Abstract
We study a spin-polarized degenerate Fermi gas interacting via a p-wave Feshbach resonance in an optical lattice. The strong confinement available in this system allows us to realize one- and two-dimensional gases and therefore to restrict the asymptotic scattering states of atomic collisions. When aligning the atomic spins along (or perpendicular to) the axis of motion in a one-dimensional gas, scattering into channels with the projection of the angular momentum of |m|=1 (or m=0) can be inhibited. In two and three dimensions we observe the doublet structure of the p-wave Feshbach resonance. Both for the one-dimensional and the two-dimensional gas we find a shift of the position of the resonance with increasing confinement due to the change in collisional energy. In a three-dimensional optical lattice the losses on the Feshbach resonance are completely suppressed.
