The spin-polarisation parameters for photoelectrons from lead atoms (6?6p2)J,0 were measured in the wavelength range between the second threshold [Pb+ (6s26p) 2P3i2] and 100 nm in an angle-resolving experiment using circularly polarised vuv-radiation from the storage ring BESSY. Beyond this threshold (2 = 135.3 nm), the photoionisation cross section is strongly perturbed by autoionisation reson...

We present a system which uses a single spatial light modulator to control the spin angular momentum of multiple optical traps. These traps may be independently controlled both in terms of spatial location and in terms of their spin angular momentum content. The system relies on a spatial light modulator used in a "split-screen" configuration to generate beams of orthogonal polarisation states ...

We compare two rotationally invariant decomposition techniques on linear polarisation data: the spin-2 spherical harmonic decomposition in two opposite parities, the Eand B-mode, and the multiscale analysis of the gradient of linear polarisation, |∇P |. We demonstrate that both decompositions have similar properties in the image domain and the spatial frequency domain. They can be used as compl...

We present the results of simultaneous optical polarimetry and EUV spectroscopy and photometry of PQ Gem, a magnetic cataclysmic variable which shows observational properties of the strongly magnetic AM Her class, as well as the weaker eld DQ Her stars. The EUV spectrum of PQ Gem is weak, showing continuum blueward of 80 A and a few possible weak emission lines due to Mg, Si, and Ne. The EUV li...

Results are presented on inclusive measurements of the spin structure function g 1 (x). The world's data on spin–dependent deep inelastic scattering are summarized. Results from recent Next–to–Leading Order (NLO) QCD analyses are given. They provide another successful test of QCD. The uncertainties arising from the low–x extrapolation of the inclusive data in absence of any measurement prevent ...

The question of spin-charge separation in two-dimensional lattices has been addressed by numerical simulations of the motion of one hole in a half-filled band. The calculations have been performed on finite clusters with Hubbard and t-J models. By comparing the time evolution of spin and charge polarisation currents in one and two dimensions, evidence in favor of spin-charge separation in two d...

stability of the ;-; stacking interactions in the substituted-coronene||cyclooctatetraene complexes wasstudied using the computational quantum chemistry methods (where || denotes ;–; stackinginteraction, and substituted-coronene is coronene which substituted with four similar x groups; x =oh, sh, h, f, cn, and no). there are meaningful correlations between changes of geometricalparameters and t...
