论文摘要
多年来，激子的强烈相关状态一直是强烈的理论和实验研究的主题。由于新的新兴量子材料，例如范德华（VDW）结合的二色核苷（TMDS），因此该主题蓬勃发展。我们分析了最近在双层TMD TMD异质结构中观察到的带电层间激子的集体特性。我们预测新的紧密相关的相 - 晶体和Wigner晶体 - 可以通过改变其室内层间隔距离，可以通过正确选择的电子孔有效质量的TMD双层选择性实现。我们的结果为具有量子VDW异质的非线性相干控制，电荷运输和旋转应用应用开辟了新的途径。
Throughout the years, strongly correlated coherent states of excitons have been the subject of intense theoretical and experimental studies. This topic has recently boomed due to new emerging quantum materials such as van der Waals (vdW) bound atomically thin layers of transition metal dichalcogenides (TMDs). We analyze the collective properties of charged interlayer excitons observed recently in bilayer TMD heterostructures. We predict new strongly correlated phases - crystal and Wigner crystal - that can be selectively realized with TMD bilayers of properly chosen electron-hole effective masses by just varying their interlayer separation distance. Our results open up new avenues for nonlinear coherent control, charge transport and spinoptronics applications with quantum vdW heterostuctures.
