二维（p（x）+ ip（y））超流体或超导体为研究量子隐形传态、非阿贝尔统计和拓扑量子计算等有趣的物理学提供了一个平台。利用p波Feshbach共振在冷费米子原子光阱中产生这样的超流体是具有挑战性的。在这里，我们提出了一种方法来创建一个p（x）+ ip（y）超流体直接从s波相互作用利用拓扑Berry相，这可以人工生成。我们讨论的方法来检测自发霍尔质量电流，作为手征p波超流体的诊断。
Two-dimensional (p(x) + ip(y)) superfluids or superconductors offer a playground for studying intriguing physics such as quantum teleportation, non-Abelian statistics, and topological quantum computation. Creating such a superfluid in cold fermionic atom optical traps using p-wave Feshbach resonance is turning out to be challenging. Here we propose a method to create a p(x) + ip(y) superfluid directly from an s-wave interaction making use of a topological Berry phase, which can be artificially generated. We discuss ways to detect the spontaneous Hall mass current, which acts as a diagnostic for the chiral p-wave superfluid.
