli space winding number two (k=2) axially symmetric vortices (or equivalently, co-axial composite fundamental vortices), occurring in U(2) gauge theory with flavors Higgs phase, recently discussed by Hashimoto-Tong (hep-th/0506022) and Auzzi-Shifman-Yung (hep-th/0511150). find that it is weighted projective WCP^2_(2,1,1)=CP^2/Z_2. This manifold contains an A_1-type (Z_2) orbifold singularity even though full including relative position smooth. The SU(2)...

We study Bogomol'nyi-Prasad-Sommerfield (BPS) non-Abelian semilocal vortices in $U({N}_{\mathrm{C}})$ gauge theory with ${N}_{\mathrm{F}}$ flavors, ${N}_{\mathrm{F}}>{N}_{\mathrm{C}}$, the Higgs phase. The moduli space for an arbitrary winding number is described using matrix formalism. find a relation between spaces of Seiberg-like dual pairs theories, and $U({N}_{\mathrm{F}}\ensuremath{-}{N}_{\mathrm{C}})$. They are two alternative regularizations parent non-Hausdorff space, which tend to...

The turbulent cross helicity is directly related to the coupling coefficients for mean vorticity in electromotive force and magnetic-field strain Reynolds stress tensor. This suggests that cross-helicity effects are important cases where global inhomogeneous flow structures present. Since such large-scale ubiquitous geo/astrophysical phenomena, effect expected play an role flows. In presence of helicity, vortical motion contributes force. Magnetic-field generation due this called dynamo....

Abstract A rectenna, standing for a rectifying antenna, is an apparatus which generates d.c. electricity from electric fluctuations. It expected to realize wireless power transmission as well energy harvesting environmental radio waves. To such rectification, devices that are made up of internal atomic asymmetry asymmetric junction have been necessary so far. Here we report material spontaneously by fluctuations without using asymmetry. The sample common superconductor lowered crystalline...
