Spin-Orbit coupling in a Lithium-6 quasi-2D Fermi gas

自旋-轨道相互作用将粒子的自旋与其动量耦合在一起，这是绝缘体中的拓扑边缘状态和分数量子霍尔效应等显著现象的基础。在传统的固态体系中，由于主体材料的复杂和不完善的结构，这些效应很难研究。这个项目将在无缺陷和高度可控的超冷准二维费米气体环境中产生自旋-轨道耦合，以观察新的拓扑相和Majorana费米子，这有望实现无消相干保护的量子态。

Spin-orbit interactions couple a particle's spin to its momentum and underlie remarkable phenomena including topological edge states in insulators and the fractional quantum Hall effect. In conventional solid-state systems these effects are difficult to study due to the complex and imperfect structure of the host material. This project will generate spin-orbit coupling in the defect free and highly controllable environment of an ultracold quasi-two-dimensional Fermi gas to observe new topological phases and Majorana fermions which hold promise for realising decoherence free protected quantum states.
