论文摘要
我们根据多纤维玻尔兹曼方程的静态溶液来计算FESE的列列中的电阻率各向异性。通过在微观多轨模型的水平上引入障碍，我们表明，即使是局部杂质的弹性散射也可能导致电子速度的非平凡各向异性重新归一化，从而挑战了仅基于冷和热点效应的对运输的通常理解。我们的模型同时考虑了$ xz/yz $和最近提议的$ xy $ nematic订购。我们表明，后者具有至关重要的作用，以重现实验测量的各向异性，从而在FESE的大量运输特性上提供了不同列表的直接指纹。
We compute the resistivity anisotropy in the nematic phase of FeSe from the static solution of the multiorbital Boltzmann equation. By introducing disorder at the level of the microscopic multiorbital model we show that even elastic scattering by localized impurities may lead to non-trivial anisotropic renormalization of the electronic velocities, challenging the usual understanding of transport based only on cold- and hot-spots effects. Our model takes into account both the $xz/yz$ and the recently proposed $xy$ nematic ordering. We show that the latter one has a crucial role in order to reproduce the experimentally-measured anisotropy, providing a direct fingerprint of the different nematic scenarios on the bulk transport property of FeSe.
