Measurement of 3-body losses in a quasi-1D $^6$Li gas near a $p$-wave Feshbach resonance

ORAL

Abstract

$P$-wave interactions are known to lead to intriguing quantum phenomena such as $p + ip$ topological superfluids and Majorana fermions. However, the experimental detection of these phenomena in ultracold atomic gases remains a challenge due to the severe atom losses from three-body recombination collisions near the p-wave Feshbach resonance in a 3D atomic gas. It has been recently predicted\footnote{Lihong Zhou and Xiaoling Cui, Phys. Rev. A 96, 030701 (2017).} that such effects could be suppressed by introducing 1D confinement, thus leading to the formation of p-wave atom pairs. To study the stability of atom pairs, we will measure the three-body loss rate with spin-polarized $^6$Li atoms in the Zeeman ground state $\vert f=\frac{1}{2}, m_f=\frac{1}{2} \rangle$. With a two-dimensional compensated optical lattice, we can introduce a quasi-1D confinement. We will report the result of the three-body loss rate measurement in different dimensions.
