1. 1. Combining the GW Approximation with the Hubbard I Approximation for strongly correlated materials

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Torsten Strunck; [2019]
   Keywords : GWA; GW Approximation; HIA; Hubbard I Approximation; Hubbard-I Approximation; Hubbard model; DMFT; Dynamical Mean Field Theory; strongly correlated materials; electron correlations; solid state physics; Physics and Astronomy;

   Abstract : In this thesis, the GW approximation (GWA, Green's function G times screened interaction W) and the Hubbard I approximation (HIA) are combined in a non-self-consistent one-shot calculation to determine the electronic structure of a one-dimensional strongly-correlated model. The scheme was chosen to incorporate both screening effects through the GWA and strong on-site correlations through the atomic HIA. READ MORE

3. 2. A statistical investigation of Bursty Bulk Flow event dynamics in the Earth magnetotail

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Thomas Zhang; [2014]
   Keywords : Bursty Bulk Flow; Cluster; Curlometer method; Lorentz force;

   Abstract : A statistical investigation of the relationship between Lorentz force and Bursty Bulk Flow event (BBF) spatial location in the magnetotail is undertaken. Data is obtained in situ by the ESA Cluster II mission during the period July to October 2004. Firstly, a short introduction to BBFs and the Cluster mission is presented. READ MORE
