Twisted-bilayer materials simulated using ultracold atoms

A system of ultracold rubidium atoms confined by two misaligned laser-beam arrays has been used to simulate remarkable structures called twisted-bilayer materials. The atomic technology exhibits phenomena such as superfluidity — the frictionless flow of atoms — typically observed in these materials.

This is a summary of: Meng, Z. et al. Atomic Bose–Einstein condensate in twisted-bilayer optical lattices. Nature https://doi.org/10.1038/s41586-023-05695-4 (2023).
