Two-body relaxation of spin-polarized fermions in reduced dimensionalities near a p-wave Feshbach resonance

TL;DR

This paper investigates how reduced dimensionality affects inelastic two-body relaxation in spin-polarized ultracold Fermi gases near a p-wave Feshbach resonance, revealing suppression of relaxation rates in quasi-one-dimensional systems.

Contribution

It demonstrates that in reduced dimensions, especially quasi-one-dimensional setups, the enhancement of inelastic rates near a p-wave resonance is significantly suppressed, offering new avenues for many-body state realization.

Findings

Suppression of inelastic relaxation rates in reduced dimensions

Enhanced control over many-body states in quasi-one-dimensional gases

Potential for observing novel quantum phases

Abstract

We study inelastic two-body relaxation in a spin-polarized ultracold Fermi gas in the presence of a p-wave Feshbach resonance. It is shown that in reduced dimensionalities, especially in the quasi-one-dimensional case, the enhancement of the inelastic rate constant on approach to the resonance is strongly suppressed compared to three dimensions. This may open promising paths for obtaining novel many-body states.
