Quasiparticles, coherence, and nonlinearity: Exact simulations of rf spectroscopy of strongly interacting one-dimensional Fermi gases
Physical Review A. Atomic, Molecular, and Optical Physics
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 rule result are found to suppress the pairing contribution to the RF line shifts. We compare the coherent rotation and quasiparticle descriptions of RF-spectroscopy which are analogous to NMR experiments in superfluid ^3He and tunneling in solids, respectively. We suggest that RF-spectroscopy in ultracold gasesdoi:10.1103/physreva.78.023602 fatcat:6zgls37r65exbg32zqwuygljvy
