Contribution of spontaneous polarization and its fluctuations to refraction of light in ferroelectrics

the polarization fluctuations. A method has been proposed for calculating the magnitude and temperature dependence of the root-mean-square fluctuations of the polarization (short-range local polar order) ...

Correlation radius of polarization fluctuations in the disordered ferroelectrics.

We calculate correlation radius of polarization fluctuations in the disordered ferroelectrics. The consideration is performed in the model suitable for relaxor ferroelectrics. We consider reference Burns phase in a mean field approx...

Study of Time Fluctuation of Polarization of Polarization Preserving Fibers

This paper deals with the measurement of SOP (State of Polarization) of polarization preserving fiber and its time stability. Linear or circular polarized light output intensity for different positions of output polariz...

X-ray polarization fluctuations induced by cloud eclipses in active galactic nuclei

We find that X-ray polarimetry is particularly adapted to probing X-ray eclipses due to Compton-thin and Compton-thick gas clouds. Polarization measurements would distinguish between intrinsic intensity fluctuations and external ecl...

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

The anisotropy of the magnetic incommensurate fluctuations in Sr2RuO4 has been studied by inelastic neutron scattering with polarized neutrons. We find a sizable enhancement of the out-of-plane component by a factor of 2 for interme...

Scale-dependent Polarization of Solar Wind Velocity Fluctuations at the Inertial and Kinetic Scales

We study the polarization properties of the velocity fluctuations in solar wind of perpendicular to parallel velocity fluctuations in the inertial range is smaller than the equivalent ratio for magnetic fluctuations

Polarization of photoluminescence excitation and emission spectra of silicon nanorods within single Si/SiO2 nanowires

Polarization properties of individual silicon nanowires are studied using the polarization of the exciting laser and the analyzer to characterize the polarization and oriented parallel to the Si substrate. Due to the fl...

Alfvénic fluctuations in the expanding solar wind: Formation and radial evolution of spherical polarization

fluctuations and their evolution during radial expansion. We assume a strictly radial: Magnetic field fluctuations evolve toward a state with low-amplitude variations in the amplitude B = |B| and tend to a spherical polarizatio...

Tolerance of pennate diatoms (Bacillariophyceae) to experimental freezing: comparison of polar and temperate strains

Although polar regions are characterised by extreme environment conditions with overall low tempera-tures and often pronounced diurnal to seasonal temperature fluctuations, diatoms (Bacillariophyceae)thrive in a wide range of nonmar...
