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

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 …

We propose magic-angle helical trilayer graphene (HTG), a helical structure featuring
identical rotation angles between three consecutive layers of graphene, as a unique and …

Structured light refers to the ability to tailor optical patterns in all its degrees of freedom, from
conventional 2D transverse patterns to exotic forms of 3D, 4D, and even higher-dimensional …

Moiré graphene systems have attracted considerable attention in the past 3 years because
they exhibit exotic phenomena including correlated insulating states, unconventional …

Euclidean geometry is the fundamental mathematical framework of classical crystallography.
Traditionally, layered materials are grown on flat substrates; growing Euclidean crystals on …

Twisted stacking of van der Waals materials with moiré superlattices offers a new way to
tailor their physical properties via engineering of the crystal symmetry. Unlike well-studied …

We review recent work on low-frequency Floquet engineering and its application to quantum
materials driven by light, focusing on van der Waals systems hosting Moiré superlattices …

The broadband graphene absorber designs for a visible and near-infrared (NIR) regime is
developed in the study. The gold resonator is placed over an MgF 2 substrate which is …

The work intends to extend the moiré physics to three dimensions. Three-dimensional moiré
patterns can be realized in ultracold atomic gases by coupling two spin states in spin …
