A model of the two-dimensional quantum harmonic oscillator in an background
Rudolf Frick
In this paper we study a model of the two-dimensional quantum harmonic oscillator in a 3-dimensional anti-de Sitter background. We use a generalized Schrödinger picture in which th…

Propagator for a spin 1/2 particle in terms of the unitary representations of the Lorentz group
Rudolf A. Frick
In this paper we extend our previous result on the description of the partcle motion in a generalized Heisenberg picture to a relativistic fermion. The operators of the Lorentz alg…
