Interacting fermions in topological lattices (C03)

在C3项目中，我们研究了拓扑非平凡光学晶格中镱原子费米子量子气体相互作用的动力学。我们将与项目A6、B2、B3、B8、B9、C1、C4和C9紧密合作。我们想要解决的一个关键问题是相互作用，缺陷和耗散在这种拓扑系统中的作用，以及由这些相互作用引起的集体效应是否可以产生新的物质相，或者相反，禁止非平凡拓扑的出现。我们利用Yb的独特性质来动态实现状态相关晶格中的缺陷，并在综合维度上探索边缘状态动力学。

In project C3 we study dynamics of interacting fermionic quantum gases of Ytterbium (Yb) atoms in topologically non-trivial optical lattices. We will closely collaborate with projects A6, B2, B3, B8, B9, C1, C4 and C9. A key question that we want to address is the role of interactions, defects and dissipation in such topological systems and whether collective effects caused by these interactions can give rise to novel phases of matter or - on the contrary - prohibit the emergence of non-trivial topology. We exploit the unique properties of Yb to dynamically realize defects in state-dependent lattices and explore edge state dynamics in synthetic dimensions.
