Abstract

One of the salient features of ultracold atomic systems is that they are intrinsically clean. Nevertheless, artificial impurities can be engineered in atomic systems, which allows one to investigate their effects. In this talk, I will discuss our recent work on the effects of a localized impurity potential on atomic Fermi gases. Such an impurity can be used to manipulate or probe exotic quantum phases of fermionic superfluids. For example, it can be exploited to create the FFLO state in a controlled manner or to realize Majorana edge state in a topological Ferm gas with Rashba spin-orbit coupling.
