Abstract: In the present work we have demonstrated a possibility for real-time operation by orbital an-gular momentum (OAM) of optical beams via Pockels effect in solid crystalline materials. Basing o...
Spin Hall effect of light in metallic reflection

2011/8/29
In an oblique section of a paraxial beam with angular momentum, the beam center of gravity (CG) is shifted with respect to its position in the normal cross section. We relate this shift with the inter...

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...

We show that the interplay between spin-changing collisions and quadratic Zeeman coupling
provides a novel mechanism for the formation of repulsively bound composites in high-spin fermions,which we i...
Despite weak spin-orbit coupling and an indirect band gap, significant optical spin orientation
is possible in silicon. We show this by performing full band-structure calculations of the phonon-assis...
