1. Bose-Einstein Condensation of Magnetic Excitons in Semiconductor Quantum Wells
Sammanfattning : In this thesis regimes of quantum degeneracy of electrons and holes in semiconductor quantum wells in a strong magnetic field are studied theoretically. The coherent pairing of electrons and holes results in the formation of Bose-Einstein condensate of magnetic excitons in a single-particle state with wave vector K. LÄS MER
2. Studies of inhomogeneous Bose-Einstein condensates

3. Problems in Nonlinear Wave Propagation A Walk in Physics from Plasmas to Bose-Einstein Condensates with some Examples of Unifying Themes in Nature
Sammanfattning : Waves are a phenomenon that can be found virtually everywhere in nature. A first description of wave propagation can be given in the linear limit, but the nonlinear regime of propagation is of the utmost importance, also in view of possible applications in several scientific fields.

4. Particle Interferometry in e+e- Annihilation
Sammanfattning : This thesis is the result of three years of work in Lund University, as a member of DELPHI group, at the Elementary Particle Physics Department. The work concerns the study of Bose-Einstein correlations in electron-positron collisions at LEP. LÄS MER
5. Three Pion Interferometry in the NA44 Experiment
Sammanfattning : This thesis presents a three-particle correlation analysis with pions originating from Sulphur-Lead and Lead-Lead collisions at 200 and 158 GeV/c per nucleon respectively, taken by the CERN heavy-ion experiment NA44. The genuine three-body correlation is suppressed in both colliding systems which indicates that the particle production source is partly coherent. LÄS MER
