Many-body molecule formation at a domain wall in a one-dimensional strongly interacting ultracold Fermi gas
arXiv:2105.00439 · doi:10.1103/PhysRevA.105.013314
Abstract
We analyze how the presence of the bound state on top of strong intercomponent contact repulsion affects the dynamics of a two-component ultracold Fermi gas confined in a one-dimensional harmonic trap. By performing full many-body numerical calculations, we retrieve dynamics of an initially phase separated state that has been utilized to excite the spin-dipole mode in experimental settings. We observe an appearance of pairing correlations at the domain wall, heralding the onset of a molecular faction at the interlayer between the components. We find that such a mechanism can be responsible for the stabilization of the phase separation.
