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…
One particle quantum equation in a de Sitter spacetime
Rudolf A. Frick
We consider a free particle in a de Sitter spacetime. We use a picture in which the analogs of the Schrödinger operators of the particle are independent of both the time and the sp…
A relativistic superalgebra in a generalized Schroedinger picture
Rudolf A. Frick
We consider a relativistic superalgebra in the picture in which the time and spatial derivative cannot be presented in the operators of the particle. The supersymmetry generators a…
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…
Propagation of a relativistic particle in terms of the unitary irreducible representations of the Lorentz group
Rudolf A. Frick
In a generalized Heisenberg/Schroedinger picture we use an invariant space-time transformation to describe the motion of a relativistic particle. We discuss the relation with the r…
A new Hamiltonian for a massive relativistic particle with spin one in a generalized Heisenberg/Schrödinger picture
Rudolf A. Frick
We consider a particular 4-dimensional generalization of the transition from the Heisenberg to the Schrödinger picture. The space-time independent expansion with respect to the uni…
