Scattering of a particle on the $q$-deformed Euclidean space

Quantum Physics 2022-08-12 v1

Abstract

We develop a formalism for the scattering of a particle on the qq-deformed Euclidean space. We write down qq-versions of the Lippmann-Schwinger equation. Their iterative solutions for a weak scattering potential lead us to qq-versions of the Born series. With the expressions for the wave functions of the scattered particle, we can write down S-matrix elements. We show that these S-matrix elements satisfy unitarity conditions. Considerations about the interaction picture for a quantum system in the qq-deformed Euclidean space and a discussion of a qq-version of time-dependent perturbation theory conclude our studies.
