Experiments are planned to improve the sensitivity of μ − e conversion from the current ∼ 10 to ∼ 10 − 10. If the muon (bound to the nucleus) could be polarised, a spin asymmetry of the final state electron is sensitive to CP violating phases on lepton flavour violating operators. This is similar to extracting phases from asymmetries in the final state spin and phase space distributions of μ → ...

Photoelectron spin-polarisation measurements of In(5s2 5p) 2P,12 were performed in the autoionisation region of the 5s5p2-configuration using monochromatic circularly polarised synchrotron radiation at the electron storage ring BESSY. The autoionising levels are analysed in terms of partial cross section, dipole matrix elements and phase-shift differences. In addition the measured photoelectron...

The 1–loop effective Lagrangian for a massive scalar field on an arbitrary causality violating spacetime is calculated using the methods of Euclidean quantum field theory in curved spacetime. Fields of spin 12 , spin 1 and twisted field configurations are also considered. In general, we find that the Lagrangian diverges to minus infinity at each of the nth polarised hypersurfaces of the spaceti...

When a left-circularly polarised Gaussian light beam, which has spin angular momentum (SAM) J(sp) = sigmah = 1h per photon, is incident along one of the optic axes of a slab of biaxial crystal it undergoes internal conical diffraction and propagates as a hollow cone of light in the crystal. The emergent beam is a superposition of equal amplitude zero and first order Bessel like beams. The zero ...

Proximity exchange interaction between graphene electrons and nearby magnetic insulators paves the way to create spin-polarised currents for spintronics applications. Different ferro- ferrimagnetic insulators, such as europium chalcogenides, yttrium iron garnet cobalt ferrite, have been proposed in literature induce correlations graphene. We theoretically study electronic transport properties o...

The HERMES experiment at DESY, Hamburg used the HERA 27.6GeV electron/positron polarised beam to study the structure of the nucleon. Deeply Virtual Compton Scattering (DVCS) provides access to Generalised Parton Distributions (GPDs) via measured azimuthal asymmetries. Data was collected from 1995 to 2007 with both longitudinally and transversely polarised gas tar-gets(H, D or heavier nuclei), w...

COMPASS is a fixed-target experiment on the SPS M2 beamline at CERN. Its 6 LiD target can be polarised both longitudinally and transversally with respect to the longitudinally polarised 160GeV/c µ + beam. Approximately 20% of the beam-time in 2002, 2003 and 2004 was spent in the transverse configuration, allowing the first measurement of both the Collins and Sivers asymmetries on a deuterium ta...

Polarisation of cells is crucial for vectorial transport of ions and solutes. In literature, however, proteins specifically targeted to the apical or basolateral membrane are often studied in non-polarised cells. To investigate whether these data can be extrapolated to expression in polarised cells, we studied several membrane-specific proteins. In polarised MDCK cells, the Aquaporin-2 water ch...

Azimuthal single-spin asymmetries (SSA) in semi-inclusive electroproduction of πmesons and charged K-mesons in deep-inelastic scattering of positrons and electrons on a transversely polarised hydrogen target were observed. Significant SSA amplitudes for both the Collins and the Sivers mechanism are presented for the full data set recorded with transverse target polarisation at the HERMES experi...
