论文摘要
拓扑超导体与Majorana结合状态的外观有关，并具有有希望的拓扑保护量子计算的应用。在这封信中，我们研究了一个系统，其中天空晶体与普通金属连接。通过界面交换耦合，Skyrmion晶体中的自旋波动介导了正常金属中的有效电子电子相互作用。我们研究弱耦合方法中的超导性，并在临界温度和零温度下求解差距方程。由于磁接地态在界面处产生拓扑超导性的非连续性引起的有效电子相互作用的特殊特征。
Topological superconductors are associated with the appearance of Majorana bound states, with promising applications in topologically protected quantum computing. In this Letter, we study a system where a skyrmion crystal is interfaced with a normal metal. Through interfacial exchange coupling, spin fluctuations in the skyrmion crystal mediate an effective electron-electron interaction in the normal metal. We study superconductivity within a weak-coupling approach and solve gap equations both close to the critical temperature and at zero temperature. Special features in the effective electron-electron interaction due to the noncolinearity of the magnetic ground state yield topological superconductivity at the interface.
