Periodically strained graphene harbors correlated electronic phases similar to those previously observed in magic angle twisted bilayer graphene. By precisely rotating two stacked sheets of graphene one can induce superconducting and insulating phases depending on the electric density. This behavior is extremely desirable because it significantly reduces energy losses in electronic devices making them more efficient and durable. Researchers have now proposed an alternative way to obtain similar phases. Their approach relies on periodically straining a graphene sheet rather than stacking layers on top of each other.
