Abstract
A generalization of symmetrized density matrices in combination with t he technique of generating functions allows one to calculate the parti tion function of identical particles in a parabolic confining well. Ha rmonic two-body interactions (repulsive or attractive) are taken into account. Also the influence of a homogeneous magnetic field, introduci ng anisotropy in the model, is examined. Although the theory is develo ped for fermions and bosons, special attention is paid to the thermody namic properties of bosons and their condensation.
