Abstract

The spin-orbit coupling in a deformed system is studied by approximating the Schrödinger equation semiclassically. The discrete character of spin is preserved and WKB techniques are used for the coupled two-component wave equations. Thus, contrary to other approaches, spin is not treated similar to a classical angular momentum. Information about the periodic orbits is extracted from Fourier transform of the quantum mechanical spectra and compared to classical calculations. Planar motion exhibiting mode conversion and non-planar motion, for which Berry′s phase is important, are investigated. For planar orbits, the semiclassical method is successfully corrected for mode conversion.

    Besides the various semiclassical scenarios which we have described in this article there is an additional strategy for taking the semiclassical limit of multi-component wave equations. In this approach one does not treat the matrix degrees of freedom, i.e. colour and spin, dynamically but rather considers polarised Hamiltonians, which describe a particle with the spin or colour projection locked to the “direction” of the external gauge field, see e.g. [40,41,15,42]. Such an approach may also prove useful in the case of the QCD Dirac operator.
