摘要

量子材料在低强度照明下的光学响应是有趣的，但仍未被探索。在这里，我们建立了一个非线性和非局部模型来描述各种量子材料的介电函数。我们将该模型应用于$1\ mathm {T}-\text{TaS}_{2}$，一种电荷密度波(CDW)材料。我们的模型正确地捕获了CDW堆叠阶段之间的竞争。

Non-linear and non-local optical response in quantum materials

The optical response of quantum materials under low-intensity illumination is interesting and remains unexplored. Here, we develop a non-linear and non-local model to describe the dielectric function of a wide variety of quantum materials. We apply the model to $1\mathrm{T}-\text{TaS}_{2}$, a charge density wave (CDW) material. Our model correctly captures the competition between the CDW stacking phases.
