Ab-initio Relativistic Spin-Polarised Theory of Angle-Resolved Photoemission

Arthur Ernst (Max Planck Institute, Halle) visited Daresbury where Prof Strange is an honorary scientist. He was developing real space methods for calculating the electronic structure and photoemission of nanoparticles. Through Prof Strange’s research and book he is recognised as a leading authority on relativistic quantum theory. Together they realised that a relativistic generalisation of his theory would yield new results (photon polarisation dependent photoemission). A collaboration was initiated and this paper reports that work. It clearly demonstrates a reputation appropriate to collaborate with internationally leading centres. This work was a research highlight in the EU Psi-K network newsletter.
