text: Spin mixtures of degenerate fermions are a cornerstone of quantum many-body
physics, enabling superfluidity, polarons, and rich spin dynamics through s-wave
scattering resonances. Combining them with strong, long-range dipolar interactions
provides highly flexible control schemes promising even more exotic quantum phases.
Recently, microwave shielding gave access to spin-polarized degenerate samples
of dipolar fermionic molecules, where tunable p-wave interactions were enabled
by field-linked resonances available only by compromising the shielding (due to
experimental limitations). Here, we study the scattering properties of a fermionic
dipolar spin mixture and show that a universal s-wave resonance is readily accessible
without compromising the shielding. We develop a universal description of the
tunable s-wave interaction and weakly bound tetratomic states based on the microwave-field
parameters. The s-wave resonance paves the way to stable, controllable and strongly-interacting
dipolar spin mixtures of deeply degenerate fermions and supports favorable conditions
to reach this regime via evaporative cooling.
