- Description: D.Litt. et Phil. , The aim of this investigation is to provide support to the growing evidence that people's paradigms directly influence the way differences are managed. Adherence to the old or Newtonian model has seemingly led to a restricted ability to deal with differences. Adherence to the new or quantum model, on the other hand, appears to facilitate not only the understanding of why there are so many differences and why they should be "celebrated" (topic of the American Counselling Association's 1995 Conference, Denver), but also encourages people to freely and nonjudgementally acknowledge, explore and integrate these differences. As a first step toward achieving this aim, a review of the literature regarding the existence of differences, the perceived causes of differences, and the perceived ways of managing differences in interpersonal relationship up to the present time will be provided. Secondly, the importance of paradigms in general, and of the natural scientific paradigms in particular, will be illustrated. Concepts of Newtonian and quantum physics that are considered relevant to the investigation will be described under this heading. Thirdly, the rationale of the exploratory, or qualitative study will be outlined. Fourthly, a chapter linking the natural scientific paradigms . to the discipline of psychology will be presented. Psychological analogies of Newtonian and quantum concepts will be put forward as well as examples of Newtonian and quantum psychology. Finally, implications of the described and discussed findings of Newtonian and quantum physics on the management of psychological differences will be explored, so that the 'celebration' and integration of differences can, indeed, be promoted.

Magnetic and electric properties of the Hubbard model for the BCC lattice

- Description: Ph.D. (Theoretical Physics) , In this thesis the thermodynamic and magnetic properties of the non-degenerate Hubbard model are investigated. The underlying lattice is the bcc-lattice. The results obtained will therefore be especially applicable to systems with a single, narrow conduction band. As a check the thermodynamic properties of the model system are first calculated in two limiting cases, namely the free electron 'gas and the strong coupling limit. In this process, use is made of results related to Wick's Theorem, which are developed in an appendix. Another check is provided by the calculation of the ground state spectrum of a finite, fourpoint system. These results are obtained using standard group theory techniques. The ground state for the non-degenerate Hubbard model is solved approximatively by a variational method. Once again the necessary version of Wick's theorem is developed in an appendix. The ,results for the neutral case (i.e. a half-filled band) is in agreement with other studies on AB-lattices: It is found that the system is anti ferromagnetic for all values of the coupling constant. The quarter and three-quarter filled cases, hitherto not studied because of numerical complexity, yield a completely different picture. For increasing values of the coupling constant second order phase transitions are found, first from the para- to the ferromagnetic phase and then from the ferro- to the anti ferromagnetic phase. The only results available in the literature related to this case were obtained for an almost half-filled band in the strong-coupling limit and qualitatively support the findings of the present study. It is proposed that the simple theory used in this study be extended for use in physical systems such as Cr.

Entanglement and energy level crossing of spin and Fermi Hamilton operators

- Description: M.Sc. (Applied Mathematics) , Entanglement is a quantum resource with applications in quantum communication as well as quantum computing amongst others. Since quantum entanglement is such an abstract concept numerous mathematical measures exist. Some of these have a purely theoretic purpose whereas others play a role in describing the magnitude of entanglement of a system. In quantum systems energy level crossing may occur. Energy levels in quantum systems tend to repel each other so when any type of degeneracy occurs where the energy levels coalesce or cross it is of interest to us. Two such points of degeneracy are exceptional and diabolic points. When these occur it is useful to investigate these points in specific systems and observe level crossing. In this thesis we mainly investigate the relationship between entanglement, energy level crossing and symmetry as well as the exceptional and diabolic points of specific systems. We are especially interested in systems described by spin and Fermi operators.

- Description: To find the discrete symmetries of a Hamilton operator ˆH is of central importance in quantum theory. Here we describe and implement a brute force method to determine the discrete symmetries given by permutation matrices for Hamilton operators acting in a finite-dimensional Hilbert space. Spin and Fermi systems are considered as examples. A computer algebra implementation in SymbolicC++ is provided.
