Isospin competitions and valley polarized correlated insulators in twisted double bilayer graphene

Le Liu, Shihao Zhang, Yanbang Chu +13

New phase of matter usually emerges when a given symmetry breaks spontaneously, which can involve charge, spin, and valley degree of freedoms. Here, we report an observation of new…
