University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik
Abstract : One of the most important concepts in condensed matter physics is that of ``quasi particles''. The exciton is one such quasi particle. In semi-conductors, excitons are formed by the excitation of electrons from valence band to conduction band, which creates holes in the valence band. READ MORE
University essay from Linnéuniversitetet/Institutionen för datavetenskap, fysik och matematik, DFM
Abstract : We consider a system of few electrons trapped in a two-dimensional circularquantum dot with harmonic confinement and in the presence of ahomogeneous magnetic field, with focus on the role of e-e interaction. Byperforming the exact diagonalization of the Hamiltonian in second quantization,the low-lying energy levels for spin polarized system are obtained. READ MORE
