Determination of Electronic Structure Using Spin-Polarized Positrons (E02 (A03))

Subject Area Experimental Condensed Matter Physics
Term from 2010 to 2021
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 107745057
 

Project Description

Spin-polarized 2D-ACAR (Angular Correlation of Annihilation Radiation) is a powerful technique for the measurement of the spin-resolved Fermi surface. We will focus on the electronic structure of elemental crystals, e.g. Pd, Gd and Cr, and of intermetallic compounds such as Heusler alloys in order to obtain an understanding of the electron correlations. The theoretical calculation of the electron momentum density in correlated systems will be developed further by solving a lattice Hubbard-model with short range Coulomb interactions to model electron-electron and electron-positron interactions.
