abstract
The emergence of moir\'e materials, such as twisted transition-metal dichalcogenides (TMDs), has created a fertile ground for discovering novel quantum phases of matter. However, solving many-electron problems in moir\'e systems presents significant challenges due to strong electron correlation and strong moir\'e band mixing. Recent advancements in neural quantum states hold the promise for accurate and unbiased variational solutions. Here, we introduce a powerful neural wavefunction to solve ground states of twisted MoTe2 across various fractional fillings, reaching unprecedented accuracy and system size. From the full structure factor and quantum weight, we conclude that our neural wavefunction accurately captures both the electron crystal at $\nu = 1/3$ and various fractional quantum liquids in a unified manner.

Topological excitonic insulators in electron bilayers modulated by twisted hBN
Hartree-Fock predicts that a twisted-hBN-spaced TMD bilayer at nu=1 can host a p-wave exciton condensate with coexisting quantum anomalous Hall and counterflow superfluid phases.
