Flat-band materials such as the kagome metals or moiré superlattices are of intense current
interest. Flat bands can result from the electron motion on numerous (special) lattices and …

Moiré superlattices host a rich variety of correlated electronic phases. However, the moiré
potential is fixed by interlayer coupling, and it is dependent on the nature of carriers and …

Abstract Two-dimensional (2D) superlattices, formed by stacking sublattices of 2D materials,
have emerged as a powerful platform for tailoring and enhancing material properties beyond …

We show that pressure applied to twisted WSe 2 can enhance the many-body gap and
region of stability of a fractional Chern insulator at filling ν= 1/3. Our results are based on …

Motivated by the recent discovery of fractional quantum anomalous Hall states in moiré
systems, we consider the possibility of realizing non-Abelian phases in topological …

The realization of graphene gapped states with large on/off ratios over wide doping ranges
remains challenging. Here, we investigate heterostructures based on Bernal-stacked bilayer …

We study flat bands and their topology in 2D materials with quadratic band crossing points
under periodic strain. In contrast to Dirac points in graphene, where strain acts as a vector …

The recent experimental discovery of the zero-field fractional Chern insulator (FCI) in twisted
MoTe 2 moiré superlattices has sparked immense interest in this exotic topological quantum …

We show that rhombohedral four-layer graphene (4LG) nearly aligned with a hexagonal
boron nitride (hBN) substrate often develops nearly flat isolated low-energy bands with …

Nanofabrication research pursues the miniaturization of patterned feature size. In the current
state of the art, micron scale areas can be patterned with features down to~ 30 nm pitch …
