1. 1. Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs

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

   Author : Emil Adam Jonatan Östberg; [2023]
   Keywords : skyrmion; skyrmions; NEGF; freen s function; quantum transport; non-equlibrium; topology; topological charge; skyrmionics; current induced; open system; Physics and Astronomy;

   Abstract : A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. READ MORE

3. 2. Magnetization dynamics in nanorings

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

   Author : Simon Ydman; [2015]
   Keywords : Kondo effect; quantum rings; doniach phase diagram; exact diagonalization; Physics and Astronomy;

   Abstract : This thesis investigates numerically the out of equilibrium properties of quantum rings with magnetic impurities, using the periodic Anderson model (PAM). The model is a simple template for the discussion of the physics of regular arrays of rare-earth impurities in metallic hosts. READ MORE
