Microscopic scattering theory for interacting bosons in weak random potentials
Tobias Geiger, Andreas Buchleitner, Thomas Wellens
We develop a diagrammatic scattering theory for interacting bosons in a three-dimensional, weakly disordered potential. Based on a microscopic N-body scattering theory, we identify…
Inelastic Multiple Scattering of Interacting Bosons in Weak Random Potentials
Tobias Geiger, Thomas Wellens, Andreas Buchleitner
We develop a diagrammatic scattering theory for interacting bosons in a three-dimensional, weakly disordered potential. We show how collisional energy transfer between the bosons i…
Double scattering of intense laser light by two atoms
Vyacheslav Shatokhin, Tobias Geiger, Thomas Wellens +1
This paper analyzes coherent backscattering of intense laser light by two randomly placed distant atoms. Starting from the general two-atom master equation, we analytically derive…
Scattering laser light on cold atoms: multiple scattering signals from single-atom responses
Thomas Wellens, Tobias Geiger, Vyacheslav Shatokhin +1
We deduce the coherent backscattering signal from two distant laser-driven atoms using single-atom equations. In contrast to the standard master equation treatment, this new approa…
