标题： Engineering Majorana Kramers Pairs In Synthetic High Spin Chern Insulators

摘要： 高自旋陈数拓扑相为实现双螺旋边缘态提供了一个有前景的低维平台。 在本信中，我们展示了这些边缘态如何能够承载由电子相互作用效应驱动的各种相，包括多通道螺旋Luttinger液体、自旋密度波、超导相以及后两种相的一种新型$\pi$-结类比相，在这些相之间的转变可以被控制。 研究表明，在相互作用系统中的超导相与非相互作用DIII类的时间反演对称拓扑超导体是绝热连接的。 这种连接使Majorana Kramers对作为域壁态稳定在超导相和$\pi$-自旋密度波相之间的界面处，后者表现出时间反演对称的自旋密度波相。 我们讨论了在基于冷原子的平台上利用现有技术实现我们提出的生成Majorana Kramers对的方案的可能性，并探讨了这种方法相对于其他方法可能具有的潜在优势。 显示英文摘要

摘要： High spin-Chern-number topological phases provide a promising low-dimensional platform for realizing double-helical edge states. In this letter, we show how these edge states can host a variety of phases driven by electron interaction effects, including multi-channel helical Luttinger liquid, spin density wave, superconducting phases, and a new type of $\pi$-junction analog of the latter two, where the transitions between the phases can be controlled. The superconducting phase in the interacting system is shown to be adiabatically connected to a time-reversal-symmetric topological superconductor in the non-interacting DIII class. This connection stabilizes Majorana Kramers pairs as domain wall states at the interface between the superconducting and $\pi$-spin-density wave phases, with the latter exhibiting a time-reversal-symmetric spin-density wave phase. We discuss the possibility of realizing our proposed scheme for generating Majorana Kramers pairs in a cold-atom based platform with existing techniques, and how it could offer potential advantages over other approaches.
