1. On the Properties of a Few Electron-Hole system in a Double One-dimensional Harmonic Trap
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysikAbstract : 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

2. Exact Diagonalization of Few-electron Quantum Dots
University essay from Institutionen för datavetenskap, fysik och matematik, DFMAbstract : 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
