论文摘要
离子的相等间隔的线性链提供了一个测试床,用于研究有限尺寸1D系统中的缺陷形成。特别是,从线性构型到锯齿形的拓扑相过渡相关的缺陷形成很感兴趣。半经验表达为数值结果提供了极好的一致性。 30个离子有限尺寸系统的链和锯齿形拓扑之间的非绝热过渡与非均匀分布的离子链明显区别。因此,可以在目前可访问的离子陷阱实验中测试潜在的均匀千禧kurek模型。此外,我们的研究表明通过相关长度测量出现的集体缺陷行为。
An equally spaced linear chain of ions provides a test-bed for studying the defect formation in a finite size 1D system. In particular, defect formation related to topological phase transition from a linear configuration to a zig-zag one is of interest here. A semi-empirical expression provides an excellent agreement to the numerical results. The non-adiabatic transition between the chain and zig-zag topologies for a finite size system of 30 ions shows clear distinction from non-uniformly distributed ion chain. Thus the underlying Homogeneous Kibble-Zurek model can be tested in presently accessible ion trap experiments. Furthermore, our study indicates collective defect behaviour appearing through the correlation length measurements.
