我们数值研究扭曲MoTe₂中任意子与电子trion结合形成任意子分子，发现其光致发光红移依赖任意子分数电荷和动能，与实验定性一致。
AI中文摘要：
受近期在扭曲MoTe₂同双层中的光学测量启发，我们数值研究了游走任意子与普通电子束缚态的结合。利用一个最小少体模型，其中任意子与空穴和电子处于高斯捕获势中，我们表明由任意子和普通电子trion组成的分数电荷束缚态在局部静电缺陷附近可能变得有利。由此产生的物体是一个任意子分子，其中任意子束缚于trion“核”上，而该核则定位于缺陷处并可被光学激发。我们发现，所得的任意子-trion相对于普通束缚trion可表现出光致发光红移，对于与扭曲MoTe₂相关的参数，其结合能处于meV量级。我们发现该红移的值同时依赖于任意子的分数电荷及其动能，从而编码了任意子的普适和非普适性质。我们的结果与扭曲MoTe₂中的观测定性一致。
英文摘要：
Motivated by recent optical measurements in twisted MoTe$_2$ homobilayers, we numerically study the binding of itinerant anyons to ordinary electronic bound states. Using a minimal few-body model of an anyon alongside holes and electrons in a Gaussian trapping potential, we show that a fractionally charged bound state comprised of an anyon and an ordinary electronic trion can become favorable nearby local electrostatic defects. The resulting object is an anyonic molecule wherein the anyon is bound to the trion ``nucleus,'' which in turn is localized to the defect and can be excited optically. We find that the resulting anyon-trion can exhibit a photoluminescence red-shift relative to the ordinary trapped trion, with binding on the meV scale for parameters relevant to twisted MoTe$_2$. We find that the value of this red-shift depends on $\textit{both}$ the anyon's fractional charge and its kinetic energy, thereby encoding both universal and non-universal anyon properties. Our results are qualitatively consistent with observations in twisted MoTe$_2$.
