Atomic Bose–Einstein condensate in twisted-bilayer optical lattices

Nature, Published online: 22 February 2023; doi:10.1038/s41586-023-05695-4

Quantum simulation of superfluid to Mott insulator transition in twisted-bilayer square lattices based on atomic Bose–Einstein condensates loaded into spin-dependent optical lattices provides a new direction for exploring moiré physics in ultracold atoms.
