In recent years, two-dimensional (2D) van der Waals materials have emerged as a focal
point in materials research, drawing increasing attention due to their potential for isolating …

The layer‐by‐layer stacked van der Waals structures (termed vdW hetero/homostructures)
offer a new paradigm for materials design—their physical properties can be tuned by the …

We study a model of electrons moving in a parent band of uniform Berry curvature. At
sufficiently high parent Berry curvature, we show that strong repulsive interactions …

We show that topological flat minibands can be engineered in a class of narrow gap
semiconductor films using only an external electrostatic superlattice potential. We …

The stacking order and twist angle provide abundant opportunities for engineering band
structures of two-dimensional materials, including the formation of moiré bands, flat bands …

Van der Waals structures present a unique opportunity for tailoring material interfaces and
integrating photonic functionalities. By precisely manipulating the twist angle and stacking …

Superlattice potential modulation can produce flat minibands in Bernal-stacked bilayer
graphene. In this work we study how band topology and interaction-induced symmetry …

Stacking two atomic layers together can induce interlayer (sliding) ferroelectricity that is
absent in their naturally occurring crystal forms. With the flexibility of two-dimensional …

Contemporary quantum materials research is guided by themes of topology and electronic
correlations. A confluence of these two themes is engineered in moiré materials, an …

2D van der Waals (vdW) materials offer infinite possibilities for constructing unique
ferroelectrics through simple layer stacking and rotation. In this work, we stack …
