1. Rotational Properties of Lee-Huang-Yang Bosonic Condensates from One to Two Dimensions
Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenSammanfattning : This thesis covers the work of a numerical examination of the rotational properties of a two-component Bose-Einstein condensate (BEC) utilizing the beyond mean-field extended Gross-Pitaevskii equation for a specified set of parameters. These parameters are chosen to cancel the strength of the mean-field interaction, which makes the system predominantly governed by the next order beyond the mean-field Lee-Huang-Yang (LHY) term.

2. On the Properties of a Few Electron-Hole system in a Double One-dimensional Harmonic Trap
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysikSammanfattning : 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. LÄS MER
