Abstract:Using the combined Density Functional and Dynamical Mean Field theory we study relativistic corrections to the Fermi surface of palladium. We find indeed that relativistic corrections create a small hole pockets at the L-symmetry points. Furthermore we show that the computed two dimensional Angular Correlation of Electron Positron Annihilation Radiation (the so called 2D-ACAR) clearly demonstrates the existence of these L-hole pockets, which remains robust against electronic correlations. A 2D-ACAR experiment … Show more
