In chiral twisted double bilayer graphene next to WSe2, zero-degree alignment produces C=+1 Chern insulators at quarter filling while 15-degree alignment produces C=0 insulators, because Ising SOC dominates at zero twist and Rashba SOC at larger twist.

Orientation-tunable correlated Chern insulating states in chiral twisted double bilayer graphene proximitized by WSe2
In chiral twisted double bilayer graphene next to WSe2, zero-degree alignment produces C=+1 Chern insulators at quarter filling while 15-degree alignment produces C=0 insulators, because Ising SOC dominates at zero twist and Rashba SOC at larger twist.
