1. The Quantum Hall Effect
Kandidat-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : The quantum Hall effect occurs when a conductor carrying a current is placed in a perpendicular magnetic field. If certain conditions are met, such as strong magnetic field and low temperature, the resistivity becomes quantised, taking values of integer or fractional multiples of h/e2. LÄS MER
2. Anyons in (1 + 1) dimensions and the deformed Calogero-Sutherland model
Master-uppsats, KTH/Teoretisk fysikSammanfattning : This thesis deals with a conformal field theoretical treatment of abelian anyons in (1 + 1)-dimensions and their relation to the integrable Calogero-Sutherland models. We generalize previous work relating anyons to the Calogero-Sutherland model by showing that the correlation function of the anyon field operators corresponds to the eigenfunctions of the deformed Calogero-Sutherland model.

3. Exact Diagonalization of Few-electron Quantum Dots
Kandidat-uppsats, Institutionen för datavetenskap, fysik och matematik, DFMSammanfattning : 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. LÄS MER
