Resonant scattering effect in spectroscopies of interacting atomic gases

By M. J. Leskinen, J. Kajala and J. J. Kinnunen

Abstract

We consider spectroscopies of strongly interacting atomic gases, and we propose a model for describing the coupling between quasiparticles and gapless phonon-like modes. Our model explains features in a wide range of different experiments in both fermionic and bosonic atom gases in various spectroscopic methods.Comment: Minor revision. Added 2 pages and 2 figure
