Electrically controllable valence-conduction band reversals in helical trilayer graphene
Matan Bocarsly, Indranil Roy, Weifeng Zhi +11
In moiré graphene systems, electronic interactions lift spin and valley degeneracies, leading to symmetry-broken ground states. In helical trilayer graphene (HTG), we uncover a di…

hBN alignment orientation controls moiré strength in rhombohedral graphene
Matan Uzan, Weifeng Zhi, Matan Bocarsly +11
Rhombohedral multilayer graphene hosts a rich landscape of correlated symmetry-broken phases, driven by strong interactions from its flat band edges. Aligning to hexagonal boron ni…
