Abstract or Summary
  • In this work we apply the finite temperature formulation of quantum statistical mechanics to an analysis of the de Haas-van Alphen effect in the quantum limit. A new expression is derived for the differential magnetic susceptibility which clearly shows the individual contributions of zero-temperature and non-zero temperature terms. Interactions have been included in a linearized approximation and contact is made with more heuristic approaches. Approximations in the form of algebraic expressions are made to the temperature correction terms and these are compared to the exact result for the various values of the parameters. The results, which are valid at very low temperatures, may be regarded as the quantum limit analog of the usual DHVA algebraic result. Finally, the self-energy is calculated in Landau level states using a Yukawa potential in the Born approximation. Suggestions are made for a possible extension to a self-consistent Born approximation which would retain full quantum number information as well as incorporate range effects in a realistic fashion.
