Unified description of dynamics of a repulsive two-component Fermi gas
We study a binary spin mixture of a zero-temperature repulsively interacting Li 6 atoms using
both the atomic-orbital and density-functional approaches. The gas is initially prepared in a …

Collective modes of trapped Fermi gases with in-medium interaction
S Chiacchiera, T Lepers, D Davesne, M Urban - Physical Review A—Atomic …, 2009 - APS
Due to Pauli blocking of intermediate states, the scattering matrix (or T matrix) of two
fermionic atoms in a Fermi gas becomes different from that of two atoms in free space. This …
