MacDonald【麦当劳】2011年发表的的“Moiré bands in twisted double-layer graphene”最为家喻户晓(虽然个人觉得写得不清楚)。在这篇文献中,两人用动量空间中的连续模型(后被称为BM continuum model),对大家关心的低能物理,特别是平带出现的转角(“魔角”,magic angle)做出了准确的预言,并极大减小了计算成本。
Twisted van der Waals heterostructures with small twist angles form moire superlattices with large super-periodic patterns. Mini-Brillouin zones and flat bands are induced, and these can drive the system into strongly correlated regimes. The physical parameters of these superlattices can be varied by ...
