Moire bands in twisted double-layer graphene
read the original abstract
A moire pattern is formed when two copies of a periodic pattern are overlaid with a relative twist. We address the electronic structure of a twisted two-layer graphene system, showing that in its continuum Dirac model the moire pattern periodicity leads to moire Bloch bands. The two layers become more strongly coupled and the Dirac velocity crosses zero several times as the twist angle is reduced. For a discrete set of magic angles the velocity vanishes, the lowest moire band flattens, and the Dirac-point density-of-states and the counterflow conductivity are strongly enhanced.

Emerging network model in a twisted monolayer-rhombohedral graphene
In twisted monolayer–rhombohedral graphene, a realistic parameter regime hosts coexisting nearly flat localized states and quasi-1D propagating modes, forming a hybrid electronic network.

Miniband Generation by Surface Acoustic Waves
Interfering two obliquely propagating surface acoustic waves forms a tunable acoustoelectric superlattice in 2D materials, enabling in-situ control of minibands, flat bands, and nontrivial valley Chern numbers in mass...
