Correlated insulating states at fractional fillings of moiré superlattices

, 2020
Quantum particles on a lattice with competing long-range interactions are ubiquitous in physics; transition metal oxides1,2, layered molecular crystals3 and trapped-ion arrays4 are a few examples.

Pressure-induced flat bands in one-dimensional moiré superlattices of collapsed chiral carbon nanotubes [PDF]

Two-dimensional (2D) moiré superlattices have been extensively investigated, whereas the one-dimensional (1D) moiré superlattices have remained largely unexplored, due to the difficulty in achieving 1D moiré superlattices experimentally.

Lacunarity of Fractal Superlattices: a Remote Estimation using Wavelets [PDF]

, 2005
The lacunarity provides a useful parameter for describing the distribution of gap sizes in discrete self-similar (fractal) superlattices and is used in addition to the similarity dimension to describe fractals.

Correlation-driven nonequilibrium exciton site transition in a WSe2/WS2 moiré supercell

Nature Communications
Moiré superlattices of transition metal dichalcogenides offer a unique platform to explore correlated exciton physics with optical spectroscopy. Whereas the spatially modulated potentials evoke that the exciton resonances are distinct depending on a site

Electric-Field Switchable Chirality in Rhombohedral Graphene Chern Insulators Stabilized by Tungsten Diselenide

Physical Review X
Chern insulators host topologically protected chiral edge currents with quantized conductance characterized by their Chern number. Switching the chirality of a Chern insulator, namely, the direction of the edge current, is highly challenging due to ...
