论文摘要
魔法角度的扭曲双层石墨蛋白是包含莫伊尔图案的远程周期性的系统，以及与各个石墨相关的短范围周期性。这种材料是主要由电子相关性驱动的新型状态的肥沃地。在这里，我们发现无处不在的Casimir力可以用作由魔术角双层石墨元素及其相通过电子相关性确定的量子效应的宏观表现的平台。通过利用对电子和光学响应的综合计算，我们发现Casimir扭矩可以从nematic状态的Drude电导率中探测各向异性，而Casimir力的排斥力可以帮助以魔术角扭曲的双层式双层石墨烯有助于鉴定出拓扑上的非平凡相。
Twisted bilayered graphenes at magic angles are systems housing long ranged periodicity of Moiré pattern together with short ranged periodicity associated with the individual graphenes. Such materials are a fertile ground for novel states largely driven by electronic correlations. Here we find that the ubiquitous Casimir force can serve as a platform for macroscopic manifestations of the quantum effects stemming from the magic angle bilayered graphenes properties and their phases determined by electronic correlations. By utilizing comprehensive calculations for the electronic and optical response, we find that Casimir torque can probe anisotropy from the Drude conductivities in nematic states, while repulsion in the Casimir force can help identify topologically nontrivial phases in magic angle twisted bilayered graphenes.
