Moiré superlattices, the artificial quantum materials, have provided a wide range of
possibilities for the exploration of completely new physics and device architectures. In this …

Polaritons are hybrid excitations of matter and photons. In recent years, polaritons in van der
Waals nanomaterials—known as van der Waals polaritons—have shown great promise to …

Twisted two-dimensional bilayer materials exhibit many exotic electronic phenomena.
Manipulating the 'twist angle'between the two layers enables fine control of the electronic …

Polaritons, originating from the interactions between photons and material excitations, have
attracted attention because of their strong field compression and deeply subdiffractional …

Twisted bilayer graphene is created by slightly rotating the two crystal networks in bilayer
graphene with respect to each other. For small twist angles, the material undergoes a self …

BACKGROUND Light trapped at the nanoscale, deep below the optical wavelength, exhibits
an increase in the associated electric field strength, which results in enhanced light-matter …

Moiré engineering is being intensively investigated as a method to tune the electronic,
magnetic and optical properties of twisted van der Waals materials. Advances in moiré …

Graphene is an atomically thin plasmonic medium that supports highly confined plasmon
polaritons, or nano-light, with very low loss. Electronic properties of graphene can be …

Recent advances in twistronics of low-dimensional materials, such as bilayer graphene and
transition-metal dichalcogenides, have enabled a plethora of unusual phenomena …

Abstract 2D monolayers supporting a wide variety of highly confined plasmons, phonon
polaritons, and exciton polaritons can be vertically stacked in van der Waals …
