SEMINAR ON “ELECTRONIC STRUCTURES”
The convenor of the seminar, J. Mesot (Argonne National Laboratory, USA) gave first an introduction to the Angle Resolved Photoemission Spectroscopy (ARPES) technique applied to the high-temperature superconductors (HTSC). Since the photoemission intensity is directly proportional to the spectral function, which is itself related to the self-energy function, relevant information about the electronic structure of the HTSC materials can be obtained…
