Magnetism in two-dimensional (2D) van der Waals (vdW) materials has recently emerged as
one of the most promising areas in condensed matter research, with many exciting emerging …

In the decade since the introduction of van der Waals (vdW) heterostructures for designer
devices, there has been an abundance of studies on the artificial assembly of vdW …

Overlaying two atomic layers with a slight lattice mismatch or at a small rotation angle
creates a moiré superlattice, which has properties that are markedly modified from (and at …

The ability to control the underlying lattice geometry of a system may enable transitions
between emergent quantum ground states. We report in situ gate switching between …

Twisted van der Waals heterostructures have latterly received prominent attention for their
many remarkable experimental properties and the promise that they hold for realizing …

Moiré materials with flat electronic bands provide a highly controllable quantum system for
studies of strong-correlation physics and topology. In particular, angle-aligned …

Flat bands (FBs) can appear in two‐dimensional (2D) geometrically frustrated systems
caused by quantum destructive interference (QDI). However, the scarcity of pure 2D …

Twisted bilayer MoTe 2 is a promising platform to investigate the interplay between band
topology and many-body interactions. We present a theoretical study of its interaction-driven …

Moiré superlattices in twisted van der Waals materials have recently emerged as a
promising platform for engineering electronic and optical properties. A major obstacle to fully …

We show that bilayer graphene in the presence of a 2D superlattice potential provides a
highly tunable setup that can realize a variety of flat band phenomena. We focus on two …
