We propose a realization of Kondo-lattice physics in moiré superlattices at the interface between a WX2 homobilayer and MoX2 monolayer (where X=S,Se). Under appropriate gating conditions, the interface-WX2-layer forms a triangular lattice of local moments that couple to itinerant electrons in the other WX2-layer via a gate-tunable Kondo exchange interaction. Using a parton mean-field approach we identify a range of twist-angles which support a gate-tuned quantum phase transition between a heavy…

Mott and generalized Wigner crystal states in WSe2/WS2 moiré superlattices
TLDR
Strongly correlated insulating Mott and generalized Wigner phases are detected in WSe2/WS2 moiré superlattices, and their electrical properties and excited spin states are studied using an optical technique.

A new solid-state platform based on moiré superlattices that can be used to simulate problems in strong-correlation physics that are described by triangular-lattice Hubbard models is established.

The authors consider an SU(2) path integral formulation of a Kondo lattice model for heavy fermions that treats the RKKY interaction explicitly. At low temperatures they find the heavy Fermi liquid
Charge-order-enhanced capacitance in semiconductor moiré superlattices
TLDR
Capacitance is established as a powerful probe of the correlated states in semiconductor moiré systems and can be further controlled via sample–gate coupling and demonstrate control of these states via sample-gate coupling.
Topological Insulators in Twisted Transition Metal Dichalcogenide Homobilayers.
TLDR
It is shown that Δ(r) has a topologically nontrivial skyrmion lattice texture in real space, and that the topmost moiré valence bands provide a realization of the Kane-Mele quantum spin-Hall model, i.e., the two-dimensional time-reversal-invariant topological insulator.
