Expansion dynamics of the Fulde-Ferrell-Larkin-Ovchinnikov state
J. Kajala, F. Massel, P. Torma
We consider a two-component Fermi gas in the presence of spin imbalance, modeling the system in terms of a one-dimensional attractive Hubbard Hamiltonian initially in the presence…

Resonant scattering effect in spectroscopies of interacting atomic gases
M. J. Leskinen, J. Kajala, J. J. Kinnunen
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…

Quasiparticles, coherence and nonlinearity: exact simulations of RF-spectroscopy of strongly interacting one-dimensional Fermi gases
M. J. Leskinen, V. Apaja, J. Kajala +1
We consider RF-spectroscopy of ultracold Fermi gases by exact simulations of the many-body state and the coherent dynamics in one dimension. Deviations from the linear response sum…
