We present 1.3 and 3.3 mm polarization maps of Orion-KL obtained with the BIMA array at approximately 4′′ resolution. Thermal emission from magnetically aligned dust grains produces the polarization. Along the Orion “ridge” the polarization position angle varies smoothly from about 10◦ to 40◦, in agreement with previous lower resolution maps. In a small region south of the Orion “hot core,” how...

We present circular polarization measurements of circumstellar H2O masers around 2 Mira variables and 4 supergaint stars. Both an LTE and non-LTE method are used to analyze the circular polarization and total intensity spectra and to obtain the magnetic field strength. The non-LTE method is found to be able to reproduce the observations best. Using this, we find fields from a few hundred milliG...

We have made a topological study of cosmic microwave background (CMB) polarization maps by simulating the AMiBA experiment results. A ΛCDM CMB sky is adopted to make mock interferometric observations designed for the AMiBA experiment. CMB polarization fields are reconstructed from the AMiBA mock visibility data using the maximum entropy method. We have also considered effects of Galactic foregr...

The phenomenon of the surface plasmon assisted electromagnetic field concentration in the vicinity of the metal/dielectric interface of a periodically perforated with subwavelength holes arrays plasmonic structure is considered. An increase of the local stationary magnetic field appearing due to the inverse Faraday effect while the heterostructure is illuminated by circularly polarized light is...

Polarization sensitive optical coherence tomography (PS-OCT) is an imaging technique based on light scattering. PS-OCT performs rapid twoand three-dimensional imaging of transparent and translucent samples with micrometer scale resolution. PS-OCT provides image contrast based on the polarization state of backscattered light and has been applied in many biomedical fields as well as in non-medica...

A new approach to the inverse scattering problem proposed by Schroer, is applied to two-dimensional integrable quantum field theories. For any two-particle S-matrix S2 which is analytic in the physical sheet, quantum fields are constructed which are localizable in wedge-shaped regions of Minkowski space and whose two-particle scattering is described by the given S2. These fields are polarizatio...

We report on the observation of magnetic vortex dynamics in response to rotating magnetic fields in submicron platelets. Unlike linear fields or spin polarized currents, which excite both vortex core polarization states, an in-plane rotating field can selectively excite one of the polarization states. We demonstrate by direct imaging with time-resolved scanning x-ray microscopy that the rotatin...

Molecular dynamics (MD) has become a popular method to study ion channels by theoretical means and to provide new insights into their fundamental properties, such as fast conduction and ion specificity. This Perspective deals with one of the current challenges of biomolecular MD studies: the accurate description of polarization. Polarization can be defined as the spatial changes in charge distr...

We study the broadband polarization of hydrogen lines produced by scattering of radiation, in the presence of isotropic electric fields. In this paper, we focus on two distinct problems: a) the possibility of detecting the presence of turbulent electric fields by polarimetric methods, and b) the influence of such fields on the polarization due to a macroscopic, deterministic magnetic field. We ...

We investigate an extension to the concept of degree of polarization that applies to arbitrary electromagnetic fields, i.e., fields whose wave fronts are not necessarily planar. The approach makes use of generalized spectral Stokes parameters that appear as coefficients, when the full 3 x 3 spectral coherence matrix is expanded in terms of the Gell-Mann matrices. By defining the degree of polar...
