The paper supplies numerical information on coherent effects of bremsstrahlung and electron pair production in diamond crystals in the energy range from 1 to 40 GeV. The information is collected in a number of graphs and tables showing the intensity and polarization of bremsstrahlung and the cross section and asymmetry ratio for pair production as a function of crystal orientation. The basic fo...

We consider emission of a photon by an electron in the field of a strong laser wave. Polarization effects in this process are important for a number of physical problems. We discuss a probability of this process for circularly polarized laser photons and for arbitrary polarization of all other particles. We obtain the complete set of functions which describe such a probability in a compact cova...

Spatial field correlation functions represent a key quantity for the description of mesoscopic phenomena in disordered media and the optical characterization of complex materials. Yet many aspects related to the vector nature of light waves have not been investigated so far. We study theoretically the polarization and coherence properties of electromagnetic waves produced by a dipole source in ...

We present analytical calculation of the rst seven moments of the heavy quark vacuum polarization function in the three-loop order. The obtained results are compared against the asymptotic formulas following from the threshold singulari-ties. We also discuss the dependence of the moments within the BLM procedure.

Characteristic polarization state theory is restudied for the symmetric coherent Sinclair scattering matrix case. First, the geometric relations of the characteristic polarization states on the Poincaré sphere are derived. Based on these relations, simple formulas are given for all of the characteristic polarization states of this Sinclair matrix in Stokes vector form. From the formulation, it ...

We investigate the role of polarization-photon coupling (specifically, polarization-oscillation-induced radiation electric field) in excitation ferroelectric thin films by an ultrafast terahertz field pulse. Analytical formulas are developed to predict how frequencies and relaxation time three-dimensional soft mode phonons (intrinsic polarization oscillation) modulated epitaxial strain. Ultrafa...

A broadband gradient index (GRIN) metamaterial lens for gain enhancement of circularly polarized antennas has been automatically designed, fabricated and investigated. The GRIN metamaterial lens consists of an isotropic dielectric plate with a corresponding distribution of deep-subwavelength drill holes each with the same diameter. Such drill holes have a negligible influence on both the polari...

We investigate quasi-free Hadamard states defined via characteristic initial data on null cones centred at the axis of symmetry in spherically symmetric space-times. characterize necessary singular behaviour boundary two-point functions such that one can define non-linear observables this and give formulas for calculation these observables. These results extend earlier characterizations definin...

Image method is a classical method for finding electrostatic potentials in dielectric or conducting objects with special geometries. The image method provides simple and analytical formulas to represent the reaction field on a charge in an object as a result of the polarization effect from the surrounding material. In this paper, we will provide an overview of the classical results of image met...
