6. Green's Functions Investigations in Quantum Transport Geometries
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : In this thesis we employ the non-equilibrium Green’s function (NEGF) method to study both finite and infinite systems. We develop a codebase capable of computing the steady state interacting NEGF in open systems, i.e. READ MORE

10. Electronic states in semiconductor double quantum dots and quantum rings - Theory and tight-binding modeling
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : In recent experiments on semiconductor nanowires and quantum dots, enhanced g-factors up to several times the bulk value have been measured [1] [2]. The enhancement is attributed to orbital contributions g∗orb to the effective g-factor g∗ = g∗spin+g∗orb from the coupling of the high angular momentum ring-like states to the magnetic field.
