Multilayer graphene with a superlattice potential

Bernal stacked bilayer graphene subject to a superlattice potential can realize topological and flat bands [Ghorashi et al., Phys. Rev. Lett. 130, 196201 (2023)]. In the present work, we extend study of on heterostructures trilayer quadrilayer graphene. Comparing Bernal- chirally multilayers reveals that latter are more suitable for realizing stacks many bands. On other hand, Bernal-stacked Imposing two simultaneous potentials enhances viability both regimes.
