Doping fingerprints of spin and lattice fluctuations in moiré superlattice systems
摘要：
扭曲范德华系统提供了前所未有的可能性，以调整不同状态的相关量子物质与外部非侵入性静电掺杂。超导秩序的性质在这方面提出了一个反复出现的悬而未决的问题。在这项工作中，我们定量评估的情况下，自旋波动介导的配对$Γ$谷扭曲过渡金属二硫属化物同质双层。我们自洽和动态计算的掺杂依赖的超导转变温度$T_{\mathrm{c}}$揭示一个超导圆顶与最大的$T_{\mathrm{c}}\approx 0.1-1$ K取决于扭转角。我们比较我们的结果与传统的声子介导的超导性，并确定明确的指纹在掺杂依赖的$T_{\mathrm{c}}$，这使得实验来区分不同的配对机制。
英文摘要：
Twisted Van der Waals systems offer the unprecedented possibility to tune different states of correlated quantum matter with an external non-invasive electrostatic doping. The nature of the superconducting order presents a recurring open question in this context. In this work, we quantitatively assess the case of spin-fluctuation-mediated pairing for $Γ$-valley twisted transition metal dichalcogenide homobilayers. We self-consistently and dynamically calculate the doping dependent superconducting transition temperature $T_{\mathrm{c}}$ revealing a superconducting dome with a maximal $T_{\mathrm{c}}\approx 0.1-1$ K depending on twist angle. We compare our results with conventional phonon-mediated superconductivity and identify clear fingerprints in the doping dependence of $T_{\mathrm{c}}$, which allow experiments to distinguish between different pairing mechanisms.
