Recently, many people have found polarisation features in the SCIAMACHY Level-1c spectrum, in the form of jumps. The jumps are found to be caused by the polarisation correction algorithm, which is evidenced by the fact that the jumps occur only when the polarisation correction is switched on, and only at cluster transitions where the integration time changes. We explain the origin of the jumps,...

Relativistic Calculation of Structure Functions b 1,2 (x) of the Deuteron. Abstract The structure functions b D 1,2 (x) of the deuteron are studied within covariant approach. It is shown that usual nonrelativistic convolution model result in incorrect behavior of this structure functions at small x and violates the exact sum rules. Realistic calculations are carried out with the Bethe-Salpeter ...

We find the leading order result for the anapole form factor of the deuteron using effective field theory. The momentum dependence of the anapole form factor is different from that of the matrix element of the strange currents in the deuteron, which may provide a way for disentangling these two competing effects when analyzing parity violating electron-deuteron scattering experiments. We give c...

The complex Kohn variational principle and the (correlated) hyperspherical harmonics method are applied to study the proton–deuteron elastic scattering at energies above the deuteron breakup threshold. Results for the elastic cross section and various elastic polarization observables have been obtained by fully taking into account the long–range effect of the Coulomb interaction and using a rea...

The deuteron form factors are calculated in the framework of the relativistic nucleon-meson dynamics. The relativistic effects change considerably the Sand D-waves of the deuteron, result in the dominating extra component in the deuteron wave function and generate the contact interaction between the nucleon, mesons and photon. The prediction for the polarization observable t20 is in good agreem...

We develop a theoretical model to study the Intensity-Intensity correlation of polarisation entangled photons emitted in a biexciton-exciton cascade. We calculate the degree of correlation and show how polarisation correlations are affected by the presence of dephasing and energy level splitting of the excitonic states. Our theoretical calculations are in agreement with the recent observation o...

In this paper we question the common wisdom that more polarised voters’ opinions imply larger policy polarisation. We analyse a voting model in which the source of the polarisation in voters’ opinions is “correlation neglect”, that is, voters neglect the correlation in their information sources. Our main result shows that such polarisation in opinions does not necessarily translate to policy po...

In this paper the use of a crossed-dipole array is proposed in joint space-time channel estimation for asynchronous multipath DS-CDMA systems. The polarisation diversity offered by such an array, unlike linearly polarised arrays, is shown to provide a better and more consistent estimation which is less sensitive to the signal polarisation. By utilising the polarisation information inherent in t...

We assume that due to their small binding energy, deuterons from the midrapidity region cannot survive inside fireballs created in ultrarelativistic nuclear collisions. All observed deuterons are thus expected to be created from a neutron proton pair at freeze-out by coalescence. This coalescence process involves small relative momenta and is thus a non-relativistic phenomenon. Switching to cen...
