论文摘要
我们建议在[Iemini等人的相互作用的冷原子模型的几个体型限制下，都在实验上可观察到的可观察到的标志。物理。莱特牧师。 118 200404（2017）]。在此限制中，总的现场密度和单体相关性随模型参数而平稳地变化，而计算出的晶格相对末端的相互信息表明，系统向拓扑基态急剧过渡。此外，局部密度和奇偶校验测量为观察超低原子中的基态主要准粒子提供了实验可行的路径。我们的结果为利用少数体系统作为Majoraana物理学的测试场所提供了一个有希望的未来。
We propose experimentally observable signatures of of topological Majorana quasiparticles in the few-body limit of the interacting cold-atom model of [Iemini et al. Phys. Rev. Lett. 118 200404 (2017)]. In this limit, the total on-site density and single-body correlations change smoothly with the model parameters, while the calculated mutual information of opposite ends of the lattice indicates a sharp transition of the system to a topological ground state. Furthermore, local density and parity measurements provide an experimentally viable path for observing the ground state Majorana quasiparticles in ultracold atoms. Our results lay out a promising future for utilizing few-body systems as a testing ground for Majorana physics.
