Anisotropy of incommensurate magnetic excitations in slightly overdoped ${\mathrm{Ba}}_{0.5}{\mathrm{K}}_{0.5}{\mathrm{Fe}}_{2}{\mathrm{As}}_{2}$ probed by polarized inelastic neutron scattering experiments [PDF]

, 2014
Polarized neutron scattering experiments on the slightly overdoped superconductor Ba$_{0.5}$K$_{0.5}$Fe$_2$As$_2$ reveal broad magnetic resonance scattering peaking at approximately 15 meV. In spite of doping far beyond the suppression of magnetic order,

Optical properties of apple skin and flesh in the wavelength range from 350 to 2200 nm [PDF]

, 2008
Optical measurement of fruit quality is challenging due to the presence of a skin around the fruit flesh and the multiple scattering by the structured tissues.

Model of Thomson scattering from z-pinch plasma: Application in experimental design for Plasma Focus

Results in Physics, 2022
The present work develops a model of Thomson scattering (TS) for z-pinch plasmas. Sustained on the phenomenology observed in dynamical-pinch discharges of interest in fusion studies, the plasma dynamics is modeled by axisymmetric bi-Maxwellian velocity ...

Magnetic Excitations of Undoped Iron Oxypnictides [PDF]

, 2009
We study the magnetic excitations of undoped iron oxypnictides using a three-dimensional Heisenberg model with single-ion anisotropy. Analytic forms of the spin wave dispersion, velocities, and structure factor are given.

Antenna-enhanced and polarization sensitive photoresponse in arrays of silicon P–i–N nanowires

New Journal of Physics, 2013
We analyze a novel antenna effect that resonantly enhances the photocurrent response of end-contacted P–i–N junction nanowire gratings, due to coupling of incident radiation into the grating's multiple-scattering electromagnetic modes.

Anisotropy of the incommensurate fluctuations in Sr2RuO4: a study with polarized neutrons

, 2003
The anisotropy of the magnetic incommensurate fluctuations in Sr2RuO4 has been studied by inelastic neutron scattering with polarized neutrons. We find a sizeable enhancement of the out of plane component by a factor of two for intermediate energy ...

Ultra low-loss super-resolution with extremely anisotropic semiconductor metamaterials

AIP Advances, 2018
We investigate the mechanisms for the reduction of losses in doped semiconductor multilayers used for the construction of uniaxial metamaterials and show that maximizing the mean scattering time of the doped layers is key to spectrally isolating losses ...

Polarization Dependence of Anomalous X-ray Scattering in Orbital Ordered Manganites

, 1998
In order to determine types of the orbital ordering in manganites, we study theoretically the polarization dependence of the anomalous X-ray scattering which is caused by the anisotropy of the scattering factor.
