The moiré pattern observed in stacked noncommensurate crystal lattices, such as heterobilayers of transition metal dichalcogenides, produces a periodic modulation of their band gap. Excitons subjected to this potential landscape exhibit a band structure that gives rise to a quasiparticle dubbed the moiré exciton. In the case of MoS_{2}/WSe_{2} heterobilayers, the moiré trapping potential has honeycomb symmetry and, consequently, the moiré exciton band structure is the same as that of a Dirac… Expand

Interlayer couplings, Moiré patterns, and 2D electronic superlattices in MoS2/WSe2 hetero-bilayers
TLDR
A periodic modulation of the local bandgap in the rotationally aligned MoS2/WSe2 bilayer creates a 2D electronic superlattice and quantitatively determine the influence of interlayer coupling on the electronic structure of the hetero-bilayer at different critical points. Expand
Twist-angle dependence of moiré excitons in WS2/MoSe2 heterobilayers
TLDR
It is shown that not only are moiré excitons robust in bilayers of even large twist angles, but also properties of the moirá reciprocal lattice period are dependant on, and controllable by, theMoiré reciprocal lattices period via twist-angle tuning. Expand
Evidence for moiré excitons in van der Waals heterostructures
TLDR
The observation of multiple interlayer exciton resonances with either positive or negative circularly polarized emission in a molybdenum diselenide/tungsten diselsenide (MoSe2/WSe2) heterobilayer with a small twist angle suggests the feasibility of engineering artificial excitonic crystals using van der Waals heterostructures for nanophotonics and quantum information applications.

Valley-polarized exciton currents in a van der Waals heterostructure
TLDR
The generation and transport over mesoscopic distances of valley-polarized excitons in a device based on a type-II TMDC heterostructure is shown and electrostatic traps are used to increase the exciton concentration by an order of magnitude, opening the route to achieving a coherent quantum state of valley, polarizedexcitons via Bose–Einstein condensation.

Moiré excitons: From programmable quantum emitter arrays to spin-orbit–coupled artificial lattices
TLDR
It is found that the moiré hosts complex hopping honeycomb superlattices, where exciton bands feature a Dirac node and two Weyl nodes, connected by spin-momentum–locked topological edge modes, which underlies the SOC when hopping couples nanodots into superlATTices. Expand
Zitterbewegung of nearly-free and tightly-bound electrons in semiconductors
We show theoretically that non-relativistic nearly-free electrons in solids should experience a trembling motion (Zitterbewegung, ZB) in the absence of external fields, similarly to relativisticExpand

Exciton Propagation and Halo Formation in Two-Dimensional Materials.
TLDR
This work provides microscopic insights into the interplay of exciton propagation and many-particle interactions in TMDs and shows that Auger recombination and emission of hot phonons act as a heating mechanism giving rise to strong spatial gradients in excitonic temperature. Expand
Nature of electron Zitterbewegung in crystalline solids
We demonstrate both classically and quantum mechanically that the Zitterbewegung (ZB, the trembling motion) of electrons in crystalline solids is nothing else, but oscillations of velocity assuringExpand
