N ov 2 00 8 Symmetry and reciprocity constraints on diffraction by gratings of quasi - planar particles
نویسندگان
چکیده
Symmetry and reciprocity constraints on polarization state of the field diffracted by gratings of quasi-planar particles are considered. It is shown that the optical activity effects observed recently in arrays of quasi-planar plasmonic particles on a dielectric substrate are due to the reflection of the field at the air-dielectric slab interface and are proportional to this reflection coefficient.

N ov 2 00 8 Neutron diffraction test on spin - dependent short range interaction
In this short note we discuss the possibility to get the constraint on the parameters of short range pseudomagnetic interaction of free neutron with matter from the crystal-diffraction experiment. It is demonstrated that for range of λ < 10 −6 m this constraint can be a few order better than in any other method.
متن کاملDecaying Dark Matter can explain the e± excesses
PAMELA and ATIC recently reported excesses in e± cosmic rays. Since the interpretation in terms of DM annihilations was found to be not easily compatible with constraints from photon observations, we consider the DM decay hypothesis and find that it can explain the e± excesses compatibly with all constraints, and can be tested by dedicated HESS observations of the Galactic Ridge. ATIC data indi...
متن کاملN ov 2 00 0 Shell Effects and Phase Separation in a Trapped Multi - Component Fermi System
Shell effects in the coordinate space can be seen with degenerate Fermi vapors in non-uniform trapping potentials. In particular, below the Fermi temperature, the density profile of a Fermi gas in a confining harmonic potential is characterized by several local maxima. This effect is enhanced for ”magic numbers” of particles and in quasi-1D (cigar-shaped) configurations. In the case of a multi-...
متن کاملN ov 2 00 8 Infinite statistics , symmetry breaking and combinatorial hierarchy
The physics of symmetry breaking in theories with strongly interacting quanta obeying infinite (quantum Boltzmann) statistics known as quons is discussed. The picture of Bose/Fermi particles as low energy excitations over nontrivial quon condensate is advocated. Using induced gravity arguments it is demonstrated that the Planck mass in such low energy effective theory can be factorially (in num...
متن کاملQuasi suppression of higher-order diffractions with inclined rectangular apertures gratings.
Advances in the fundamentals and applications of diffraction gratings have received much attention. However, conventional diffraction gratings often suffer from higher-order diffraction contamination. Here, we introduce a simple and compact single optical element, named inclined rectangular aperture gratings (IRAG), for quasi suppression of higher-order diffractions. We show, both in the visibl...
