Observation of First-Order Quantum Phase Transitions and Ferromagnetism in Twisted Double Bilayer Graphene
Twisted graphene multilayers are highly tunable flatband systems for developing new phases of matter. Thus far, while orbital ferromagnetism has been observed in valley-polarized phases, the long-range orders of other correlated phases as well as the quantum phase transitions between different order...
