摘要：
受扭曲双层石墨烯（TBG）模型中平带研究的启发，我们给出了抽象条件，以保证存在一组离散参数使得周期哈密顿量呈现平带。作为应用，我们证明由TBG手性模型导出的标量算子在一组离散参数下具有平带。
英文摘要：
Motivated by the study of flat bands in models of twisted bilayer graphene (TBG), we give abstract conditions which guarantee the existence of a discrete set of parameters for which periodic Hamiltonians exhibit flat bands. As an application, we show that a scalar operator derived from the chiral model of TBG has flat bands for a discrete set of parameters.
