In the Standard Model of particle physics, the Brout–Englert–Higgs mechanism provides mass to elementary particles. While physicists are carrying out direct studies of the Higgs boson to test this mec...
Polarisation singularities of non-paraxial Gaussian vortex beams diffracted by an annular aperture
polarisation singularities non-paraxial annular aperture C-points
2013/7/3
Based on the vectorial Rayleigh–Sommerfeld diffraction integrals, the propagation expressions for non-paraxial Gaussian vortex beams diffracted by an annular aperture are derived, and are used to anal...

The leading hadronic vacuum polarisation lattice
2011/1/7
After discussing the relevance of a first principles theory-prediction of the hadronic vacuum polarisation for Standard Model tests, the theoretical challenges for its computation in lattice QCD are r...

Optically induced spin polarisation NV- centre in diamond: role electron-vibration interaction
2010/11/22
The novel aspect of the centre (NV−) in diamond is the high degree of spin polarisation achieved through optical illumination. In this paper it is shown that the spin polarisation occurs as a co...
