An AI-driven robotic system for two-dimensional hetero-assemblies
Xiaoxi Li, Jinkun He, Haojie Liu +27
Nanomaterials stacked on-demand, such as rotationally assembled two-dimensional (2D) van der Waals (vdW) layered compounds, provides a versatile platform for quantum simulation and…
Chiral-helical junctions in screened graphene
Bilal Kousar, Selma Franca, David Perconte +14
Reproducibility and quantization in quantum spin Hall platforms is a persisting challenge, limiting their use in hybrid realizations of topological superconductivity. We report rob…
Topologically nontrivial and trivial flat bands via weak and strong interlayer coupling in twisted bilayer honeycomb optical lattices for ultracold atoms
Wenjie Sui, Wei Han, Zheng Vitto Han +2
In recent years, flat electronic bands in twisted bilayer graphene (TBG) have attracted significant attention due to their intriguing topological properties, extremely slow electro…
Electrical switching of Chern insulators in moire rhombohedral heptalayer graphene
Zhiyu Wang, Qianling Liu, Xiangyan Han +14
In orbital Chern insulators, the chemical potential acts as a tuning knob to reverse chirality in dissipationless edge currents, enabling electric-field control of magnetic order-k…
A two-dimensional semiconductor-semimetal drag hybrid
Yingjia Liu, Kaining Yang, Kenji Watanabe +4
Lateral charge transport of a two-dimensional (2D) electronic system can be much influenced by feeding a current into another closely spaced 2D conductor, known as the Coulomb drag…
Quantized Landau-level crossing checkerboard in large-angle twisted graphene
Baojuan Dong, Kai Zhao, Kenji Watanabe +6
When charge transport occurs under conditions like topological protection or ballistic motion, the conductance of low-dimensional systems often exhibits quantized values in units o…
