Ultracold atomic gases provide a versatile platform for studying few- and many-body interactions in quantum systems. p-Wave interactions, where colliding particles share one unit of angular momentum, can be isolated and tuned in spin-polarized degenerate Fermi gases using a Feshbach resonance. In this work, we demonstrate the ability to engineer the in-plane scattering symmetry of p-wave interacting gases in planar traps by controlling out-of-plane motional excitations and an external magnetic field. Radiofrequency spectroscopy probes short-range spatial correlations, which determine the in-plane scattering symmetry via a characteristic power-law scaling. In this talk, I will describe low-energy scattering in systems of ultracold identical fermions, and how motional excitations in the planar trapping potential dictate the possible scattering symmetries. The symmetry control demonstrated here could be extended to bosonic systems and higher angular momentum interactions.
