Adiabatic spin-dependent momentum transfer in an SU(๐) degenerate Fermi gas
We introduce a spin-orbit coupling scheme, where a retroreflected laser beam selectively diffracts two spin components in opposite directions.

Spin sensitivity is provided by sweeping through a magnetic-field sensitive transition while dark states ensure that spontaneous emission remains low. The scheme is adiabatic and thus inherently robust.
This tailored spin-orbit coupling allows simultaneous measurements of the spin and momentum distributions of a strontium degenerate Fermi gas, and thus opens the path to momentum-resolved spin-correlation measurements on SUโก(๐) quantum magnets.
